Grape Juice for Wine Making

Grapes are a fruit or berry, which grows on the deciduous woody vines of the flowering plant genus Vitis.

By crushing and pulping grapes into a liquid grape juice is obtained. The fluid is often sold in packets or bottles in supermarkets, or it is fermented and made into wine, brandy, or vinegar.  Grape juice can also be pasteurised, which will remove any naturally occurring yeast, the resulting liquid will not ferment if kept sterile, and therefore contains no alcohol.  When making wine, grape juice that contains 7–23% of pulp, skins, stems and seeds is referred to as "must".
