Notes


​Imperial Blueberry Stout | 11.5% ABV

​Profile: Scorched Malt · Dark Cacao · Nightwood Berries · Vinous Acidity

​The Story: Built on the grim discipline of the Karrnathi North. This 11.5% titan pours like ink, trading sweetness for the sharp, vinous acidity of berries harvested from the edge of the Nightwood. A beer of endurance—stoic, heavy, and engineered for the long winter watch.

​Serve cold. Stay sharp.




Used this for the blueberries. The blueberries increased the percentage of 10 to 11.53. So caution is advised.
