Does non-alcoholic beer have alcohol?
Short answer: usually a tiny bit. In Australia a beer can be sold as "non-alcoholic" while still containing up to 0.5% alcohol by volume — a trace amount on par with ripe fruit or fresh orange juice. Here's what the label really means, how it compares to a standard drink, and what it means for driving and pregnancy.
What "non-alcoholic" actually means
The zero and low-alcohol beer shelf has exploded in the last few years, and the wording on the cans can be confusing. In Australia the key number is 0.5% ABV (alcohol by volume). Under Food Standards Australia New Zealand rules, a drink only has to declare its alcohol content and standard drinks once it goes above 0.5% ABV, so 0.5% has become the working line between "non-alcoholic" and everything stronger.
That gives you a few tiers on the shelf:
- 0.0% — no measurable alcohol. The safest choice if you need to avoid alcohol entirely.
- Non-alcoholic / alcohol-free (up to 0.5% ABV) — a trace amount, often left over from the brewing process rather than added.
- Low-alcohol / light (roughly 0.5%–1.15% ABV) — a small but real amount; these must state their standard drinks on the label.
- Mid and full-strength beer (about 3.5%–5%+ ABV) — ordinary alcoholic beer.
Words like "alcohol-free" and "zero" aren't tightly policed, so brands use them loosely. As Western Australia's health department guidance notes, any drink above 0.5% ABV must carry an alcohol statement — so the number on the can tells you more than the marketing around it. If you need genuine zero, look for 0.0% specifically.
Where does the leftover alcohol come from?
Most non-alcoholic beer starts life as ordinary beer. Brewers then either remove the alcohol (through gentle heating or filtration) or brew in a way that produces very little in the first place. Either way, a small amount of alcohol can remain — which is why so many products land just under the 0.5% mark rather than at a perfect zero.
To put 0.5% in context, it's a level you already meet in everyday foods. Fresh orange juice, very ripe bananas, yeast-risen breads, kombucha and some soy sauces and vinegars all contain traces of alcohol from natural fermentation, sometimes in the same 0.1%–0.5% range. You wouldn't call a slice of rye toast a drink — and a 0.5% beer is in similar territory.
How it compares to a real beer
An Australian standard drink contains 10 grams of pure alcohol. You can work out any drink's standard-drink count with a simple formula: volume (ml) × %ABV × 0.789 ÷ 1000. Run the numbers on a 0.5% beer and it barely registers.
| Drink | Serve | ABV | Standard drinks |
|---|---|---|---|
| Non-alcoholic beer (0.0%) | 375 ml can | 0.0% | ≈ 0 |
| Non-alcoholic beer | 375 ml can | 0.5% | ≈ 0.15 |
| Non-alcoholic beer | 500 ml can | 0.5% | ≈ 0.2 |
| Mid-strength beer | 375 ml can | 3.5% | ≈ 1.0 |
| Full-strength beer | 375 ml can | 4.8% | ≈ 1.4 |
In other words, a 375 ml can at 0.5% is only about a seventh of a standard drink — you'd need roughly seven of them to reach a single standard drink, and around ten to match one full-strength beer. For a full breakdown of the stronger stuff, see our guide to standard drinks in beer.
That's why non-alcoholic beer has become such a popular way to cut down without giving up the ritual. It also carries far fewer kilojoules than full-strength beer, and lets you have "one in your hand" at a barbecue or the footy without adding to your total.
Can you drive after non-alcoholic beer?
For a driver on a full licence with a 0.05 limit, a couple of 0.5% beers are very unlikely to move your blood alcohol anywhere near the limit. The amounts are so small that your body clears the alcohol about as fast as you absorb it, so it doesn't build up. Research testing people on 0.5% drinks has found no meaningful rise in blood alcohol content.
There are two things worth knowing, though. First, if you're on a learner or provisional licence — or driving a vehicle that requires a 0.00 reading — a genuine 0.0% product is the safer pick, since a trace is still a trace. Second, drinking anything leaves a little alcohol in your mouth for a few minutes, so a roadside screening test taken immediately after a sip can read momentarily high; this "mouth alcohol" clears quickly and the evidential test that follows measures deep-lung air. Our guide to the Australian drink-driving limits covers who has to be at zero.
Is it safe during pregnancy?
Australian health advice is that no amount of alcohol is known to be safe in pregnancy. Because a beer labelled "non-alcoholic" can still contain up to 0.5% ABV, it is not automatically alcohol-free. If you're pregnant or trying to conceive and want a beer-style drink, a product clearly marked 0.0% is the safest choice — and it's always worth checking the label and having a quick word with your doctor or midwife. The same caution applies to non-alcoholic wines and spirits, which can also sit just under the 0.5% line.
The bottom line
Non-alcoholic beer isn't a con — it just isn't always a perfect zero. Most contain a trace of alcohol up to 0.5% ABV, roughly a seventh of a standard drink per can and comparable to the alcohol in everyday foods. For most people cutting back or driving home on a full licence, that's negligible. If you need true zero — for a zero-limit licence, for pregnancy, or simply by choice — reach for a product that clearly says 0.0%. As the UK's Drinkaware puts it, the label wording and the actual figure aren't always the same thing — so it pays to read the number.
Frequently asked questions
Does non-alcoholic beer have alcohol in it?
Usually a tiny amount. In Australia a drink can be labelled non-alcoholic if it's 0.5% ABV or less. Some are genuinely 0.0%; many sit just under 0.5%, a trace similar to ripe fruit, orange juice or yeast bread.
How many non-alcoholic beers equal a standard drink?
A 375 ml can at 0.5% ABV is about 0.15 of a standard drink, so roughly seven of them add up to one standard drink. One full-strength beer holds about ten times the alcohol of a 0.5% one.
Can you drive after drinking non-alcoholic beer?
For full-licence drivers, a few 0.5% beers are very unlikely to reach the 0.05 limit because the body clears trace alcohol as fast as it's absorbed. Learner and provisional drivers must be at 0.00, so choose a 0.0% product. If you've also had real alcohol, only time lowers your BAC.
Is non-alcoholic beer safe during pregnancy?
No amount of alcohol is known to be safe in pregnancy, and non-alcoholic beer can still contain up to 0.5%. A clearly labelled 0.0% product is the safest choice — check the label and ask your doctor or midwife.
What's the difference between 0.0%, alcohol-free and non-alcoholic?
"0.0%" means no measurable alcohol. "Non-alcoholic" means 0.5% ABV or less, so it may contain a trace. "Alcohol-free" and "zero" are used loosely by brands, so trust the figure over the words.
