Short answer: usually a tiny bit, yes. In the US, a beer labeled “non-alcoholic” can legally contain up to 0.5% ABV, it just cannot be labeled “alcohol free” unless it is truly 0.0% ABV. Here is what that actually means in practice, and where to find NA beers that hit true zero if that matters for you.
The Legal Definitions
| “Non-alcoholic” (US) | Under 0.5% ABV, permitted by the TTB, no alcohol tolerance allowed |
| “Alcohol free” (US) | Must be 0.0% ABV exactly, and requires TTB sample approval to use the label |
| “Low alcohol” (US) | Describes beverages with lower-than-usual ABV, generally above 0.5% |
| EU/UK convention | Similarly split between 0.0% “alcohol-free” and up to roughly 0.5% “low/non-alcoholic” |
Why non-alcoholic beer isn’t always 0.0%
Labelling rules in this space keep evolving, the UK, for instance, has seen a petition pushing to tighten the 0.5% “alcohol-free” threshold, and US regulators have faced similar pressure over trace-alcohol labeling requirements for products marketed as alcohol-free.
Most non-alcoholic beer is brewed as normal beer, then has most of the alcohol removed afterward, usually through vacuum distillation or reverse osmosis, both of which pull ethanol out at low temperatures to avoid cooking off the flavor compounds. We cover the full process in how non-alcoholic beer is actually made, but the short version is that the process is very good but not perfect, which is why the finished product almost always retains a trace amount of alcohol, typically well under 0.5% ABV.
A smaller number of non-alcoholic beers are brewed specifically to stop fermentation early or use a modified process that never produces meaningful alcohol in the first place, and those can more reliably hit 0.0%. If you want a drink that guarantees zero ethanol by design rather than by extraction, hop water is worth a look, it is brewed without any fermentation step at all.
Is 0.5% ABV actually a problem?
For almost everyone, no. A 0.5% ABV beer contains a fraction of the alcohol found in a ripe banana or a slice of bread made with yeast, both of which naturally produce trace ethanol during normal ripening or baking. You would need to drink many non-alcoholic beers in a short window to register any detectable blood alcohol content. For context on how that compares across styles, see our breakdown of beer alcohol percentage by style.
The exceptions are people who need to avoid alcohol entirely for medical reasons, those in recovery from alcohol use disorder, and pregnant people following an abstinence-only recommendation. We go deeper on that specific question in can you drink non-alcoholic beer while pregnant, for those groups, checking for a true 0.0% “alcohol free” label rather than “non-alcoholic” is the safer call.
How to tell which one you’re buying
Check the label wording carefully rather than assuming. “Alcohol free” or “0.0%” means genuinely zero, Heineken 0.0 is the most widely available example and is brewed to hit true zero by design. “Non-alcoholic,” “NA,” or “near beer” generally means under 0.5% ABV but not necessarily zero. If the can does not state a specific ABV, that is usually a sign it falls in the under-0.5% category rather than true zero.
Our BrewDog Non-Alcoholic Beer review and our roundup of the best non-alcoholic Oktoberfest beers both note the exact ABV on the label for this reason, it is worth checking brand by brand rather than assuming every NA beer behaves the same way.
“Finished beverages containing less than 0.5% ABV are not considered alcohol beverages under federal regulations.”, US Alcohol and Tobacco Tax and Trade Bureau (TTB)
More brands keep entering the true-zero category too, Old Speckled Hen’s zero-alcohol launch is a recent example of a legacy ale brand adding a genuine 0.0% option. Pricing is worth watching too, our look at non-alcoholic beer price psychology covers why NA beers are often priced close to their alcoholic counterparts despite skipping the alcohol.
FAQs
Can non-alcoholic beer get you drunk?
Practically speaking, no. At under 0.5% ABV, you would need to drink an unrealistic volume in a short period to register any measurable blood alcohol content.
Is 0.0% the same as non-alcoholic?
Not necessarily. “Non-alcoholic” legally allows up to 0.5% ABV in the US, while “alcohol free” must be exactly 0.0% ABV.
Why does non-alcoholic beer still have some alcohol?
Most non-alcoholic beer starts as regular beer and has alcohol removed afterward through methods like vacuum distillation, which are highly effective but rarely remove every last trace of ethanol.
Should pregnant people avoid non-alcoholic beer?
Many health guidelines recommend choosing a beer labeled “alcohol free” (0.0% ABV) rather than “non-alcoholic” (up to 0.5% ABV) if aiming for total abstinence during pregnancy.
