Heavy Seas Beer announced the upcoming release of another new beer out of its limited 15 Barrel Brewhouse Series.

The new beer, Spectrology Sour, is a tropical sour ale brewed with pineapple, passion fruit, and mango purees. The beer will clock in at 8 percent ABV, will feature artwork from local artist Chris Shiner, and will be packaged in four-packs of 16-ounce cans for sale at the brewery via curbside sales on April 30.

This beer will join Bottomless Bellini, a beer which the brewery had released last February as well as the more recent Joose Cannon Lemon Meringue which came out in March.
