Is Guinness safe to drink on a wheat free diet?

This is what the Guinness website lists for ingredients (04/19/2023):

"Our key ingredients - other than inspiration - are roasted barley, malted barley, hops, yeast, and water."

Important: this does not guarantee that it's wheat free due to cross-contamination when the barley is milled, and as it is brewed from barley malt it contains gluten which makes it unsuitable for celiac disease sufferers.

See the wheat & gluten free beer page for more information on wheat free, gluten free, and gluten reduced beers available...
