Columbia’s Swamp Cabbage Brewing Co. will hold its first bottle release event this Saturday, Oct. 24, for a collaboration stout to benefit cystic fibrosis research.

Swamp Cabbage recently partnered with Columbia’s Brewsky Brothers to brew up a 7.5% Chocolate Covered Pretzel Stout, which will be the first beer the brewery has ever packaged. The release will be limited to 200 bottles at $15 a pop, with proceeds going directly to support the South Carolina chapter of the Cystic Fibrosis Foundation. (The beer will also be on tap at the brewery.) A silent auction is also planned to support the charity, and food vendors on site that day will also be donating a portion of their sales to the foundation.
