Can Bread Yeast be Used to Make Wine?

Bread , also known as baking yeast, is commonly used in the kitchen for baking bread and other pastries. It is a type of yeast that is readily available and inexpensive. However, when it comes to winemaking, bread yeast may not be the best choice.

One of the main differences between bread yeast and yeast is their tolerance towards . Bread yeast can produce alcohol up to 6-8% v/v, which is suitable for low alcoholic strength drinks like or . However, winemakers often aim for higher alcohol content in their wines, and bread yeast may not be able to survive in such high alcohol environments.

Wine yeast, specifically Saccharomyces Cerevisiae, is the most commonly used yeast for winemaking. It is bred to tolerate higher levels of alcohol and can ferment the sugars in grape to produce a higher alcohol content. This yeast strain is specifically selected for its ability to bring the wine to complete fermentation.

Using bread yeast to make wine may result in incomplete fermentation and a lower alcohol content than desired. Additionally, the flavors and aromas produced by bread yeast may not be suitable for wine production. Wine yeast is specifically bred to enhance the flavors and characteristics of wine, while bread yeast is not.

While it is technically possible to use bread yeast to make wine, it is not recommended by experts in the field. The quality of the resulting wine may be compromised, and it may not meet the standards expected of a well-made wine.

Bread yeast and wine yeast are not the same. Bread yeast is suitable for baking bread and other pastries, while wine yeast is specifically bred for winemaking. If you are looking to make wine at home, it is best to use wine yeast to ensure a successful fermentation and a high-quality end product.

What Happens If You Use Bread Yeast To Make Alcohol?

If you use bread yeast to make alcohol, there are a few things that will happen. Bread yeast is not specifically designed for making alcohol, so it has a lower tolerance towards alcohol compared to specialized yeast strains used in winemaking or . Here is a breakdown of what you can expect:

1. Lower alcohol production: Bread yeast can produce alcohol up to a certain limit, typically around 6-8% v/v (volume per volume). This means that if you are aiming for higher alcohol content in your alcoholic , bread yeast may not be able to survive and continue fermenting. Specialized yeast strains used in winemaking and brewing can tolerate much higher alcohol concentrations, allowing for the production of beverages with higher alcohol content.

2. Slower fermentation: Bread yeast may ferment at a slower rate compared to specialized yeast strains. This can prolong the fermentation process, requiring more time for the yeast to convert the sugars into alcohol. Patience is necessary when using bread yeast, as the fermentation process may take longer.

3. Different flavors: The use of bread yeast can result in different flavors compared to using specialized yeast strains. Bread yeast can contribute to a more bready or yeasty flavor profile in the final product. This may be desirable in some cases, such as when making certain types of beer or bread-based alcoholic beverages.

4. Risk of off-flavors or stuck fermentation: Bread yeast is not specifically selected for alcohol production, so there is a higher risk of off-flavors or stuck fermentation. Stuck fermentation occurs when the yeast stops fermenting before all the sugars have been converted into alcohol. This can result in a sweet or sugary taste in the final product. To minimize these risks, it is important to closely monitor the fermentation process and provide optimal conditions for the yeast.

Using bread yeast to make alcohol is possible, but it has limitations in terms of alcohol tolerance and flavor profile. If you are producing low alcoholic strength drinks like beer or cider, bread yeast can be suitable. However, for higher alcohol content beverages like wine or , it is recommended to use specialized yeast strains that are better suited for alcohol production.

Is Wine Yeast The Same As Bread Yeast?

Wine yeast is not the same as bread yeast. They are two different types of yeast with distinct characteristics and purposes. Here are some key differences between wine yeast and bread yeast:

1. Fermentation: Wine yeast is specifically selected for its ability to ferment grape juice into wine, while bread yeast is chosen for its leavening properties in dough.

2. Alcohol tolerance: Wine yeast is bred to withstand higher alcohol levels, as it needs to ferment the sugars in grape juice into wine, which typically has a higher alcohol content. Bread yeast, on the other hand, is not designed to tolerate high alcohol levels.

3. Flavor profile: Wine yeast can contribute to the flavor profile of the wine, producing different aromas and flavors during fermentation. Bread yeast, on the contrary, is not intended to add distinct flavors to the bread dough.

4. Nutrient requirements: Wine yeast may have different nutrient requirements compared to bread yeast due to the specific needs of the fermentation process. These nutrients can affect the growth, metabolism, and overall performance of the yeast during fermentation.

5. Availability: Wine yeast and bread yeast are usually sold separately, catering to their specific applications. Wine yeast can be found in specialized stores or online, while bread yeast is widely available in grocery stores.

Wine yeast and bread yeast are different in terms of their fermentation capabilities, alcohol tolerance, flavor contribution, nutrient requirements, and availability. Therefore, it is not advisable to use bread yeast as a substitute for wine yeast when making wine.


Bread yeast is a versatile and commonly used yeast that is suitable for producing low alcoholic beverages such as beer, cider, and other low alcoholic strength drinks. It has a tolerance towards alcohol of up to 6-8% v/v, making it ideal for homebrewing enthusiasts. However, when it comes to winemaking, bread yeast falls short as it cannot survive the high alcohol content desired by winemakers. Wine yeast, such as Saccharomyces Cerevisiae, is specifically bred to obtain higher alcohol levels and is the preferred choice for winemaking. Therefore, it is not recommended to use bread yeast for making wine. Understanding the differences between bread yeast and wine yeast is crucial in ensuring the desired outcome when brewing different types of alcoholic beverages.
