will non alcoholic beer show up on a breathalyzer
It can, briefly. Non-alcoholic beer in the US may contain up to just under 0.5% alcohol by volume, and alcohol left in the mouth can cause a small false reading right after drinking. A study of drinks with trace ethanol found those readings were gone by 15 minutes. We found no official study that tested non-alcoholic beer itself.

The federal Alcohol and Tobacco Tax and Trade Bureau (TTB) separates malt drinks at 0.0% alcohol by volume (ABV) from those with “more than 0.0 and less than 0.5%”. Only the 0.0% group may be labeled “alcohol free”. A beer sold as “non-alcoholic” can therefore contain a small amount.
What research shows
A 2009 study in the Journal of Analytical Toxicology tested 27 energy drinks. Gas chromatography found low ethanol (5 to 230 mg/dL) in 24 of them. After volunteers drank them, 11 of the 27 drinks produced positive readings on a portable breath tester when samples were taken within a minute of finishing. Every test taken at least 15 minutes after drinking read zero. The authors concluded that a 15-minute observation period prevents these small false positives.
This study did not test non-alcoholic beer. It shows how trace alcohol in a drink can cause a short-lived reading, not what a specific beer will do.
What this means for you
- A reading straight after a sip is more likely than one 15 minutes later.
- Check the label: 0.0% means no alcohol, “less than 0.5%” means a trace is possible.
- If you have a legal, work or court-ordered testing rule, ask the testing program or a lawyer before you drink any beer, including non-alcoholic.

People also ask
Can non-alcoholic beer make you fail a breath test?
Possibly right after drinking, from trace alcohol in the mouth. A study of trace-ethanol drinks found readings were zero after 15 minutes.
Is non-alcoholic beer 0.0% alcohol?
Not always. TTB allows "non-alcoholic" for under 0.5% ABV; only 0.0% products may say "alcohol free".
How long should I wait before a breath test?
The study found that a 15-minute observation period removed the false readings. Follow the rules of whoever is testing you.
