Maple Bourbon barrel aged Imperial Stout and barley wine blend.
Evil Twin started by brewing their famous Michigan Maple Jesus (in Massachusetts though, so maybe we should call it Massachusetts Maple Jesus). Same Recipe, same bourbon maple syrup barrels from BliS, but even longer aging- 21 month did the beer spend in the barrels soaking up flavors of wood, maple syrup and bourbon.
After the 21 months, they brewed a big English style barley wine and blended it with the Massachusetts Maple Jesus to create a new style they call Grand Cru. Think flavors of roasted malt, tobacco, sweetness from the syrup, lots of wood, figs, prunes, toffee, and cocoa.
Evil Twin was started in Denmark in 2010 and is now based in Brooklyn, NY. It brews at ten different breweries in six different countries and is a consistent innovator in the beer world.
