Wine is an alcoholic beverage made from fermented grape juice. Wines made from other fruits are always named accordingly. The chemical composition of wine is about 87.7% water, 11% alcohol, 1% acid, and 0.2% tannins. Wine is any fermented fruit juice. People typically associate wine solely with grapes and it's true that the vast majority of all wine that you'll find almost anywhere is fermented grape juice, but wine can technically be made from other fruits like blueberries, raspberries, and strawberries.
