I have encountered something called Island Stout made by Coldfire and Buoy. It uses lager yeast. Is this a stout or a dark flavoured lager?
They are trying to mimic Caribbean stouts, which can be brewed with lager yeast - so… a tropical stout style-wise… put it under Stout - Extra / Foreign / Tropical and tag it as tropical stout I reckon.
Now the annoying thing is that we don’t know where it’s brewed. Coldfire has it as Buoy x Coldfire… and mentions that Buoy’s yeast was used, which kinda leans towards Buoy - but that’s no solid evidence.
Island Stout by Coldfire and Buoy is likely a stout, even though it uses lager yeast. Stouts can come in a variety of styles and can be brewed using different yeast strains, including lager yeast. The term “stout” refers to the color and body of the beer, which is typically dark and full-bodied, rather than the yeast used in brewing it. So, the final product should be judged by its flavor profile and appearance, which would generally be that of a stout, rather than the yeast used to make it.
