Bartlett Blueberry Wine

[Hal]

Although all the wine I drink is made from grapes, wine can be made from other fruits. Because most wine is made from grapes, and most people associate the word wine with grapes, it is customary usage when refering to wine not made from grapes to specify the fruit source. So when we hear 'wine', we understand that it's wine made from grapes. But when we hear 'blueberry wine' we understand it's wine not made from grapes.

From The American Heritage® Dictionary of the English Language: Fourth Edition:

wine NOUN: 1a. A beverage made of the fermented juice of any of various kinds of grapes, usually containing from 10 to 15 percent alcohol by volume. b. A beverage made of the fermented juice of any of various other fruits or plants. 2. Something that intoxicates or exhilarates. 3. The color of red wine.

Yes, the first definition specifies grapes, but it is not the only definition. It is clear that wine is not made only from grapes.
