Infusion B -- which clocks in at 8.2 percent alcohol by volume -- is Mean Manalishi infused with Citra and Cascade hops. It’s part of the new Tower Tuesday Series of small-batch beers available exclusively at the Hoppin’ Frog Tasting Room. The series is an offshoot of the brewery’s popular Tower Tuesdays program, in which beers are run through a giant tower filled with various ingredients that infuse the beer with new flavors.
