Dogfish Head Craft Brewery and The Veil Brewing Co. are joining forces on Knuckles, Bats and Homemade Tats, a 6.5 percent ABV sour ale brewed with a blend of locally grown and malted Violeta barley as well as the “ancient grains” Finkorn and Spelt before being aged in French oak Chardonnay barrels for 18 months. The ale was then refermented on “extravagant quantities” of hibiscus as well as red, white and black currants.

According to a label filed with the Alcohol and Tobacco Tax and Trade Bureau (TTB), Knuckles, Bats and Homemade Tats will be packaged in 12.7-ounce bottles.

An email sent to both breweries for additional information was not immediately returned.
