Colley's Dog (5.2%) from Tring Brewery,Hertfordshire.
Dark ruby in colour but not over rich. Strong yet very drinkable, this premium ale has a long dry finish with overtones of malt and walnuts.
Maybe not a session Beer as it is fairly strong.
A close second was Guerilla (4.9%) from Blue Monkey Brewery, Notts.
Both these Beers were available last Friday @ 'The Wellington', Bennett's Hill,Brum,which is a specialist Real Ale Pub.
