Stillwater Artisanal Ales and Buxton are combining forces on not just one, but two new beers.

The two new beers are Subliminal, a 10 percent ABV “chewy” imperial stout, and Superluminal, a 7 percent ABV sour IPA brewed with citra, Mosaic and Simcoe hops. According to Stillwater owner Brian Strumke, both beers are part of what will “most likely” be an ongoing series of collaborations brewed at Buxton Brewery in Buxton, U.K.

In an email, Strumke told Tenemu that both Subluminal and Superluminal will be packaged in 11.2-ounce bottles that are scheduled to ship across the company’s full distribution network in “limited” qualities in March.
