The Salopian Brewing Company is in Shrewsbury, Shropshire, U.K. According to the bottle "entire butt" is historically the term used to describe a porter that is blended from a variety of ales. This beer uses 14 different malts including barley, wheat and oats. 4.2% ABV.
This beer pours very dark brown to black. It is well carbonated in the way that many bottle conditioned beers are. The aroma is of dark roasted malt, coffee, dark chocolate, a bit of sweetness and also some sour notes, probably from the yeast. The taste is deep, rich, dark, lots of coffee, some dark chocolate, not at all overly sweet (as too many American porters are) and has a nice dry, bitter finish. The mouthfeel is very smooth, perhaps due to the oats. This is an absolutely excellent porter.
