Ginger beer has a long history as a fiery, refreshing beverage, but its name leads to constant confusion about whether it belongs in the soda aisle or the alcohol section. Understanding how ginger beer is made is key to knowing what you are buying and whether it is suitable for everyone.
Quick answer: Modern commercial ginger beer is typically a non-alcoholic, carbonated soft drink brewed with ginger, sugar, and water, containing less than 0.5% ABV (alcohol by volume). However, traditional home-brewed ginger beer and specific "hard" ginger beers are fermented using yeast and can contain anywhere from 1% to 6% ABV.
Dietary note: Standard ginger beers can be high in added sugars, so individuals managing blood sugar or avoiding alcohol should check labels carefully to distinguish between soft drinks, traditional ferments, and alcoholic versions.
This guide covers the history of ginger beer, how fermentation affects alcohol levels, how it compares to ginger ale, and what to look for on commercial labels.
Ginger beer originated in Yorkshire, England, in the mid-eighteenth century. It was created as a fermented beverage using ginger, water, sugar, and a starter culture known as the "ginger beer plant" (GBP). The GBP is not actually a plant, but rather a symbiotic culture of bacteria (primarily Brevibacterium vermiforme) and yeast (Saccharomyces florentinus) that forms gelatinous granules.
The mixture was left to ferment in earthenware jars for several days. This process created a fizzy, spicy, and naturally carbonated beverage with an alcohol content that frequently exceeded 11% ABV. The drink became popular across the UK and was exported worldwide. In the early twentieth century, temperance movements and changes in excise taxes led commercial manufacturers to reduce the fermentation times, bringing the alcohol level down to negligible amounts.
The production method dictates the final alcohol content of the beverage. There are three main ways ginger beer is manufactured today:
1. Carbonated Ginger Soda (Most Common Commercial Method): Most ginger beers found in supermarkets today are not fermented. Instead, they are made by combining carbonated water with sugar syrup, citric acid, and natural ginger extracts or juice. These beverages contain 0.0% to 0.5% ABV and are classified as non-alcoholic soft drinks. They are popular soda alternatives for people trying to quit standard colas.
2. Traditional Wild Fermentation (Ginger Bug Method): Traditional ginger beer is made by fermenting ginger, sugar, and water with a "ginger bug." A ginger bug is a wild fermentation starter made by mixing fresh grated ginger, sugar, and water, allowing the wild yeasts and lactic acid bacteria on the ginger skin to multiply. Just like other traditional fermented beverages such as Mexican Tepache, ginger beer relies on sugar to feed yeast. When added to a sweet ginger tea and bottled, the yeast consumes the sugar, producing carbon dioxide (natural fizz) and a small amount of alcohol (typically 0.5% to 2% ABV) over a few days. If you are preparing a ginger bug at home, compare it with our recipes for Mexican agua fresca or Caribbean sorrel.
3. Hard Ginger Beer (Brewed Alcoholic Beverage): Some producers intentionally brew ginger beer to standard alcoholic strengths using beer-making equipment, malted barley, and specific brewer's yeast strains. These drinks are marketed alongside craft beers and ciders, containing 4% to 6% ABV, and are strictly restricted to adults. Those who manage blood sugar, such as on a diabetic-friendly diet or a structured weight loss plan, must verify labels carefully.
Although they share a primary flavor ingredient, ginger beer and ginger ale are completely different beverages in texture, intensity, and manufacturing. The following table highlights the key differences:
| Feature | Ginger Beer | Ginger Ale |
|---|---|---|
| Production Method | Brewed or fermented (traditionally); or carbonated ginger syrup | Plain carbonated water mixed with ginger flavoring/syrup |
| Appearance | Cloudy, opaque, often with sediment at the bottom | Clear, translucent, golden or pale amber |
| Flavor Profile | Fiery, intensely spicy, robust, and gingery | Sweet, mild, clean, lightly carbonated |
| Ingredients | Real ginger root, sugar, yeast/starter, water | Carbonated water, corn syrup/sugar, ginger flavor, citric acid |
| Alcohol Content | 0.0% to 0.5% (commercial), up to 6% (hard/traditional) | 0% ABV (always alcohol-free) |
| Primary Use | Cocktail mixer (Mules), bold standalone beverage | Mild mixer, stomach settler, general soft drink |
Final takeaway: Most commercial ginger beers are non-alcoholic soft drinks, but traditional home-brewed versions and "hard" ginger beers contain alcohol.
Best choice: Non-alcoholic commercial ginger beer made with real ginger for Moscow Mules and mocktails.
Main caution: Read labels carefully to identify "hard" ginger beers, and check sugar content if managing blood sugar.
Next step: Try a refreshing non-alcoholic ginger beer mocktail with lime and mint.
Most commercial ginger beers found in the soda aisle are non-alcoholic (less than 0.5% ABV). However, traditional brewed ginger beers can contain 0.5% to 2% ABV, and "hard" ginger beers are specifically brewed to contain 4% to 6% ABV.
Ginger beer is traditionally fermented, cloudy, and has a strong, spicy, fiery ginger flavor. Ginger ale is a clear carbonated water sweetened and flavored with a mild ginger syrup, offering a sweet and gentle taste.
Yes. Since most commercial ginger beers are non-alcoholic soft drinks containing less than 0.5% ABV, they are safe for children. However, always verify that the bottle is not marked as "hard" or alcoholic.
Traditional ginger beer is fermented using a "ginger bug," which is a mixture of fresh grated ginger, sugar, and water that has fermented naturally with wild yeasts and bacteria. The bug is mixed with ginger tea and bottled to ferment further. If you are preparing a ginger bug at home, compare it with our recipes for Mexican agua fresca or Caribbean sorrel.
High-quality commercial ginger beers and all traditional home-brewed versions use real ginger root. Lower-cost commercial ginger ales and sodas often rely on artificial or natural ginger flavorings.
Most standard commercial ginger beers are naturally gluten-free because they are made from ginger, sugar, water, and yeast. However, some brewed hard ginger beers use barley or other grains, so individuals with coeliac disease should check labels carefully.
It is called ginger beer because it was historically brewed and fermented using yeast, water, and sugar in the 18th century, which produced an alcoholic beverage. The name stuck even after commercial recipes were modified into non-alcoholic soft drinks.
Yes, ginger beer containing real ginger can help settle an upset stomach because ginger contains gingerols, which have natural anti-nausea properties. However, ginger ale is often preferred because it is milder and less spicy. Ginger provides stomach comfort similar to carrot celery juice or small Citrus shots.
