How is Lambic fruit beer traditionally made? There are a few fruit beers around how are these traditionally made?  I know they are all Lambics, but how are they made exactly?
Lambic is a type of beer brewed in the Pajottenland region of Belgium and in Brussels itself at the Cantillon Brewery and museum. Lambic beer is produced by spontaneous fermentation: it is exposed to the wild yeasts and bacteria native to the Zenne valley. This gives the beer a dry, vinous, and cidery taste, usually with a sour aftertaste.

This beer forms the basis of the Lambic fruit beers. After the Lambic is made, fruit juice is added to the barrels right before bottleing the beer.
