They are typically 225, 336, 460, and sometimes 570 ml
You mean “They are typically 225, 336, 460, and sometimes 570 ml.[1]^”? I agree, it is dubious - it’s like someone assumed the whole world makes coffee in 8, 12, and 16oz. Also, they’re just below the “cup holding 50−100 ml” for espresso and “cup holding approximately 160 ml” for cappuccino.
dubious – discuss ↩︎










…I think I understand the source of the confusion here.
You think 8-12-16oz is the standard in coffee shops worldwide, because to you, “coffee” means “latte”, and “coffee shop” means “place that sells latte in plastic to-go cups”, whereas the standard unit of coffee in Europe is a café espresso, which is a 30ml shot of pure coffee served in a 50-100ml white china demitasse.
