Brandy, in general, refers to any kind of distilled spirit made from
fermented fruit juice.
The fruit in question is often grapes (see:
Wine), but there are a number of Brandies based on
apples, pears and other sweet fruits.
While most brandies are Wine-based—
Spanish Brandy and
Armenian Brandy are good examples—don't count fruit brandies out. They've got a few tasty surprises up their sleeve.
