The San Francisco-based brewery has released Barrel-Aged Plum Sournova, a 5.2 percent ABV sour ale aged in oak barrels and conditioned on real plums and vanilla beans.

Almanac has released a number of barrel-aged nova-themed beer before, including Barrel-Aged Raspberry Supernova, a sour ale conditioned on raspberries; and Barrel-Aged Strawberry Sournova, a 5.3 percent ABV sour ale aged in oak barrels and conditioned on real strawberries and vanilla beans.
