How To Brew Non Alcoholic Beer

has gained popularity in recent years as an alternative for those who want to enjoy the taste of beer without the effects of . But have you ever wondered how non-alcoholic beer is brewed? In this article, we will delve into the process and discover the methods used to create this alcohol-free .

The brewing process for non-alcoholic beer is quite similar to that of regular beer. It begins with making a mash, which involves mixing malted grains (such as barley) with hot . This mixture is then allowed to sit for a period of time, which activates enzymes in the grains and converts the starches into sugars.

After the mash, the liquid is separated from the grains, creating what is known as wort. The wort is then boiled and are added to give the beer its characteristic bitterness and aroma. Hops also act as a natural preservative in beer.

At this point, the brewing process for non-alcoholic beer diverges from regular beer. Instead of being bottled or kegged, non-alcoholic beer needs to have its alcohol content reduced or removed. There are several methods commonly used to achieve this.

One common method is steam distillation. In this process, the beer is heated until the alcohol evaporates, leaving behind an alcohol-free liquid. Another method is reverse osmosis, where the beer is passed through a fine mesh to separate the alcohol from the other flavored components. The alcohol is then discarded, and the remaining liquid is collected to create non-alcoholic beer.

Water vapor or gas stripping is another technique used to remove alcohol from beer. In this process, the beer is heated, and the alcohol is stripped away using water vapor or gas. This method is effective in reducing the alcohol content to very low levels.

In addition to the brewing process, there have been recent advancements in creating non-alcoholic beer that retains the aroma of hops. Traditionally, aroma hops are added during the brewing process, but their flavor is lost when the alcohol is removed. However, researchers have discovered a way to turn baker's cells into micro-factories that release the aroma of hops. These yeast cells can be grown in fermenters and added to the non-alcoholic beer, allowing it to have the characteristic hop aroma without the alcohol content.

Non-alcoholic beer is brewed using a similar process to regular beer, but with the additional step of removing or reducing the alcohol content. This can be achieved through methods such as steam distillation, reverse osmosis, or water vapor/gas stripping. Recent advancements have also allowed for the retention of hop aroma in non-alcoholic beer. Whether you choose non-alcoholic beer for health reasons or personal preference, it's clear that there are now more options than ever for enjoying the taste of beer without the alcohol.

How Do They Brew Non-alcoholic Beer?

Non-alcoholic beer is brewed using various techniques to remove or minimize the alcohol content. The most commonly used method is dealcoholisation, which involves removing alcohol from regular beer to make it alcohol-free. This process typically employs one of three techniques: steam distillation, reverse osmosis, or water vapour/gas stripping.

1. Steam Distillation: In this method, the beer is heated, and the alcohol is separated from the liquid using steam. The beer is heated to the point where the alcohol evaporates, and the resulting vapor is condensed and collected. This condensation process separates the alcohol from the other components of the beer, resulting in a lower alcohol content or alcohol-free beer.

2. Reverse Osmosis: Reverse osmosis is another popular technique used in the production of non-alcoholic beer. In this process, the beer is passed through a membrane that selectively allows molecules smaller than alcohol to pass through while retaining larger molecules. This separation process helps to remove the alcohol from the beer, resulting in a lower alcohol or alcohol-free product. The separated alcohol can be further concentrated and reused or discarded.

3. Water Vapour/Gas Stripping: Water vapour or gas stripping involves the introduction of steam or gas into the beer, which helps to remove the alcohol content. The steam or gas carries the alcohol molecules away from the beer, and the alcohol is then condensed and collected. This method is similar to steam distillation but may vary in the specific process and equipment used.

It's worth noting that the degree of alcohol removal can vary depending on the desired final alcohol content of the non-alcoholic beer. Some non-alcoholic beers may still contain trace amounts of alcohol, usually around 0.5% ABV (alcohol by volume) or less. This minimal alcohol content is often considered safe for consumption and is similar to the alcohol content found in naturally fermented foods or beverages.

Non-alcoholic beer is brewed using various techniques, with dealcoholisation being the most common method. Through processes like steam distillation, reverse osmosis, or water vapour/gas stripping, alcohol is removed from regular beer, resulting in the production of alcohol-free or low-alcohol beer.

How Do They Make Non-alcoholic Beer Taste Like Beer?

To make non-alcoholic beer taste like beer, several techniques are employed to mimic the flavors and characteristics of traditional beer. Here's a detailed explanation of the process:

1. Fermentation: Non-alcoholic beer starts with the same basic ingredients as regular beer, including water, malted barley, hops, and yeast. The brewing process begins by mashing malted barley in hot water to extract sugars. These sugars are then fermented by yeast, converting them into alcohol and carbon dioxide. However, in non-alcoholic beer production, the fermentation process is intentionally halted before significant alcohol production occurs.

2. Dealcoholization: Once the desired flavors and characteristics have developed during fermentation, the beer is subjected to a dealcoholization process. There are different techniques to remove the alcohol content, such as vacuum distillation, reverse osmosis, or evaporation. These methods aim to separate the alcohol from the rest of the beer while retaining its flavor compounds.

3. Flavor adjustment: After dealcoholization, the beer may undergo flavor adjustment to enhance the taste and aroma. This involves adding various ingredients, such as extracts, hop extracts, and other flavorings, to ensure the beer retains its characteristic flavors. These additions help compensate for any loss of flavor during the dealcoholization process.

4. Carbonation: Non-alcoholic beer is carbonated to provide the familiar effervescence found in traditional beer. Carbonation can be achieved through the injection of carbon dioxide or through natural carbonation during fermentation.

5. Quality control: Non-alcoholic beer undergoes rigorous quality control measures to ensure it meets the desired taste profile. This includes sensory evaluations, chemical analysis, and comparison with regular beer to ensure consistency and similarity in flavor.

By carefully managing the fermentation process, removing alcohol, adjusting flavors, and carbonating the beer, brewers can create a non-alcoholic beer that closely resembles the taste of regular beer. However, it's important to note that the absence of alcohol may lead to slight differences in mouthfeel and overall sensory experience compared to traditional beer.


Non-alcoholic beer is produced using the same brewing process as regular beer, but with an additional step of removing or reducing the alcohol content. This is typically done through processes such as steam distillation, reverse osmosis, or water vapour or gas stripping. The goal is to preserve the flavor and aroma of the beer while eliminating or reducing the alcohol content. Additionally, researchers have recently developed a method to enhance the aroma of non-alcoholic beer by using yeast cells as micro-factories to release the aroma of hops. These advancements in the production of non-alcoholic beer have allowed for a wider range of options for individuals who prefer or require alcohol-free beverages.
