NON-ALCOHOLIC BEVERAGES

In this lesson we shall discuss about the beverages. After completion of this lesson you will be able to understand:

Beverages and their classification

Non-alcoholic beverages

Preparation of non-alcoholic beverages.

‘Beverage’ is the term which refers to all kinds of potable drinks which have thirst-quenching, refreshing, stimulating and nourishing qualities. By refreshing, one means the replenishment of fluid loss from the body due to perspiration. Simulation results in increase of the heart beat and blood pressure. This is due to the intake of spirits (alcohol) or tea (tannin) and coffee (caffeine). Nourishment is provided by the nutrients in the beverages, especially fruit juices.

Most of the beverages supply energy in the form of sugar or alcohol. They also provide other nutrients like mineral salts and vitamins. For example, milk gives calcium and citrus fruits give vitamin C.

Generally, people drink for one or more of six reasons; to quench thirst, to get drunk, to enjoy a social setting (social drinking), to enjoy the taste of the beverage, to feed an addiction (alcoholism), or as part of a religious or traditional ceremony or custom (proposing toast).

A beverage is a liquid formulation specifically prepared for human consumption. The word "Beverage" has been derived from the Latin word "bever" meaning rest from work. After work, one tends to feel thirsty due to fluid loss through perspiration and one is inclined to drink water or other potable beverages to compensate fluid loss.

Beverages can be broadly classified into:

·         Alcoholic Beverages.

·         Non-alcoholic Beverages.

The term non-alcoholic beverages cover drinks that are either totally free from alcohol or that have less than 0.5 percent alcohol by volume. Such drinks are generally drunk for refreshment, or to quench people's thirst.

Non-alcoholic beverages can be classified as: -

STIMULATING TEA, COFFEE, COCOA

Stimulating:

Tea: is one of the most widely-consumed stimulant

t beverage in the world. It has a cooling, slightly bitter, astringent flavor. It has almost no carbohydrates, fat, or protein.

Coffee: is a widely consumed stimulant beverage prepared from roasted seeds, commonly called coffee beans, of the coffee plant. Once brewed, coffee may be presented in a variety of ways. Drip brewed, percolated, or French-pressed / cafetière coffee may be served with no additives (colloquially known as black) or with sugar, milk or cream, or both. When served cold, it is called cold coffee/ iced coffee.

Cocoa: it is a powder made from cacao seeds (bean) after they have been fermented, roasted, shelled, ground, and freed of most of their fat. A beverage is made by mixing this powder with sugar in hot water or milk. It is a rich source of theobromine which acts as a stimulant.

TEA

Tea is the most preferred beverage in the world; tea is a stimulating and refreshing drink. Tea was discovered by accident over 5000 years ago when leaves from a tea bush accidentally dropped into some boiling water and delicately flavored the liquid.

All tea comes from the "Camellia sinensis", an evergreen shrub that may grow up to 60 feet in the wild. When cultivated for harvest, the tea bushes are kept to a height of about three feet. There are over 3000 varieties of tea each with their own specific characteristics. Tea leaves have a characteristic oval shape and serrated edge. Younger the leaves better the quality of the tea.

The kind of tea obtained is determined by the manufacturing process and treatment. The principle flavor components of tea are caffeine, tannin yielding compounds and small amounts of essential oils. Caffeine provides the stimulating effect, tannin the colour, body and taste to the extract and the essential oils contribute the characteristic aroma. It is predominantly grown in India, Ceylon, China and Japan. Chinese tea contains less tannin than the other varieties.

Tea is mostly named after the region in which they are cultivated. Example: Assam tea is named after the Assam region in India, and Keemun is named after the Keemun region of china. The British introduced the habit of drinking tea in India.

Stages in the Manufacture of Tea :- 

In the process of making tea, the  leaves from tea plant are transformed into the dried  leaves for brewing tea, the types of tea are differentiated  by the processing they undergo :-

1)      Plucking: - Leaves are handpicked while they are still young. “Flush” refers to newly-grown vegetative shoots composed of the terminal bud and two other young leaves immediately below it are picked from the tea plant twice a year during early spring and early summer.

2)      Withering: - the tea leaves begin to wither soon after picking. The withering process is used to remove excess moisture from the leaves. The leaves are put under sun light.

3)      Fermentation/oxidation: - withered leaves are subjected to oxidation. During oxidation the leaves are left on their own in a climate controlled room where they progressively turn dark.

