Lowest Calorie Alcohol-Free Beer UK 2026: Fact-Checked & Ranked

Fact-checked October 2026 · by Rich, founder of Unhopped

A low calorie count doesn’t have to mean giving up great beer. But there’s a lot of confused information out there — so we’ve fact-checked the numbers from brewery and nutrition sources, and, crucially, put every figure on the same basis so you can actually compare them.

The lowest calorie alcohol-free beers, ranked

Ranked by calories per 100ml — the only fair comparison when packs run from a 330ml can to a 568ml pint can — with the per-pack figure alongside, since that’s what you actually get when you crack one open. Beers on the same per-100ml figure share a place. All figures checked against brewers’ and retailers’ nutrition labels in October 2026.

Full comparison table

Every beer we list at 10 kcal per 100ml or less, lowest first, followed by some familiar names for comparison. We’ve shown per 100ml (the like-for-like number) and per pack (what’s actually in the can or bottle) side by side — so if you see a different figure quoted elsewhere, you can see exactly which basis it’s using.

The rest of the beers we have figures for run from 11 to 36 kcal per 100ml, with most between 15 and 25. One caveat: Poolside is no longer in Big Drop’s range, though Ocado still listed it when we checked.

Why alcohol-free beer is lower in calories

Most of the calories in regular beer come from the alcohol itself — pure alcohol carries about 7 kcal per gram, nearly double the 4 kcal/g in carbohydrate. Remove the alcohol and you remove its calories, which is why a 0.0% beer can undercut its full-strength version so dramatically. A pint of standard 5% lager runs 180–240 kcal; the AF equivalents here are a fraction of that.

One honest nuance: removing alcohol doesn’t take a beer to zero, because the calories left come from residual carbohydrates and malt sugars. That’s why the beers we list run from 3 to 36 kcal per 100ml rather than sitting at nothing — and why the recipe matters as much as the strength.

Lowest calorie by style

Pale ale: BrewDog Nanny State at 6 kcal per 100ml (about 20 kcal per 330ml can) has the fewest calories of the pale ales we list, though it wasn’t on sale when we checked in October 2026.
IPA: Big Drop Paradiso Citra IPA at 3 kcal per 100ml (11 kcal per 330ml can) has the fewest calories of any beer we list, full stop; UNLTD. IPA follows at 4 kcal per 100ml (23 kcal per 568ml pint can); Athletic Run Wild is the benchmark for taste at 17 kcal per 100ml, or 65 kcal per 355ml can.
Lager: Big Drop Reef Point leads at 4 kcal per 100ml, with Athletic Lager and UNLTD. Lager both at 7 kcal per 100ml. Heineken 0.0 is 21 kcal per 100ml (about 69 kcal per 330ml).
Stout: Guinness 0.0 at 17 kcal per 100ml (75 kcal per 440ml can) ties with Drop Bear Bonfire and Brulo Cascadian Tides for the fewest calories among the stouts we list — impressive for a stout with that much body.
Hazy IPA: Firebrand Shorebreak, at about 7.3 kcal per 100ml (Firebrand gives 32 kcal a 440ml can), has the fewest calories of the hazy IPAs we list; Athletic Free Wave has more, at 19 kcal per 100ml (about 67 kcal per 355ml can).
Wheat beer: La Chouffe 0.0, a Belgian blonde we file with our wheat beers, has the fewest calories of those we list, at 13 kcal per 100ml; of the wheat beers proper, Kapuziner Weissbier has the fewest, at 17 kcal per 100ml (85 kcal per 500ml).

Keeping it light: what to pair

If you like your beer light, it’s worth thinking about what’s alongside it too. Lighter snacks like seaweed thins or biltong make a good match for a light, crisp beer — and our best 0.0% beers guide covers the ones worth drinking on taste alone, calories aside.
