Slovak collaboration. Our friends from Voodoo Brewery came up with the idea of brewing a Black IPA with kola nuts and vanilla as part of our collaboration. We jumped at this concept, and the result is a strong yet sharp Black IPA. Its citrus notes, imparted by Motueka and Citra hops, are complemented by the distinctive aroma of kola nuts, giving the beer a flavour that truly evokes Coca-Cola.
