Gueuze (or Geuze)

Geuze is a type of lambic, a Belgian beer, made by blending young (1 year old) and old (2–3 year old) lambics into a new beer which is then bottled for a second fermentation. Because the young beer is not fully fermented, it contains fermentable sugars, which allow the second fermentation to occur.

Since gueuze is made by blending lambics, it tastes different from traditional ale and pilsner style beers, and because aged hops are used to produce these lambics, the beer has little to none of the traditional hop bitterness that can be found in most other styles of beer.

Many describe the taste as sour however some brewers add sugar to make the beer more appealing to a wider audience.

Due to it's carbonation, gueuze is sometimes called 'Brussels Champagne'.
