BJCP 13D
A very dark, moderately strong, roasty ale. Tropical varieties can be quite sweet, while export versions can be drier and fairly robust.
A rather broad class of stouts, these can be either fruity and sweet, dry and bitter, or even tinged with Brettanomyces (e.g., Guinness Foreign Extra Stout; this type of beer is best entered as a Specialty Beer – Category 23). Think of the style as either a scaled-up dry and/or sweet stout, or a scaled-down Imperial stout without the late hops. Highly bitter and hoppy versions are best entered as American-style Stouts (13E).
Lion Stout (Sri Lanka), Dragon Stout (Jamaica), ABC Stout (Singapore), Royal Extra "The Lion Stout" (Trinidad), Jamaica Stout (Jamaica), Export-Type: Freeminer Deep Shaft Stout, Guinness Foreign Extra Stout (bottled, not sold in the US), Ridgeway of Oxfordshire Foreign Extra Stout, Coopers Best Extra Stout, Elysian Dragonstooth Stout