4)      Firing: - this process is accomplished to stop the fermentation at desired oxidation level.

5)      Rolling: - the tea leaves are then rolled into spirals and different shapes.

6)      Drying: - This process is carried out to prepare the leaves for sale. Mechanical dryers are used.

7)      Ageing/Curing: - while not always required, but some teas require additional ageing, secondary fermentation to develop their complex flavors.

8)      Sorting:- Done by different grades:

       I.            Broken

    II.            Fanning – Small fragments of broken leaves.

 III.            Dust – This is left when fanning is shifted. This is popular as catering tea and is used in tea bags because it infuses quickly and is quite strong.

Tea dealers use letters to denote various grades of tea. These are stamped on the tea chests.

P – Pekoe: Indicates larger pieces: small, tightly rolled leaves together with open leaves.

O - Orange: Indicates Good quality tea.

F - Flowery grade: Indicates a flowery grade of good flavor.

Orange Pekoe: Long, thin leaves that are closely twisted, yellow leaf tips and bud leaves are sometimes included.

Souchang: Largest and coarsest of the whole leaf grade.

Blending: Blend of various qualities, sizes and grades of tea to give a uniform product.

Special kinds of Tea

Ø  Earl Gray: Blend of Indian and China teas and Bergamot oils. It is light and delicately scented. Bergamot is a pear shaped orange and the oil is extracted from the rind.

Ø  Assam: Strong, recuperative tea.

Ø  Darjeeling: Flavor of Muscatel, can be drunk with lemon or milk.

Ø  Jasmine: China tea mixed with scented jasmine flavors, best drunk with slice of lemon.

Ø  Lady Londonderry’s mixture: a special blend of China, Indian and Formosa teas.

Ø  Green gunpowder: China tea with curled leaves, which looks like gunpowder.

Ø  Lapsang Souchong: A distinctive China tea with tarry taste; quite pungent.

Ø  Tisanes: Teas that have herbal base, e.g.- jasmine and chamomile.  

Basic forms of Tea

The climate, soil conditions where the tea is grown, and how the tea is processed, determines the flavor characteristics of the tea. Tea is harvested after each flush - the sprouting of the top two leaves and bud. Tea pickers’ motto is ‘two leaf and a bud.’ The top two leaves and bud are hand plucked and then processed into any of the four types of tea, which are Black, Green, oolong, and White.

Black Tea

 The leaves are withered, then rolled till they become soft and massy. This is done to break up the fiber and cells of the leaf to liberate the constituents so that their extraction is easy. The leaves are then fermented. During the process of fermentation some of the acid in the leaves oxidizes and is converted into less soluble forms while more essential oils develop. After fermentation is complete, the leaves are fired in a drying machine. Some of the popular black teas include English Breakfast, and Darjeeling.

Green Tea Skips the oxidizing step. It is simply withered and then dried. It has a more delicate taste and is pale green/ golden in color. The main difference between black tea and green tea is, the former is fermented while the latter is not. Since the purpose of fermentation is to make tannin less soluble, an infusion of green tea has more tannin in it, astringent and slightly bitter to taste.

Oolong tea is popular in China, it is withered, partially oxidized, and dried. Oolong is a cross between black and green tea in color and taste.

White tea is the least processed. A very rare tea from China, White tea is not oxidized or rolled, but simply withered and dried by steaming. The best tea generally produces a pale-coloured infusion and the depth of colour is not necessarily a 'sign of strength.’ Freshly infused tea is harmless to normal digestion; continued infusion extracts the tannin, a bitter substance which is harmful.

 Storage of Dried Tea

1.      Tea easily absorbs moisture and odors and so it is essential that it is kept in a cool dry place away from any strong smelling items.

2.      Tea must be stored in an airtight container not exposed to light and used within a reasonable time. Because light breaks down the quality (photo-oxidation) of tea, glass containers are not suitable for the storage of tea unless stored away from light.

3.      If the tea in chest, they should be kept off the ground and at 16 cm. or 6 inches away from the wafts. This allows a current of air to circulate round the tea chest and averts dampness.

4.      Once a chest is opened it is advisable to put a close-fitting lid over it.

Preparation of Tea

Tea brewing or preparation is an art that is simple to perform but which also requires some care, to do well. While essentially tea is brewed by adding boiling water to the dry leaf, the quantity of leaves, the temperature of the water and timing is of vital concern. The following is a guide for the preparation of tea. The basic rule of thumb to start is 'one teaspoon of loose-leaf tea per cup.

