Why Do My Sourdough Starter Smells Like Alcohol? Here's What to Do

If you're a sourdough bread enthusiast, you know that a sourdough starter is a living, fermented mixture of flour and water that is used to leaven bread.

While it's normal for a sourdough starter to produce a small amount of alcohol as a byproduct of the fermentation process, a strong alcohol smell can be a cause for concern. In this article, we'll explore the science behind alcohol production in a sourdough starter, potential causes of a strong alcohol smell, and solutions for fixing the issue.

The science behind alcohol production in a sourdough starter

Alcohol is a byproduct of the fermentation process that occurs in a sourdough starter. When yeast and bacteria in the starter consume sugars and other nutrients, they release carbon dioxide, ethanol, and other compounds.

While a small amount of alcohol is normal in a sourdough starter, a strong alcohol smell could indicate an issue.

Potential causes of a strong alcohol smell in a sourdough starter

There are several potential causes of a strong alcohol smell in a sourdough starter. One common cause is overfeeding or underfeeding the starter. If you're feeding your starter too much or too little, the balance of yeast and bacteria could be thrown off, leading to an excess of alcohol production.

Other potential causes of a strong alcohol smell include using too much or too little water, using certain types of flour or water, or storing the starter in a warm place. These factors can all affect the balance of the starter and lead to an excess of alcohol production.

Sourdough Starter Smells Like Alcohol: Solutions

Here are some things you can try if your sourdough starter has an alcohol smell:

1. Adjust the feeding schedule

If you're overfeeding or underfeeding your starter, try adjusting the amount of flour and water you add to achieve a healthy balance.

2. Use a different type of flour or water

Experiment with different flours or waters to see if they have an impact on the alcohol smell. Some people find that using whole grain flours or filtered water can help to reduce the alcohol smell in their starter.

3. Store the starter in a cooler place

If you're storing your starter in a warm place, try moving it to a cooler spot to see if it makes a difference. Yeasts and bacteria are more active at warmer temperatures, so storing the starter in a cooler place could help to reduce the amount of alcohol produced.

4. Follow a balanced feeding schedule

Maintaining a balanced feeding schedule is important for the health of your starter and can help to prevent issues like a strong alcohol smell. Aim to feed your starter at regular intervals and use equal amounts of flour and water to keep the starter healthy and active.

Conclusion

If your sourdough starter smells like alcohol, don't panic! There are several potential causes and solutions for this issue. By adjusting the feeding schedule, using a different type of flour or water, or storing the starter in a cooler place, you may be able to fix the problem and get your starter back on track. Remember to maintain a balanced and healthy starter to prevent issues like a strong alcohol smell in the future.
