Yeast, a vital microorganism in the fungi family, plays a pivotal role in the production of spirits. Choosing the right yeast for distilling alcohol is crucial for the fermentation process, converting sugars into ethanol, carbon dioxide, and flavour-active metabolites.

There are various types of yeast, including distiller’s yeast, brewer’s yeast, and baker’s yeast, each having unique properties.

Understanding Distilling Yeast for a new distiller

Distilling yeast, specifically saccharomyces cerevisiae, is adept at metabolising sugar into alcohol. Its impact on the flavour of the final spirit is significant, making the choice of the right distilling yeast strain crucial.


Factors to Consider When Choosing the Best Yeast for Distilling Alcohol

Attenuation: Efficiency in converting sugars to alcohol percentage.

Flocculation: Yeast’s ability to clump together at fermentation’s end.

Temperature Range: Optimal range for fermentation.

Alcohol Tolerance: The maximum alcohol percentage yeast can produce, like baker’s yeast, which has a tolerance of 10 to 12%.

Flavour and Aroma: Yeast produces volatile components like esters, influencing aroma and flavour.

Fermentation Rate: Time required for yeast to convert sugar to alcohol, typically 3 to 7 days.


Popular Distilling Yeast Strains

Selecting a readily available yeast strain is advisable. Some popular options include:

Red Star (DADY yeast)

Ale yeast

Alcotec yeast range

Baker’s Yeast – This is what we use

Distilamax (replacing activated dry yeast)

Turbo yeast (prepacked with nutrients and additives)

Champagne yeast

Lallemand yeast

What is the Right Yeast for Distilling Alcohol

For flavours and aromas, mixing different yeast strains at various fermentation stages is an option, though it’s not recommended for beginners. Serious distillers often prefer professional-grade yeasts like Fermentis/Lesaffre or Lallemand strains. These depend on your requirements.


Diving Deeper into Yeast Strains

Turbo Yeast: This strain, prepacked with nutrients and additives, can tolerate alcohol levels up to 20%. However, troubleshooting issues during fermentation can be challenging due to its complex composition.

Champagne Yeast: Known for its suitability in turning base wine to Champagne, though it is more expensive.

Distilamax Yeast: Ideal for continuous ethanol fermentations, this active dry yeast requires added nutrients, allowing for experimentation with flavour and aroma. It operates well up to 34 Celsius and within a pH range of 3.5 to 6.

Baker’s Yeast: Produces alcohol from 8 to 13% ABV. Like Distilamax, it requires added nutrients and offers a pleasant smell during fermentation. It works best at temperatures between 28 to 32 Celsius and a pH range of 4.8 to 5.5.

Baker’s Dried active yeast
– alcohol content (10% to 13%)
25 to 30°C (77 to 86°F)
Distiller’s yeast
– alcohol content (10% to 13%)
20 to 34°C (68 to 95°F)
Turbo Yeast variants
– alcohol content (15% to 20%)
can start as high as 40°C (104°F), read the instructions as they are different

Note on Yeast Preparation

Before adding yeast to the fermenter, ensure the pH is between 4.8 to 5.5 and the mixture is well-aerated. This preparation is essential for optimal yeast performance.

From turbo yeast to distillers yeast, it’s your choice 

The choice of yeast for distilling alcohol is a critical factor in the spirit-making process. Each yeast strain offers unique characteristics that can significantly impact the flavour, aroma, and quality of the final product.

Understanding these properties and choosing the right yeast for your distilling, leads to high-quality spirits that stand out in taste and character.

Our choice is baker’s bread yeast for distilling alcohol as we can control the nutrients that go into the batch plus we can control ferment if any issues arise. We create a sugar wash to use a reflux still to get a neutral spirit. Once the spirit is distilled we add essences such as whiskey, rum, or vodka.
