Northern 017 Agent Contains Nuts

It might not be an obvious combination of flavors, but the careful balance between mango and peanut butter creates enough opposites to bring out both flavors. The acidity of the mango cuts through the roasted fatness of the peanut, and its sweetness harmonizes with the salty umami character of the nut. It is based on a Kweik & Idaho 7 Pale Ale, which is acidified with mango puree before it is expanded with peanuts and vanilla to create a brilliantly complex, but very tasty sour beer.
