This weekend, Turning Point Beer is releasing its highest ABV creation so far.

Endgame is a 10-barrel batch of 15.4 percent ABV imperial stout aged in bourbon barrels for 12 months and conditioned on six gallons of cacao nibs and 11 pounds of Madagascar vanilla beans. This is only the second barrel-aged beer that the Bedford, Texas-based brewery has packaged, after Release The Krausen debuted last month.

According to a post on Turning Point’s Facebook page, Endgame will be packaged in 500ml waxed bottles ($16) and will not have a purchase limit when it goes on sale exclusively at the brewery on April 27.
