What is a Fruity Lambic?
Fruity Lambic is a variety of Lambic often produced like Gueuze Lambic—by mixin one, two and three year old Lambics in the same bottle. Fruit is added halfway the aging process, so the yeast and the bacteria can ferment all the sugars from the fruit. Most traditional styles of fruit lambic are kriek (with cherries), framboise (with raspberries) and druivenlambik (with muscat grapes). The flavour of the fruit should be evident, coming in hand with a sour flavour. When young, the beer preserves its fruity taste, but when aged the lambic character becames more dominant.
Wild ales with spontaneous fermentation are a typical brew from the area around Brussels—the Senne Valley. This style is just produced in that area due to its particular microbiotic fauna. It comes from a tradition of centuries where farmhouses used to have their own brew, and sometimes mix is with fruits in order to have a wider variety of beers available.