1.      Warm your empty tea pot by filling it with hot water. This will prevent the hot water from cooling too quickly when leaves are added. Use a good quality and properly stored tea leaves/dust/tea bags.

2.      Boil freshly drawn tap water. If the quality of your tap water is poor, try using filtered or bottled spring water. For black tea, use the water when it comes to a boil. Water left boiling too long will de-aerate. This will result in a flat tasting tea. For green tea, the water should be heated to a lower temperature (usually approximately 80-90 degrees Celsius), which may vary from tea to tea.

3.       Empty the hot water from your tea pot and add 2.25g or one rounded teaspoon of tea leaves for each cup of water (or one heaping teaspoon per mug), placing the tea directly into the bottom of the pot or using a basket infuser. Tea ball strainers, while convenient, often yield poorer tasting tea as they are often too small to allow all of the leaves to fully unravel its contents. If you do use a tea ball, be sure to use one that is sufficiently large to pack the tea loosely.

4.      Add the freshly boiled water over the leaves in the tea pot.

5.      Brew tea for the appropriate length of time. Time needed to brew tea varies depending on the leaves being used and the drinker's individual taste. Careful timing is essential for brewing tea. A very general rule to follow is the smaller the leaf, the less time required for brewing. Broken grades of tea leaves and most Darjeeling teas usually only need 3-4 minutes to brew. Whole-leaf teas often need 3-5 minutes. All teas, however, will become bitter due to higher tannin extraction if brewed for longer than 5 or 6 minutes. When brewing tea, time with a timer, and not with your eyes. It is a common mistake to brew the tea until it looks a particular color or shade. The color of tea is a poor indicator of the tea's taste.

6.      If you use a basket infuser or a tea ball, remove these promptly when the brewing time has expired. If you placed the tea directly into the pot, pour the tea into the cups through a strainer to catch the leaves. In this instance, if you do not wish to serve your tea immediately, pour your tea through a strainer into another pre-heated tea pot.

7.      Tea sometimes is brewed with spices like fresh ginger, dried ginger powder or cardamoms to enrich the flavor. Milk and sugar should be added according to individual taste. Adding of milk first or last does not make any significant difference in the taste of tea - but many people have their choice some like to add milk first and some afterwards. Sugar must be added last. Tea is also taken hot with sugar and slices of lemon. This is known as Russian Tea. For preparing iced tea: prepare strong tea. Pour over crushed ice on which placed a sprig of mint and topped with lemon slices. Instant tea: Of late completely water soluble tea powder is getting popular. Another convenient method of preparing tea is to use tea bags.

COFFEE

There is evidence to suggest that coffee trees were cultivated about 1000 years ago in the Yemen. Coffee berries, which contain the coffee bean, are produced by several species of small evergreen bush of the genus Coffea. The two most commonly grown species are Coffea canephora (also known as Coffea robusta) and Coffea arabica. These are cultivated in India, Latin America, Southeast Asia, and Africa. Once ripe, coffee berries are picked, processed to remove the mesocarp, and dried. The seeds are then roasted, undergoing several physical and chemical changes. They are roasted to various degrees, depending on the desired flavor. They are then ground and brewed to produce liquid coffee which is also known as coffee decoction. Coffee can be prepared and presented by a variety of methods to cater the need of local palate.

There are two types of coffee:

1)  Pure coffee – prepared from coffee beans only.

2)  French coffee – contains chicory.

Coffee is always brewed by the user immediately before drinking. In most areas, coffee may be purchased unprocessed, or already roasted, or already roasted and ground. Coffee is often vacuum packed to prevent oxidation and lengthen its shelf life.

Processing of Coffee Beans

Coffee preparation is the process of turning coffee beans into a beverage. While the specific steps needed vary with the type of coffee desired and with the raw material being utilized, the process is composed of four basic steps; raw coffee beans must be roasted, the roasted coffee beans must then be ground, the ground coffee must then be mixed with hot water for a certain time (brewed), and finally the liquid coffee must be filtered off from the spent powder.

