Very dark with a slight tan head. Excellent rich roasty aroma. Light to medium body with nice carbonation. This beer has a very unusual and surprisingly flavour. The aroma and appearance lines up you expectations for a rich velvety stout or similar, but the foretaste is sour, in the best possible way, but it’s a sour beer initially. The richer sweeter dark malt flavours then steadily develop in a way that complements the sourness wonderfully. The is a coffeeish bitterness in the finish. Overall this is a very unusual and clever beer that works very well. The mix of two styles, and the surprise value of the mismatch between initial taste and aroma and appearance is great.
