Gulden Draak Barrel Aged Calvados is the second in the series of Gulden Draak Quad barrel aged beers. The brewer ages Gulden Draak Quad 9000 in Calvados (Apple Cider Brandy) barrels for roughly 4-6 months. An ideal length of time for the residual flavors of the barrels to meld with the beer. This is a beer unlike any you've ever tasted. Once again, Jef Versele from Brewery Van Steenberge, produces a gem for all to enjoy. Cheers!
