"Riserva is an American Wild Ale fermented on red raspberries. Riserva is fermented with a blend of Saccharomyces yeast, Brettanomyces yeast and lactic acid bacteria that produce funky, sour and fruity flavors and aromas. The beer is aged for more than a year in oak barrels with raspberries, giving the beer a pungent raspberry aroma, a lovely red color and a balancing wood character. This brew is a beautiful beer both to your eyes and to your taste buds. The microflora responsible for giving Riserva its character reside in the wood barrels and change somewhat over time depending upon factors such as the age of the barrel and the ambient temperature at which the barrels are stored. New barrels are rotated into the mix as old barrels are rotated out and as such, Riserva varies somewhat in color and tartness from year to year. Riserva is much higher in alcohol than its Belgian lambic framboise cousins and is a true treat to experience."
