Wine:Fermentation of juices for the preparation of alcoholic beverages is being practiced for the last many centuries. Wine is a fermented beverages produced from grape and has a large acceptability across the world and has immense potential for local marketing as well as export. Product made by alcoholic fermentation of grapes or grape juice unless otherwise specified, by yeast (Saccharomyces cerevisiae) and a subsequent ageing process. Alcohol content is 11-14 %, but may be as low as 7 %.
During Fermentation:-Yeast Saccharomyces cerevisae, which causes fermentation, is a single cell organism that converts the sugar in the fruit to alcohol and carbon dioxide. The carbon dioxide escapes into the air and what is left is wine.
Reaction:-
Types: 1. Red wine 2. White wine
In wine making the temperature cannot exced:29.4 °C – red wines15.3 °C – white wines

Extract the flavor and aroma from the bast ingredients by chopping, crushing, pressing
Add sugar, acid, nutrients, and yeast to the fementation media
press off the liquid from the pulp, put it into a secondary fermentation vessel and allow fermentation after several weeks
When wine is clear and all fermentation has stopped, siphon into wine bottles and cork the bottles securely
