Did you know that some foods contain alcohol? Or that even selected sodas and soft drinks carry a small percentage of it? Fermented foods are among the culprits, as are various fruit juices and condiments. But exactly how much alcohol are we taking about, and what can be done to reduce levels?
If you're curious about which everyday products are affected, or looking to lead a completely alcohol-free lifestyle, click through and digest this list of common foods and drinks you didn't know contain alcohol.
As a fermented food, yogurt contains alcohol. Likewise, alcohol is also present in kefir, a fermented milk drink similar to a thin yogurt or ayran (a cold beverage of Turkish origin). The average ABV is between 0.05-2%.
Generally speaking, dairy products that are fermented sit at the lower end of the ABV scale.
Most sodas, especially sugar-free varieties, contain small quantities of alcohol, up to 0.5% ABV in some cases. Better-known brands include Coca-Cola, Fanta, Sprite, and Dr. Pepper.
The percentage of ABV in soft drinks though is minimal and quite harmless. In fact, it's the high sugar content we should be more mindful of.
Yeast and other bacteria in baked goods can produce small amounts of alcohol during the fermenting process, anywhere between 1.18-1.28% ABV.
Some breads are known to have elevated percentages of ABV, burger rolls, for example, and rye bread. French-style sweet milk rolls have the highest ABV, approximately 1.30%.
Certain fruits and fruit juices contain higher than average trace elements of alcohol, specifically orange, apple, and grape, all of which contain between 0.04-0.5% ABV.
While fruit juices aren't exactly fermented, they can produce alcohol during the harvest process when undergoing heat treatment. Apple juice tends to have the lowest ABV, while orange juice hovers midway on the scale. Grape juice averages the most alcohol content.
Kombucha tea is often labeled as "non-alcoholic," but in fact can contain anywhere between 0.5-5% ABV. The reason for this is again because of the fermenting process.
Must is the name given to freshly pressed grape juice, containing the skins and stems of the grapes. Must is actually the first step in winemaking after harvest. The concoction, however, makes for a refreshing drink all on its own. But by its very nature, must can contain up to 5% ABV.
Balsamic vinegar and gourmet vinegars, namely champagne, sherry, and red and white wine vinegars, contain anywhere between 0.1-0.4% ABV.
Even if these desserts are baked, the heat only eliminates about 60% of the alcohol content. But there's no need for concern. The amount of vanilla extract used in these products is almost negligible, so there is no real harm indulging in them now and again, at least not as far as alcohol is concerned.
It is surprising how often alcohol shows up in a standard grocery haul. Most of these aren't going to give you a "buzz," but for those avoiding it for religious, health, or personal reasons, the percentages can be high enough to notice.
Here are some common foods that naturally contain or use alcohol during processing:
1. Ripe Bananas
As fruit ripens, the sugars ferment. A very ripe banana (with brown spots) can contain up to 0.5g of alcohol. While that sounds tiny, eating five very ripe bananas is chemically similar to drinking a light beer.
2. Burger Buns and Sliced Bread
Because bread relies on yeast fermentation to rise, alcohol is a natural byproduct. While most of it evaporates during baking, many commercial burger buns and "long-life" white breads retain up to 1.2% ABV (Alcohol By Volume).
Note: This is why a freshly opened bag of cheap sandwich bread sometimes smells slightly like beer.
3. Fruit Juices
Even if they aren't labeled "cider," many juices undergo spontaneous fermentation on the shelf.
Orange Juice: Can contain up to 0.7g/L.
Apple Juice: Often tests around 0.2g/L.
4. Yogurt and Kefir
Because these are fermented dairy products, they contain trace amounts of ethanol. Kefir, specifically, is known for having a slightly higher alcohol content (between 0.5% and 1.0%) due to the specific yeast and bacteria "grains" used to culture it.
5. Vanilla Extract
This is the "stealth" heavyweight. Pure vanilla extract is required by law in many regions to contain at least 35% alcohol to keep the vanillin from the beans in solution.
While most of it burns off in a baked cake, it remains fully present in "no-bake" desserts like puddings or whipped cream.
6. Soy Sauce
Traditional soy sauce is made by fermenting soybeans and wheat. This process results in a natural alcohol content of about 1.5% to 2%. It helps act as a preservative and enhances the aroma of the sauce.
Summary Table
| Food Item | Typical ABV / Amount | Primary Reason |
| Kefir | 0.5% – 1.0% | Yeast fermentation |
| Burger Buns | Up to 1.2% | Yeast byproduct |
| Ripe Banana | ~0.4% | Natural ripening |
| Soy Sauce | 1.5% – 2.0% | Fermentation/Preservation |
| Vanilla Extract | 35% | Solvent for flavor |
