For the second time this year, Allagash Brewing Co. will be releasing Coolship Red.

First released in 2011, the beer is a 6.2 percent ABV wild ale that is aged in French oak wine barrels for over two years before being conditioned on raspberries for “an additional four-to-five months.” The bottles being sold this weekend are from the same batch that were released earlier this year.

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.

Allagash has released eight different bottled beers that are produced using its coolship:

  • Coolship Red (6.2 percent ABV)
  • Coolship Resurgam (6 percent ABV)
  • Coolship Cerise (8.1 percent ABV)
  • Ghoulschip (6.9 percent ABV)
  • Coolship Balaton (5.9 percent ABV)
  • Coolship Single Barrel One (8.1 percent ABV)
  • Coolship La Mûre (7.7 percent ABV)
  • Coolship Clermont (6.6 percent ABV)

According to a post on Allagash’s Facebook page, the newest incarnation of Coolship Red will be packaged in 375ml bottles ($17) with no purchase limit when it goes on sale at the brewery on Aug. 26.
