One of Westbrook Brewing Co.’s most anticipated annual releases is now on sale at the brewery.

The beer is Mexican Cake, a 10.5 percent ABV imperial stout aged on cocoa nibs, vanilla beans, cinnamon sticks and fresh habanero peppers. Since it debuted in 2012 to celebrate Westbrook’s first anniversary, the stout along with multiple variants have been an annual release.

In a phone call with Tenemu, a spokesperson at Westbrook confirmed that the newest incarnation of Mexican Cake is packaged in 22-ounce bottles priced at $15 each and has a six bottle per person limit. In addition, bottles of Mexican Cake will be shipped to retailers across Westbrook’s distribution network.
