Non-alcoholic beer is not just regular beer with the alcohol drained out. Brewers use several different methods to get a beer down to 0.5% ABV or less, and the method matters – it is the single biggest reason some NA beers taste like real beer and others taste thin or sweet.
The two main approaches
1. Brewed to be low-alcohol from the start
Some brewers limit fermentation itself, using special low-attenuation yeast strains, a shortened fermentation time, or a very low original gravity wort so there is little sugar for the yeast to convert into alcohol in the first place. This keeps more of the original malt character intact, but it is harder to hit a full, hop-forward flavor this way, which is why many NA IPAs brewed this method lean on late hop additions to compensate.
2. Brewed full-strength, then dealcoholized
Most craft NA beer is actually brewed as a normal beer first and then has the alcohol removed afterward. The three common methods are:
- Vacuum distillation: the beer is heated under a vacuum, which lowers the boiling point of alcohol so it evaporates at a much lower temperature than in a normal still, preserving more flavor compounds than a standard boil would.
- Reverse osmosis: the beer is pushed through a fine membrane that separates out alcohol and water, which are then partially recombined with the remaining beer concentrate.
- Heat/thermal evaporation: an older, cheaper method that boils off alcohol directly – effective, but it also cooks off more of the beer’s aroma and flavor, which is why it has fallen out of favor with craft NA brewers chasing better taste.
Vacuum distillation is the method most modern craft NA brewers (Athletic Brewing among them) rely on, since it does the best job of stripping out alcohol while keeping hop aroma and malt character.
Why NA beer used to taste worse than it does now
Removing alcohol also removes some of the body and mouthfeel that alcohol itself provides, since alcohol carries flavor compounds and adds a subtle warmth and weight. Older NA beers, brewed mostly with heat evaporation, lost even more of that character on top of the alcohol. Better yeast strains, dry-hopping after dealcoholization, and additions like maltodextrin or specialty malts to rebuild body are the main reasons today’s NA beers taste closer to their alcoholic counterparts than they did a decade ago.
Does non-alcoholic beer have zero alcohol?
Not always. In the US, a beer can be labeled “non-alcoholic” at up to 0.5% ABV, the same threshold used across most of Europe. A beer labeled “alcohol-free” in the UK must be 0.05% ABV or less, a stricter bar. True 0.0% ABV beer exists too – it just takes an extra filtration or distillation pass to get there, which is part of why it tends to cost more.
How Is Non-Alcoholic Beer Made FAQs
Is non-alcoholic beer brewed the same as regular beer?
Usually yes, at least at the start. Most craft NA beer is brewed as a full-strength beer first, then has the alcohol removed afterward, most commonly through vacuum distillation.
What is the healthiest way non-alcoholic beer is made?
Vacuum distillation is generally considered the best method for both flavor and consistency, since it removes alcohol at a lower temperature than boiling and preserves more of the beer’s original character.
Why does non-alcoholic beer sometimes taste watery?
Alcohol carries flavor and adds body, so removing it can leave a thinner mouthfeel if the brewer does not compensate with specialty malts, dextrins, or extra dry-hopping after dealcoholization.
