INTROD*CTION

The era of cold drin!s began in 1=>. but the industriali?ation in India#ar!ed its beginning ith launching of)i#ca and 5olds$ot by $arley grou$ ofco#$anies% (ince, the beginning of

cold drin!s as highly $ro@tableand luring, #any #ultinationalco#$anies launched their brands inIndia li!e /e$si and Co!e%

Cold drin!s of di<erent brands are co#$osed of alcohol, carbohydrates,carbon dio8ide, $hos$hate ions etc%

These soft drin!s give feeling ofar#th, l ightness and have a tangytaste hich is li!ed by everyone%