ü    Beans are washed:

ü    Dried:

ü    Skinned:

ü    Shipped:

ü    Roasted:  Roasting coffee transforms the chemical and physical properties of green coffee beans into roasted coffee products. The roasting process is integral to producing a savory cup of coffee. When roasted, the green coffee bean expands to nearly double its original size, changing in color and density. As the bean absorbs heat, the colour shifts to yellow and then to a light "cinnamon" brown then to a dark and oily colour. During roasting, oils appear on the surface of the bean. The roast will continue to darken until it is removed from the heat source. Coffee can be roasted with ordinary kitchen equipment (frying pan, grill, and oven) or by specialized appliances. Sometimes, butter fat (melted butter / ghee) is added during roasting to enhance the flavor of the resultant powder.

·         Light roasting – for mild beans to develop the aroma.

·         Medium roasting – for stronger flavor.

·         Full roasting - for a bitter flavor.

·         High roasting - accentuates the strong, bitter aspects of coffee, much of the original flavor is lost.

ü    Grinding: The whole roasted coffee beans are ground, which is also known as milling, to facilitate the brewing process. It preserves the flavor as much as possible. Three grades are available:

v    Fine ground coffee, which gives a decoction with a high body.

v    Medium

v    Coarse ground powder is more suitable for preparing coffee decoction by percolation. It retains the aroma and flavor better.

The fineness of grind strongly affects brewing, and must be matched to the brewing method for best results. Brewing methods which expose coffee grounds to heated water for longer require a coarser grind than faster brewing methods. Uniformly ground coffee is better than the mixture of sizes produced by a mill with chopping blades. Many coffee drinkers grind the beans themselves immediately before brewing. There are four methods of grinding coffee for brewing: burr-grinding, chopping, pounding, and roller grinding.

ü    Blending: Blended with chicory roots of coffee, dried and powdered.

 Methods of Preparation of Coffee

General methods of preparation of coffee are given below. This is followed by specific methods of brewing coffee which is given under appropriate headings.

Brewing Coffee can be brewed in several different ways, but these methods fall into two main groups depending upon how the water is introduced to the coffee grounds.

·         If the method allows the water to pass only once through the grounds, the resulting brew will contain mainly the more soluble components (including caffeine).

·         If the water is repeatedly cycled through the beans (as with the common percolator), the brew will also contain more of the relatively less soluble, and bitter-tasting, compounds found in the bean, but for this coarse ground coffee will be required.

Boiling Despite the name, care should be taken not to actually boil coffee for more than an instant because the decoction becomes bitter.

                               (COFFEE TO BOIL IS COFFEE TO SPOIL)

·         The simplest method is to put the ground coffee in a cup, pour in hot water and let it cool while the grounds sink to the bottom. This is a traditional method for making a cup of coffee   (known as "mud coffee")

·         "Cowboy coffee" is made by simply heating coarse grounds with water in a pot, letting the grounds settle and pouring off the liquid to drink, sometimes filtering it to remove fine grounds. The above methods are sometimes used with hot milk instead of water. Water temperature is crucial to the proper extraction of flavor from the ground coffee. The recommended brewing temperature of coffee is 93°C (199.4°F). If cooler, some of the soluble that make up the flavor will not be extracted. If the water is too hot, some undesirable, bitter, components will be extracted, adversely affecting the taste. If coffee is heated to boiling point only very briefly, the taste will be little affected; the longer it is kept at a high temperature the worse the taste becomes.

                              

Steeping A cafeteria (or French press) is a tall, narrow cylinder with a plunger that includes a metal or nylon mesh filter. Coffee is placed in the cylinder and boiling water is poured on. The coffee and hot water are left in the cylinder for a few minutes (typically 4'-7') and the plunger is pushed down leaving the filter immediately above the grounds, allowing the coffee to be poured out while the filter retains the grounds. Depending on the type of filter, it is important to pay attention to the grind of the coffee beans, though a rather coarse grind is almost always called for. A plain glass cylinder may be used, or a vacuum flask arrangement to keep the coffee hot.

Drip Brew Drip brew (also known as filter or American coffee) is made by letting hot water drip onto coffee grounds held in a coffee filter (paper or perforated metal). Strength varies according to the ratio of water to coffee and the fineness of the grind, but is typically weaker than espresso, though the final product contains more caffeine. By convention, regular coffee brewed by this method is served in a brown or black pot (or a pot with a brown or black handle), while decaffeinated coffee is served in an orange pot (or a pot with an orange handle).    

