"F" in wine glossary
The main component of the wine, usually grape but other fruits are also used to make wine, such as pear, plum, etc. Often mentioned when the fruit isn't grown in the same site as the winery, such as "the wine is produced here on-site, but the fruit is purchased from a vineyard upstate."
A fermented alcoholic beverage made from non-grape fruit juice which may or may not include the addition of sugar or honey. Fruit wines are always called "something" wines (e.g., plum wine), since the word wine alone is often legally defined as a beverage made only from grapes.
