Whether you’re a consumer curious about the drink or someone interested in brewing your own, knowing the alcohol content and how it’s created is essential to appreciating this popular beverage.
How Alcoholic Ginger Beer Is Made
The production of alcoholic ginger beer is rooted in the same principles that apply to other fermented alcoholic drinks. At the heart of alcoholic ginger beer is yeast, a microorganism that plays a critical role in fermentation. The basic fermentation process involves converting sugars into alcohol and carbon dioxide. In the case of alcoholic ginger beer, the primary sugars used in the fermentation process are either derived from ginger itself, added sugars, or malted barley, depending on the recipe used by the brewer.
The Key Ingredients: Ginger, Sugar, and Yeast
To start, ginger beer (both alcoholic and non-alcoholic versions) typically uses fresh ginger or ginger extract to provide its distinctive spicy, aromatic flavor. Sugar, usually in the form of cane sugar or high-fructose corn syrup, is added to the mix because it acts as the food source for yeast. The sugar is vital because yeast cannot ferment without it. The yeast then feeds on the sugars, producing alcohol as a byproduct, alongside carbon dioxide. This is the basic chemical process known as fermentation.
The type of yeast used can vary depending on the desired characteristics of the final product. Brewers may use different strains of yeast to control the flavor profile, mouthfeel, and alcohol content. Common yeast strains used for brewing alcoholic ginger beer include Saccharomyces cerevisiae, a strain often used in beer brewing, as well as other specialized yeasts that produce varying levels of alcohol and flavors. The type of yeast used can impact how the drink tastes and how high its alcohol content becomes. Yeast also contributes to the natural carbonation of the beverage, making it fizzy without the need for added carbonation.
Fermentation and Alcohol Production
Once the ingredients are combined—ginger, sugar, water, and yeast—the mixture is left to ferment. During fermentation, the yeast breaks down the sugars into alcohol (ethanol) and carbon dioxide. The carbon dioxide is what gives the ginger beer its effervescence, while the ethanol provides the alcoholic content. The fermentation process typically lasts anywhere from 24 hours to several days, depending on the desired alcohol concentration and flavor.
The alcohol content of alcoholic ginger beer can vary based on several factors, including the fermentation time, the amount of sugar used, and the specific yeast strain. On average, alcoholic ginger beers typically have an alcohol by volume (ABV) ranging from 4% to 6%, although some versions may go higher or lower depending on the style. Brewers can adjust the fermentation process to create different levels of alcohol, which can influence the drink’s final taste.
Types of Alcohol Found in Alcoholic Ginger Beer
In alcoholic ginger beer, the primary alcohol produced is ethanol (C2H5OH), the same alcohol found in all alcoholic beverages. However, the alcohol content of ginger beer isn’t the only factor that determines its appeal. The way the yeast ferments the sugars and the additional ingredients used in the brewing process also influence the drink’s final alcohol characteristics.
Ethanol: The Main Alcohol
Ethanol is the alcohol produced during the fermentation of sugars by yeast, and it is the type of alcohol found in alcoholic ginger beer. Ethanol is the intoxicating ingredient that gives the drink its alcohol content, and it is the same compound found in beer, wine, and spirits. The level of ethanol in alcoholic ginger beer typically falls in the range of 4% to 6% ABV, though variations exist based on the brewer’s process.
The amount of ethanol depends on several factors, including how much sugar is in the initial mixture, the length of the fermentation process, and the yeast strain used. In some recipes, higher sugar content can result in a higher alcohol concentration because there is more sugar for the yeast to convert into ethanol. Similarly, a longer fermentation process allows yeast more time to ferment sugars, which can also increase the alcohol content. However, brewers often stop fermentation at a certain point to balance the alcohol concentration with the desired flavor profile and sweetness.
Alcoholic Ginger Beer vs. Non-Alcoholic Ginger Beer
It’s important to distinguish alcoholic ginger beer from its non-alcoholic counterpart, which is sometimes referred to simply as “ginger beer” and is a common mixer for cocktails. Non-alcoholic ginger beer is made with a similar process but does not undergo fermentation. Instead of yeast fermentation, non-alcoholic ginger beer is usually carbonated artificially or by natural fermentation without alcohol production.