                                                    

 Moka Pot Method There is an art to making coffee in a moka pot that includes the amount of water, the amount and grind of the coffee, the compactness of the coffee grounds in the filter and the heat of the water used to brew it. It is possible to make excellent coffee without any acidity or bitterness in a moka pot if you follow simple procedures listed below:

1)      Place your kettle of cold water on your stove burner and heat water until hot. Depending on the quality of your water, you may find that using filtered water significantly improves the taste of your coffee.

2)      Grind your coffee. Grind just a little coarser than for an espresso machine (fine, espresso grind of dark roasted coffee). Just coarse enough so it doesn't go through the upper filter holes or block them.

3)      Place hot water in the bottom section of the pot up to the level of the safety valve.

4)      Insert the filter basket. Fill the filter basket with ground coffee until it is level and then level off with a knife. Do not compact the coffee, because as the water reaches the grounds they will expand effectively tamping your coffee for you.

5)      Make sure the filter disk and gasket are in place in the top portion of the pot. Screw the top    section onto the bottom section of the pot and tighten to obtain a perfect seal. If using a stovetop moka pot, place it on the stove on medium to medium-high heat. When hot, the air and water trapped inside the bottom tank expand due to the heat being applied the device. As this happens, it pushes the hot water up a tube, through the coffee grinds, and out of the spout into the top chamber of the pot.

6)      When the water in the tank has been exhausted, that's when you hear the ‘gurgle,’ that signifies the drink is ready to pour (approximately 4-5 minutes). Brewing is completed when all the water has been percolated into the top chamber. Remove the moka pot from the stove.

Do not put the pot in the dishwasher. Wash the pot in mild detergent and water and dry   thoroughly after each use. Always keep your moka pot scrupulously clean. Disassemble the moka pot after every use and clean the filter and top pot, being sure that you clean the underside of the top pot. Every few weeks, run some vinegar through the moka pot as if you were brewing coffee to get rid of any mineral deposits left behind by hard water.

 Pot Method

·         Warm an earthenware pot or jug. Put in 3 level teaspoons of fresh coffee powder (coarse    grind) for each 250 ml cup.

·         Pour water which has started to boil over the powder and stir. Cover the pot and let it stand near the fire for 5 to 7 minutes.

·         Pour the coffee through a fine meshed sieve or cloth. Add milk and sugar to taste.

 Filter Method

Several types of filters are available. Stainless steel or brass filters are the best, but the latter should be properly tinned, or else the coffee will be spoilt. Glass or china containers are good but are fragile. Copper should not be used because of possible copper poisoning.

·         Put in 3 level teaspoons of coffee powder (fine or medium grind) to each 250 ml. or 8 oz. cup. Press the plunger down lightly over the powder.

·         Pour water which has just come to boil over (he plunger in a circular motion. Let it stand for 5 to 7 minutes.

·         Coffee can be poured out straight from the lower vessel and milk and sugar added as required.

 Percolator Method

·         Place the ground coffee powder in the centre section of a clean warm percolator on a fine strainer fitted inside and resting on a paper filter (a pinch of salt is mixed with the coffee).

·         Pour fresh boiling water slowly through the top section.

·         The water passes through the coffee, is strained and collects in the bottom section of the apparatus.

Espresso or Caffè Espresso

Espresso is a concentrated coffee beverage brewed by forcing very hot, but not boiling water under high pressure through coffee that has been ground to a consistency between extremely fine and powder.

The defining characteristics of espresso include a thicker consistency than drip coffee, a higher amount of dissolved solids than drip coffee per relative volume, and a serving size that is usually measured in shots, which are between 25 and 30 ml (30ml=1 fluid ounce) in size. Espresso is chemically complex and volatile, with many of its chemical components quickly degrading due to oxidation or loss of temperature. Properly brewed espresso has three major parts: the heart, body, and the most distinguishing factor, the presence of crema, reddish-brown foam that floats on the surface of the espresso. It is composed of vegetable oils, proteins and sugars. Crema has elements of both emulsion and foam colloid.

 Instant Coffee

A thick coffee decoction is prepared first and then it is either spray dried to a fine powder or freeze dried to granules. When added to hot water it dissolves completely leaving no residue.

Turkish Coffee

It is heavily laced with cardamom and is quite thick in consistency. It is a traditional after meal drink in many Arab countries.

