Experimental Sourdough Starter: The Beer and Wine Method

Sourdough bread is prized for its tangy flavor, chewy texture, and crisp crust. While water and flour form the basis of most sourdough starters, adventurous bakers often experiment with other liquids to impart unique flavors and textures to their bread. Among these, alcohol – particularly beer and wine – has sparked interest. So, can you use beer or wine in your sourdough starter? Let’s delve into this.

Incorporating beer and wine into sourdough starter can offer unique flavors but may impact yeast activity due to their acidity and alcohol. Consistent use can unbalance the starter. For best results and long-term health, occasionally use them and primarily feed the starter with flour and water.

Considerations in using Beer and Wine in Sourdough Starters

1. Beer in Sourdough Starter

Beer is essentially liquid bread. It’s made from water, grains (like barley or wheat), and yeast, ingredients familiar to bread bakers.

Using beer can introduce new flavors, often deeper and more complex, influenced by the beer’s particular variety. Since beer undergoes fermentation, it contains active yeast that can potentially aid in jumpstarting a starter.

When alcohol concentrations are too high, they can create an inhospitable environment, suppressing these vigor of beneficial yeast and bacteria. As a precaution, many bakers opt for low-alcohol beers to maintain the vitality of their sourdough starters. If one chooses to use a beer with higher alcohol content, diluting it with water can help mitigate the inhibitory effects of the alcohol, ensuring a robust fermentation process.

2. Wine in Sourdough Starter

Wine, with its acidity and varied flavor profiles, can be an exciting addition to a sourdough starter.

Red or white wines can bring fruity, oaky, or tannic notes to your bread, offering a unique taste. The natural acidity in wine can help maintain the desired acidic environment in your starter, promoting the growth of beneficial microbes.

When considering the use of wine in sourdough starters, its alcohol content plays a crucial role. Just as with beer, higher alcohol levels in wine can hinder the activity of the beneficial yeast and bacteria essential for the fermentation process. Therefore, using wine with high alcohol concentrations might necessitate dilution with water to maintain a healthy and active starter.

Moreover, the sugar content in wine varies widely, with some wines being distinctly sweeter than others. The presence of these sugars can influence the fermentation dynamics of the sourdough starter. Specifically, heightened sugar levels can accelerate fermentation, leading to a more rapid rise and potentially altering the flavor profile of the bread. Bakers need to be mindful of this variable when incorporating different wines into their sourdough mixtures.

Practical Tips

1. Start Small

If you’re trying beer or wine for the first time in your starter, consider doing a small test batch. This way, you can gauge the results without risking your main starter.

2. Dilution

To ensure the alcohol doesn’t impede microbial activity, consider using a 50-50 mix of water and beer or wine.

3. Observe

Keep an eye on your starter. If it seems less active, the alcohol might be too inhibitive, and you may need to adjust the mixture or revert to water.


Using beer or wine in a sourdough starter can introduce new dimensions of flavor and character to your bread. However, like all experiments, it requires a balance of creativity and observation. Always remember to maintain the health and balance of your starter, ensuring its longevity and efficacy in producing delightful sourdough loaves.
