SafAle K-97 is a versatile German ale yeast popular among homebrewers for producing a variety of beer styles. It’s particularly well-suited for brewing German ales, Kölsch, Belgian witbiers, and session beers. This yeast typically produces a subtle fermentation character with a balanced, floral, and slightly fruity profile when fermented at lower temperatures.
However, at higher fermentation temperatures (around 20-22°C), it can generate more pronounced esters, including banana and bubblegum notes.
K-97 is known for its ability to create clear beers with a large, firm head and works well with heavily hopped recipes. Its versatility and ability to produce clean, crisp beers make it an excellent choice for homebrewers looking to craft German-style ales or experiment with various light-bodied, refreshing beer styles.

For ideal results, it’s important to take into account factors such as original gravity, fermentation temperature, and yeast viability when determining the exact dosage.

Directions for Use
Direct pitching is the preferred method for using Fermentis Safale K-97 Yeast. However, rehydration can be performed if desired. Follow the instructions below for either method:
Direct Pitching:
- Sprinkle the yeast evenly on the wort surface at fermentation temperature
- Guarantee complete coverage to avoid clumping
- Gently stir the wort after 30 minutes to fully incorporate the yeast
Rehydration:
- Mix the yeast with 10 times its weight of sterile water or wort (25-29°C)
- Allow the yeast to rest for 15-30 minutes
- Gently stir for 30 minutes
- Pitch the rehydrated yeast into the fermentation vessel
For both methods, use 50 to 80 g of yeast per hectolitre of wort. Maintain fermentation temperature between 18-26°C for ideal results. This yeast is known for producing clean, balanced ales and is particularly suited for American-style beers. It forms a firm foam head and remains suspended during fermentation, guaranteeing consistent performance.
K-97 Yeast Alternatives:
CellarScience – GERMAN Weihenstephan Lager Yeast
This yeast serves as an excellent alternative to K-97 due to its ability to ferment cleanly and crisply, resulting in beers with a flavor profile akin to Kölsch. Despite being a lager yeast, it performs well at ale temperatures, offering versatility for brewers who seek a clean fermentation character.
Fermentis SafLager S-23 Yeast
SafLager S-23 is a great substitute for K-97, especially for those fermenting at warmer temperatures similar to ale yeasts. It produces a clean flavor profile with subtle fruitiness, closely aligning with K-97 characteristics. The yeast yields beers with a crisp finish, ideal for Kölsch-style ales.
Lallemand Munich Classic Wheat Beer Yeast
Primarily used in wheat beers, this yeast can be a good alternative to K-97 for those looking to introduce subtle fruity esters into their brews. It ferments cleanly at cooler temperatures, achieving a similar profile to K-97 while adding a hint of complexity to the final product.
Mangrove Jack’s M84 Bohemian Lager Yeast
M84 is another solid option when K-97 is unavailable. It ferments well at higher temperatures, blending the attributes of lager and ale yeasts. This yeast produces clean, crisp beers with a delicate fruity character, making it suitable for brewing Kölsch-style beers.
These alternatives can help you craft beers with similar characteristics to those made with K-97, though each yeast may introduce its own subtle nuances. Consider factors such as fermentation temperature, flocculation, and attenuation when choosing the best substitute yeast for your brew.
