Old Ales, also referred to in the past as "Stock" Ales, are low attenuated beers with high levels of dextrins, creating a full malt body with plenty of character. Old Ales of a hundred plus years ago were often transfered into vats to mature, hence the name.
Rich dark amber in color to a very dark brown; near black. Tamed aromatics. Although bittering levels can greatly vary, expect common fruity, vinous, intense malts and sharp alcohol characteristics. The often racy but mellow attitude of the beer may also include acidic notes, raisins and black currants. Vintage varieties may have a low level of oxidation. Stronger versions may have similarities to a port wine. Brewers may also inoculate a portion of the batch with Brettanomyces lambicus and age for an extended period of time to achieve an old-school acidic character.
