In addition to the Classic City Brew Fest this Sunday, two local breweries are celebrating their birthdays in April.

Terrapin celebrates its 17th anniversary with a carnival from 4:30–8:30 p.m. Saturday, Apr. 6 at the Newton Bridge Road brewery. In addition to year-round brews, the carnival features cask ales, barrel-aged beers, beers from Terrapin’s ATL Brew Lab at SunTrust Park and other special brews, along with entertainment from the Balkun Brothers band, local vendors, food trucks and games. Tickets, available at terrapinbeer.com, are $26 and include beer samples, a brewery tour and a souvenir glass. Proceeds will benefit Nuçi’s Space, a mental health and resource center for musicians.

On Saturday, Apr. 13, Creature Comforts will release a limited-edition Five Year Anniversary Ale—a blended 12.8% ABV ale aged in whiskey barrels for 23 months—at its Hancock Avenue brewery downtown. Other limited-edition beers that will be available include Existence (2019), Concurrence Blend No. 001, Duende and Athena Tiki (Painkiller). Creature Comforts’ fifth-anniversary celebration takes place Friday, Apr. 12 from 1–10 p.m. and Saturday, Apr. 13 from 1–11 p.m. Both days feature live music, headlined by Partials on Friday and New Madrid on Saturday.
