Question: Is Guinness Beer Gluten Free?

Guinness Stout Beer

Unfortunately, like most beers and ales – Guinness is not gluten-free. It is brewed from barley, which is also roasted to give it its famous dark colour. Barley contains ‘gliadin’, a component found in gluten, which triggers inflammation in the small intestines.

Nutritional Information:

A 12-ounce serving of Guinness sets you back 125 calories—just 15 more than the same serving of Bud Light. Alcohol is beer’s main calorie source, and since Guinness is just 4.2% ABV, it’s relatively low in calories.

Most beers are carbonated with carbon dioxide, but Guinness uses a mix of CO2 and nitrogen.

Guinness stout is made from water, barley, roast malt extract, hops, and brewer’s yeast. A portion of the barley is roasted to give Guinness its dark colour and characteristic taste. It is pasteurised and filtered.
