Draught examples often have a creamy, long-lasting head. Malt-dominated flavor, with subdued esters and just enough hop bitterness to prevent the beer from being cloyingly sweet. Caramel flavor from crystal malt medium to none. May have some diacetyl. Creamy, with low carbonation.
Body is medium- light, but full for the gravity.
These guidelines don't account for these recent commercial examples which would more accurately be described as bitters. Traditionally, these beers were dispensed via pumps, which forced air into the headspace of the cask, thus forcing the beer out. Though similar in gravity to ordinary bitter, the malt- hop balance is decidedly to the malt side. Note that the smoky character can be due to the yeast as often as to smoked or peat-kilned malt. Strongly smoky beers should be entered in the Smoked Beer category rather than here.
