Maris Otter pale ale turned black. Lots of Citra hops. 5%. Velvety and hoppy. Available in bottles from Two Brews, Crouch Street, Colchester.
Oh, and a Black Otter is a dwarf rex rabbit from the Netherlands, and as the beer is based on Maris Otter malt, but is black and velvetty and hoppy, it seemed an appropriate name! #justsaying
