A fairly substantial English dark ale with restrained roasty characteristics.
Differs from a robust porter in that it usually has softer, sweeter and more caramelly flavors, lower gravities, and usually less alcohol. More substance and roast than a brown ale. Higher in gravity than a dark mild. Some versions are fermented with lager yeast. Balance tends toward malt more than hops. Usually has an "English" character. Historical versions with Brettanomyces, sourness, or smokiness should be entered in the Specialty Beer category (23).
