A standard glass of red or white wine (175ml) with 13% ABV could also contain up to 160 calories, similar to a slice of Madeira cake. Often when sharing wine, we assume we’re drinking less calories but a bottle of 13% ABV wine shared between two could mean you are consuming 340 calories each, that’s the equivalent of a chocolate croissant each.
