A generic form of flavored beer, some breweries actually use real fruit or veggies, though most use an extract, syrup or processed flavor to give the effect of a particular fruit or vegetable.
Usually ales, but with not much ale character to them and commonly unbalanced.
Malt flavor is typically hidden with a low hop bitterness to allow the fruit or vegetable to dominate. Special type of fruit beers is Fruit lambics, which are usually bottled with secondary fermentation.
Although fruit lambics are among the most famous Belgian fruit beers, the use of names such as kriek, framboise or frambozen, cassis, etc. does not necessarily imply that the beer is made from lambic.
