Sour Monkey Belgian Sour Tripel Beer, 12 fl oz, 6 Pack Bottles, 9.5% ABV. Tastefully tart is how our monkeys describe their sour sibling. Born from the same imported malts, Belgian yeast, and magical spices, this monkey decided to take a walk on the tangy side. With a swirling citrusy, lemon bite and a delectable essence, you better pucker up and respect this monkey. Belgian yeast swirl through a precise souring. Pucker up to a bite of citrus laden tang.
