What’s the most imaginative beer you’ve ever sipped? For me, it’s probably Mangalitsa Pig Porter from Right Brain, brewed with cold-smoked pig heads. But brewers don’t have to go that far out there in order to capture the imagination. Goose Island’s newest release in its Fulton & Wood series is a perfect example. Gran Gâs, which translates to Spruce Goose in Swedish, is a Belgian golden strong ale brewed with lingonberries and Colorado spruce tips (which went into the kettle a mere 24 hours after being plucked from trees). Check out the above video to see how inspiration struck. The beer’s still available at Goose Island’s Clybourn Brewpub location through the end of the month, so swing by and give it a try.
