One of Allagash Brewing Co.’s most anticipated seasonal releases is returning next weekend.
Coolship Red 2018 is a 6.7 percent ABV spontaneously fermented coolship ale that has aged in French oak wine barrels before being conditioned on raspberries from Maine. The fruited sour beer debuted in 2011 and was released twice last year in April and August, although both releases came in at a slightly lower 6.2 percent ABV.
A koelschip—or coolship, as it is more commonly known in America—is a large, shallow steel pan about a foot deep that is used to both cool down wort after it is brewed and to expose the resulting concoction to naturally occurring yeasts and bacteria that are in the air. A number of U.S.-based breweries incorporate coolship beers into their lineups, including Jester King Brewery, Allagash and The Collective Brewing Project.
According to a post on Allagash’s Instagram page, Coolship Red 2018 will be packaged in 375ml bottles and will have no bottle limits when it is released exclusively at the brewery on May 19.
