Producing a range of locally sourced Belgian-style brews, Darkside Fermentation is located in the storage room of “The Root Cellar Cafe in San Marcos.” It started when Brewer and owner, Silas Parker approached The Root Cellar’s owner, Kyle Mylius in May 2009 to sell Darkside beer in the cafe. They offer Darkside’s flagship beer, “Mark of the Yeast: 78666” which is referred to by Parker as a “dark medieval ale.” This beer is nourishing and the finish lingers. Other beers in the Darkside lineup include the draught beers BrideAle and GroomsBeer, Weiz Guy, Golden Mean, and Pale Rider, a Belgian pale ale. Come in and try some these great beer that are brewed in-house. They also have a lot of seasonal flavors to choose from.
