Drie Fonteinen Oude Geuze is a traditional Belgian lambic beer produced by Brouwerij 3 Fonteinen, located in Beersel, Belgium. This beer is a blend of one, two, and three-year-old lambics, which are spontaneously fermented beers made from a mixture of malted barley and unmalted wheat. The blending process is a meticulous art, resulting in a complex and balanced beer with a distinctive sour and tart flavor profile. The Oude Geuze is bottle-conditioned, allowing it to develop further complexity over time. It features notes of green apple, lemon zest, and a hint of barnyard funk, with a dry finish and lively carbonation. This beer is best enjoyed chilled and pairs well with sharp cheeses, seafood, and charcuterie.