Non-alcoholic ginger beer still contains ginger and sugars, but since it doesn’t ferment, it lacks the ethanol that is characteristic of alcoholic versions. The flavor of non-alcoholic ginger beer can still be quite strong, with ginger providing the spice and sweetness, but it will not have the warming, intoxicating effect of the alcoholic variety. For this reason, non-alcoholic ginger beer can be enjoyed by anyone, regardless of age, while alcoholic ginger beer is regulated in the same way as other alcoholic beverages.

Factors Affecting Alcohol Content in Alcoholic Ginger Beer
Several factors influence the alcohol content in alcoholic ginger beer. These factors include the sugar concentration, yeast strain, fermentation time, and the brewing environment. Understanding these elements helps explain why alcoholic ginger beers vary in strength and flavor.
Sugar Concentration and Its Impact on Alcohol Content
One of the primary factors influencing the alcohol content in alcoholic ginger beer is the sugar concentration in the initial mix. Sugar is the key ingredient that yeast feeds on to produce alcohol, so the higher the sugar content, the greater the potential for alcohol production. Brewers often experiment with different sugar sources, including cane sugar, honey, or even fruit juices, to achieve different levels of sweetness and alcohol.
If a brewer adds more sugar, the yeast will have more food to consume, which leads to more fermentation and, consequently, a higher alcohol content. On the other hand, if the sugar is more diluted, the yeast will produce less alcohol. This balance between sugar and yeast is crucial in achieving the desired taste and alcohol level. Some brewers intentionally stop the fermentation process before all the sugar is converted into alcohol to maintain a sweeter taste.
Yeast Strains and Alcohol Production
The strain of yeast used also plays a critical role in determining the alcohol content. Different yeast strains ferment sugars at different rates and can produce varying amounts of alcohol. Some strains are better suited for producing high alcohol content, while others are more suited for low-alcohol or sweeter beverages.
For example, ale yeast strains are commonly used in the production of alcoholic ginger beer because they are known to create relatively low to moderate alcohol levels while contributing to fruity and spicy flavors. Certain strains of wild yeast, on the other hand, may produce unique flavors but can sometimes result in inconsistent fermentation. The specific yeast chosen will influence the drink’s alcohol content, flavor, and mouthfeel.
Fermentation Time and Temperature Control
The duration of fermentation and the temperature at which it occurs can also impact the alcohol content of ginger beer. Yeast thrives at specific temperatures, typically between 65°F and 75°F (18°C to 24°C), and the fermentation rate speeds up at higher temperatures. Brewers can control the length of fermentation to manipulate the alcohol content, stopping the fermentation at a point where the alcohol level meets their desired specifications.
If a brew is fermented for a shorter period, it may result in a lower alcohol content, as the yeast will not have had as much time to consume the sugars. Conversely, longer fermentation can lead to higher alcohol levels as the yeast consumes all available sugars. This balance is carefully managed to ensure that the final product has the right combination of flavor, carbonation, and alcohol strength.
The Role of Carbonation in Alcoholic Ginger Beer
While carbonation does not directly affect the alcohol content, it plays a significant role in the overall experience of drinking alcoholic ginger beer. The natural carbonation produced during fermentation adds to the drink’s refreshing effervescence. The carbon dioxide gas released by the yeast is trapped in the liquid, creating the fizzy sensation associated with ginger beer.
In some cases, carbonation may be artificially added after fermentation, especially if the natural carbonation is insufficient or if the brewer wishes to enhance the fizziness of the drink. The level of carbonation, however, is typically lower in alcoholic ginger beer compared to sodas or sparkling wines, giving it a more subtle and smooth effervescence that complements the spicy ginger flavor.
Conclusion
Alcoholic ginger beer is a delicious and unique alcoholic beverage that offers a flavorful alternative to traditional beer and other spirits. Its alcohol content primarily comes from ethanol, produced through the fermentation of sugars by yeast. The amount of alcohol in the beverage can vary depending on factors such as sugar content, yeast strain, fermentation time, and brewing methods.
Understanding how alcohol is produced in ginger beer, as well as the various factors that affect its alcohol content, can enhance your appreciation of this drink. Whether you’re brewing your own batch at home or enjoying a commercial brand, knowing the science behind alcoholic ginger beer allows you to make informed choices about your consumption.
