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

process. Alcohol content is 11-14 %, but may be as low
as 7 %.

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:-

5. Types:
1. Red wine
2. White wine
In wine making the temperature cannot exced:
29.4 °C – red wines
15.3 °C – white wines

6. Nutritional value of wine
Nutritional value per 100 g
Energy 355 kJ (85 kcal)
Carbohydrates 2.6 g

Fat 0.0 g
Protein 0.1 g
Alcohol 10.6 g

7. 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
