I wonder if there is something else in Guiness that is also an allergen for you.We proved it does, very, very painfully.
It's a sugar created as part of the process, and since it's not derived from dairy.......
Lactose is added to pills as a filler, and some luncheon meats as a sweetener.
Ales, pilsners, IPAs, all work fine though !
Was it bottle or tap? Some bars don't have the best cleanliness.