COCOA

Cocoa, besides being a stimulant, is also a food. It is prepared from the seeds (beans) of a tree called theobromo cacao, grown in South and Central America, the West and East Indies and along the Gold Coast and adjacent areas in Africa. Common Commercial verities are criolo (fine quality) and trinitario (medium quality). The pods are gathered in heaps and cut open with sharp rounded knives. The cocoa beans which are covered with a moist, glistening sweet white pulp (mucilage) are scooped out. Oxidation

begins almost at once causing the beans to become brown. Therefore, as soon as possible, they must be placed on fermenting heaps and are spread in the sun to remove the moisture so that spoilage does not set in. However, fermentation is necessary to get the finest possible flavor. This is accompanied by a rise in temperature and the transformation of natural sugars to acetic and other acids. After several days, this operation is complete and the beans are allowed to dry. They are then ready to be packed and shipped.

ORIGIN: - The first chocolate beverage is believed to have been created by the Mayan people  around 2000  years ago.  The beverage became popular in Europe after being introduced from Mexico after its introduction to Europe, the drink slowly gained popularity. Until the 19^th century, hot chocolate was even used medicinally to treat ailments such as stomach diseases. Today, hot chocolate is consumed throughout the world and comes in multiple variations including the very thick cocoa served in Italy and the thinner hot cocoa that is typically consumed in United States.

Nearly 70 % of the world crop is grown in West Africa.

MANUFACTURING OF COCOA:-

Producing cocoa is one of the complicated processes. It requires expert monitoring, technology and a lot of patience. To simplify it the cocoa is a byproduct of making block chocolate process.

·         Chocolate is made from the dried and partially fermented seeds of cocoa tree.

·         When the pods ripen, they are harvested from the cocoa tree.

·         The pods itself is green when ready to harvest, rather than red or orange.

·         Normally red or orange pods are considered to be of inferior quality, because their flavors and aromas are poor.

·         The harvested pods are opened, the pulp and cocoa seeds are removed and the rind is discarded.

·         The pulp and seeds are then piled in heaps, placed in bins or laid out on crates, for several days.

·         During this time, the seed and pulp undergo “sweating”, where the thick pulp liquefies as it ferments. The fermented pulp trickles away, living cocoa seeds behind to be collected.

·         The seeds are then dried, cleaned, roasted (roasting develops the flavor and colour), cracked (passed through corrugated rollers to break their shell and separate the germ) to remove the nibs (roasted, de-hulled and de-germed beans are called nibs) and then ground to a smooth   liquid containing 55% fat.

·         The fat is then pressed out to leave about 25 % of the original and the resultant mass   is ground into fine powder, mixed with flavouring materials and homogenized,is the cocoa from which beverage is prepared.

Cocoa contains the bromine, caffeine as well as starch, fat, nitrogenous compounds and salts. So, apart from being a stimulating drink, it is also a food. Cocoa can be prepared in milk only, or in milk and water, mixed to suit the taste of the individual. The powder is mixed with sugar to avoid lumping. A little cold milk is added and a thick even paste made. Either hot milk or hot milk and water are pored over. The preparation is then allowed to boil for a few minutes which improve the flavor. A pinch of salt added at the beginning enhances the flavor.

Service: Tea cup, saucer, tea spoon (served from right hand side)

Refreshing:

Waters:

Waters can be classified as-

·         Still

·         Naturally sparkling

·         Carbonated during bottling

Bottled Water: It is of two types- Mineral and spring water.

Mineral water is the water containing minerals or other dissolved substances, which are strictly controlled. This alters its taste or gives it therapeutic value. Salts, sulfur compounds, and gases are among the substances that can be dissolved in the water. Mineral water can often be effervescent. Mineral water can be prepared or can occur naturally.

According to their chemical properties, they are classified as:

·         Alkaline waters- Help treatment of gout and rheumatism.

·         Aperient waters- Have saline constituents like sulphate of magnesia or sulphates of soda.

·         Lithiated waters- These are rich in Lithia salts.

·         Table waters: These are less mineralized than other natural spring waters and are mainly alkaline. They may be taken at meal times, either as water or may be mixed with light wine or spirits.

Spring water is often bottled and sold as mineral water with some regulations concerning hygiene.

Natural spring water:  spring water is the water derived from underground formation from which water flows naturally (artesian) to the surface of the earth. Minerals become dissolved in the water as it moves through the underground rocks. This may give the water flavor and even carbon dioxide bubbles, depending upon the nature of the geology through which it passes. The uniqueness of these mineral waters is that they have medicinal value.

