Fermented beverages
Fruit juices which have undergone alcoholicfermentation by yeasts include wine, champaigne,port, sherry, tokay, muscat, Perry, orange wine, berrywine, nira and cider.
. Wine - are mostly made from grapes, but nowadaysany fruits in season like pineapple, mango etc., is alsobeing made into wine. Wine makers crushed the fruitand then ferment the juice. Wine is aged for 4 years orlonger. Most wine has an alcohol content of 8% to 20%.
Wine may be red or white or rose (pink). It can also besweet or dry( unsweet ). It can be served chilled or atroom temperature.

Unfermented beverages
Fruit juices which do not undergo alcoholic fermentationare termed as unfermented beverages. They includenatural and sweetened juices, RTS, nectar, cordial(Squash(drink), an extremely sweet non-alcoholic fruit flavoureddrink concentrate that is diluted with water to taste,popular in the UK, France, Australia, India, New Zealandand South Africa.), squash, crush, syrup, fruit juiceconcentrate and fruit juice powder. Barley waters(Barleywater, usually flavoured with lemon or other fruit, is atraditional Britishsoft drink. It is made by boiling
washed pearl barley, straining, then pouring the hot waterover the rind and/or pulp of the fruit, and adding fruit juiceand sugar to taste) and carbonated beverages are alsoincluded in this group.

FRUITBEVERAGE
SQUASH
This is a type of fruit beveragecontaining at least 25 per cent fruit juiceor pulp and 40 to 50 per cent total
soluble solids, commercially. It alsocontains about 1.0per cent acid and 350ppm sulphur dioxide or 600 ppmsodium benzoate. It is diluted beforeserving.
Mango, orange and pineapple are used
for making squash commercially. It canalso be prepared from lemon, bael,papaya, etc. using potassiummetabisulphite (KMS) as preservative orfrom jamun, passion-fruit, peach, plum,raspberry, strawberry, grapefruit, etc.
with sodium benzoate as preservative.

READY-TO-SERVE (RTS)
This is a type of fruit beverage which contains
at least 10 per cent fruit juice and 10 per cent
total soluble solids besides about 0.3 per cent
acid. It is not diluted before serving, hence it is
known as ready-to-serve (RTS).

FOR PREPARING THE ABOVE BEVERAGES, THE TOTAL SOLUBLE SOLIDS AND
TOTAL ACID PRESENT IN THE PULP/JUICE ARE FIRST DETERMINED AND THEN
THE REQUISITE AMOUNTS OF SUGAR AND CITRIC ACID DISSOLVED IN WATER
ARE ADDED FOR ADJUSTMENT OF TSS AND ACIDITY.
