Lambic - geuze beersel, belgium. the golden blend is made with 25% four year old lambic and a "secret" combination of 1, 2, and 3 year old lambic. due to evaporation in the barrel, only a small percentage of the lambic is left over after 4 years of maturing. what is left has a profound and intensely concentrated flavor profile..
