Is Guinness Zero good for you? What the label says
By the Stout Guide team · Updated
What is in it
Water, barley malt, barley, roasted barley, fructose, natural flavourings, nitrogen and hops, per the label. It contains barley, so it is not gluten-free.
Compared with normal Guinness
Guinness Draught has 35 kcal per 100ml and about 4.2% alcohol. Guinness Zero has 17 kcal and 0.0% alcohol. Guinness brews it the same way, from water, barley, hops and yeast, then removes the alcohol by cold filtration.
What the health bodies say
Drinkaware says swapping a normal beer for an alcohol-free one cuts your alcohol, but only if it replaces the drink rather than adding to it. It also warns that alcohol-free does not automatically mean low calorie, so read the label. On that test Guinness 0.0 does well: 17 kcal per 100ml is lighter than many alcohol-free lagers.
