Imperial Stout aged in bourbon barrels with walnuts, pistachios, cassia bark & honey
aged in bourbon barrels; 16.9 oz bottle; Chicagoland only; allergens wheat and tree nuts; tasting notes of caramelized honeycomb, baking spice and roasted candied nuts
Goose Island says the recipe came from brewer Colby Magratten, inspired by the beehives on her aunt's Rhode Island homestead and by homemade baklava. On its page, the toasted nuts "highlight its warm, nutty character; cinnamon enhances the spice of the bourbon barrel," and the honey "deepens the stout's caramelized body" (Goose Island). A trade report on the 2025 lineup describes the same beer as inspired by baklava, combining toasted pistachios, walnuts and cinnamon (Beverage Information Group). The hops line reads "Millenium/Alchemy"; no malts or yeast are named.
As category context only, the Brewers Association guideline for Dessert or Pastry Beer describes beers that "build on a strong dark beer base and incorporate culinary ingredients," deep amber to black, at 5.5 to 10.25 percent ABV or more and 20 to 65 IBU. A 13.9% imperial stout with nuts, spice and honey fits the open ended upper ABV range and the culinary intent.
