The Meerts Tilquin series was made by fermenting fruit that had already been used once. The fruit was fermented for a period of 4 months in a blend of 80% 1 year old Meerts and 20% of a blend of different 2 year old lambics. Meerts (or March Beer) is a low strength lambic, which was originally produced with the weaker wort obtained from the rinsing of the grains. Unfiltered and unpasteurized, they are refermented in the bottle. There are 12 bottles with 6 different fruits: Pinot Gris, Pinot Noir, Riesling,Syrah, Roussanne and Airelle Sauvage.
