Why is Non-Alcoholic Beer 0.5%?

We’ve all come across non-alcoholic beer on the shelves or during a night out, with its promise of the beer experience minus the alcohol content. But what strikes many is a surprising little detail on the label: 0.5% alcohol.

If it’s supposed to be non-alcoholic beer, why isn’t it completely free of alcohol?

The straightforward answer is that it’s due to the natural fermentation process and the regulatory definition of non-alcoholic drinks.

But, of course, there’s more to it. Let’s dive into the details.

Why is Non-Alcoholic Beer 0.5%?

The primary reason non-alcoholic beer contains up to 0.5% alcohol is because of the brewing process. Beer is made by fermenting sugars, and this fermentation inherently produces alcohol.

While most of the alcohol is removed in non-alcoholic beer production, a trace amount often remains.

The Brewing Process

Beer is typically brewed by fermenting malted grains like barley. Yeast is introduced, and it consumes the sugars from these grains, producing alcohol and carbon dioxide.

For non-alcoholic beer, breweries employ methods such as vacuum distillation or reverse osmosis to remove the alcohol after fermentation.

However, completely eliminating every trace of alcohol can be challenging, resulting in the minimal 0.5% alcohol content we see in many non-alcoholic beers.

Regulatory Definitions

The labeling of drinks as “non-alcoholic” varies from country to country. In many places, a drink with an alcohol content of up to 0.5% can legally be called non-alcoholic.

The reason why 0.5% drinks can be classed as non-alcoholic is that 0.5% is an incredibly low alcohol percentage. In fact, it’s similar to the amount of alcohol that you’d find in a very ripe banana!

This tiny percentage is considered negligible and doesn’t lead to intoxication, which is why drinks produced through natural fermentation processes containing up to 0.5% alcohol can still be classified as non-alcoholic.


Why don’t they just remove all the alcohol?
While it’s technically possible, removing every last trace of alcohol can be costly and can sometimes alter the taste of the drink. Keeping it at 0.5% strikes a balance between taste and alcohol removal.

Can you get drunk on non-alcoholic beer?
No, the alcohol content is too low. You would need to consume an impractically large amount to feel any effects.

Is there alcohol in other “non-alcoholic” drinks?
Yes, other fermented drinks, like non-alcoholic wines or kombucha, may also contain trace amounts of alcohol due to the fermentation process.

Does non-alcoholic beer taste different because of the 0.5% alcohol?
While the taste may vary from regular beer, it’s not just because of the 0.5% alcohol. The process used to remove alcohol can also influence the flavor.

Are there any benefits to drinking non-alcoholic beer?
Yes, you can enjoy the taste and social aspect of beer without the intoxicating effects or the higher calorie content of regular beer.


Non-alcoholic beer’s trace of up to 0.5% alcohol arises from the brewing process and the rules about what can be labeled “non-alcoholic.”

When you opt for a non-alcoholic beer, you’re choosing a taste close to traditional beer, but with barely any alcohol.

Some non-alcoholic beers are 0.5%, rather than 0.0%, in order to retain an authentic beer flavor while still being classed as non-alcoholic and remaining too low in alcohol to possibly make you drunk.
