This fall, Evil Twin Brewing and Westbrook Brewing Co. will release a couple of barrel-aged variants of a previous collaboration.

The beers are Maple Bourbon Barrel Aged Imperial Mexican Biscotti Cake Break, a 10.5 percent ABV imperial stout brewed with almonds, cocoa nibs, coffee, cinnamon, habanero peppers and vanilla beans before being aged in maple bourbon barrels for 16 months and Double Barrel Aged Imperial Mexican Biscotti Cake Break, a 10.5 percent ABV imperial stout brewed with almonds, cocoa nibs, coffee, cinnamon, habanero peppers and vanilla beans before being aged in both maple bourbon barrels and Marsala wine barrels for 16 months.

As with the original version named Imperial Mexican Biscotti Cake Break (10.5 percent ABV) that was released last year, the two new incarnations are a combined recipe of one of each individual brewery’s more popular releases: Evil Twin’s Imperial Biscotti Break, an 11.5 percent ABV imperial stout brewed with almonds, coffee and vanilla that was first released in 2012, and Westbrook’s Mexican Cake, a 10.5 percent ABV imperial stout brewed with almonds, cocoa nibs, coffee, cinnamon sticks, fresh habanero peppers and vanilla beans that was first released in 2012.

In an email, Jeppe Jarnit-Bjergsø, owner of Evil Twin, told Tenemu that both Maple Bourbon Barrel Aged Imperial Mexican Biscotti Cake Break and Double Barrel Aged Imperial Mexican Biscotti Cake Break will be packaged in 22-ounce bottles that are scheduled to start shipping to the company’s entire distribution network in limited quantities in October or November.
