Wine is an alcoholic beverage. The word wine in and of itself is defined as the produce by the fermentation of the juice of grapes - grapes are naturally, chemically balanced to normally ferment completely without requiring extra sugars, acids, enzymes or other nutrients. Other fruits such as apples, berries and blackcurrants are sometimes also fermented. These, however, are referred to as "apple wine" or "elderberry wine". Non-grape wines are called fruit wine or country wine. Other products made from starch-based materials, such as barley wine, rice wine (sake), are more similar to beers. The English word wine and its equivalents in other languages are protected by law in many jurisdictions. The word wine comes from the Old English win, which derives from the Proto-Germanic *winam, an early borrowing from the Latin vinum, "wine" or "(grape) vine" â€” itself derived from the Proto-Indo-European word *win-o (cf. Ancient Greek ????? oÃ®nos). Branches of Semitic languages have similar terms for grape/wine (S. Semitic & Arabic weyn, Hebrew yayin, Akkad. inu, proto-Semitic *wayn-) ; however, the exact relationship with the Indo-European words for vine is disputed. It is generally agreed to have been an early wanderwort . Both Hebrew and Arabic have a separate word for grape - enba/inab which is cognate with fruit in other semitic languages, e.g. Akkadian inbu, Syriac enba; and the choice of translation for the Hebrew yayin as grape may have been as a result of scholars influenced by the agenda of the temperance movement.