Service: Most guests prefer mineral water in place of tap water. Mineral waters are served chilled at temperatures range of 7-10 degree C. but without addition of ice unless requested by the guest. It can be served in Paris goblet, Highball, or slim jim glass. Mineral water may also be mixed with alcoholic drink and consumed.

Soft Drinks:   these beverages are charged or aerated with carbonic gas. The charging with carbonic gas imparts the pleasant effervescent characteristic of these beverages. Carbonation occurs when carbon dioxide is dissolved in water or an aqueous solution. This process yields the "fizz" to carbonated water and sparkling mineral water. Drinks are acidified, sweetened, coloured, carbonated, and often chemically preserved. The water used should be well purified and is free of micro organism, dissolved metals, and organic compounds. These aerated drinks are available in different flavors and colours. Example: soda water, dry ginger, fizzy lemonade, ginger beer, coca-cola, pepsi, and others.Synthetic flavours are generally used because

·         Natural flavours added to the drinks do not give standard products.

·         Natural flavor extracts undergo changes in the presence of light, acid and storage.

·         Natural flavours do not transport pigments of sufficient depth.

·         Natural flavours are unstable in acidic conditions. Acids used are Citric, Malic, Tartaric, and phosphoric. Dissolved carbon dioxide also produces acidity.

Sodium Benzoate is a common preservative used in soft drinks.

Tonic- It is a aerated drink, sweetened and flavoured with natural fruit and plant extracts including quinine. It is drunk straight with ice and a slice of lemon or added in cocktail. It is generally used with gin.

Gingerale- Consists of aerated water with coloring and ginger essence.

Lemonade- Consists of lemon juice, sugar and aerated water.

Service: They can be taken chilled anytime of the day- Neat or mixed with alcoholic drinks or syrups. They are served in highball glasses or Tom Collins. Straw holder is placed on the table.

Nourishing:

Juice: Juice is prepared by mechanically squeezing or macerating fresh fruits or vegetables without the application of heat or solvents. Popular juices include, but are not limited to, apple, orange, prune, lemon, grapefruit, cherry, pineapple, tomato, carrot, grape, strawberry, cranberry, pomegranate guava, and celery. It has become increasingly popular to combine a variety of fruits into single juice drinks. Popular blends include cran-apple (cranberry and apple) and apple and blackcurrant. Juices are also used for cocktails and mixing with spirits. Fruit juices can be either fresh or preserved (canned or bottled or tetra packs). Tomato juice and carrot juice are from vegetable family that fall under the category of nourishing drinks.

Juices are served with or without ice in Paris goblet/Highball/ Tom Collins. The pre poured glass is brought from dispense bar/still room to the table and placed on a coaster from the right-hand side of the guest. Straw holder may be placed on the table.

·         Fresh fruit juices are served in a highball glass on a doily covered under liner, with tea spoon; Sugar syrup is served separately.

·         Preserved fruit juices are served in 8oz glass on a doily covered under liner. Since they already have high sugar content, there is no need to give sugar syrup separately.

Syrup : Syrup is a thick, viscous liquid, containing a large amount of dissolved sugars (60 to 65% brix), but showing little tendency for crystallization of dissolved sugar. The main use of these concentrated sweet fruit flavorings is as a base for cocktails, fruit cups or mixed with soda water as a long drink. Some examples of syrup are orgeat (almond), cassis (blackcurrant), citronelle (lemon), framboise (raspberry), cerise (cherry), Grenadine (Pomegranate) etc.

Service: Prepared drinks are served in highball/Tom Collins. Straw holder is placed on the table.

Squash: Squash is a  highly-sweetened and concentrated pulp of fruits, which is diluted with a liquid, most commonly water, before drinking. Typically, squash is created by mixing one part concentrate with four or five parts of water (depending on concentration and personal taste) directly into a glass or mug or into a jug. Squashes are also mixed with spirits or cocktails. The most common flavours are orange, apple and blackcurrant, lemon, peppermint, mixed fruit, summer fruits, and lemon-lime. Other flavours include peach, strawberry, passion fruit, custard apple and kiwi fruit.

Service: While taking order for squash, guest’s preference of mix should be noted. For example, a guest may prefer orange squash with soda.

Items to be carried to the table on a salver:

ü  Measured quantity of required squash in 12oz. beer goblet/highball/Tom Collins.
