Apex Cultures Special Sour Beer Yeast 500g

Apex Cultures Special Sour Beer Yeast 500g is a unique yeast strain, known as Lachancea termotholerans, that has been specifically designed for the production of sour-like beers. This yeast strain is naturally occurring and was originally isolated from premium grapes in Burgundy. It is known for its ability to produce a high concentration of lactic acid, which is the key ingredient that gives sour beers their distinctive taste.

The Special Sour Beer Yeast carries the lactate dehydrogenase gene along with the alcohol dehydrogenase gene. This combination allows it to ferment and sour your beer simultaneously, a process known as "primary souring". This technique offers you a way to bypass the use of lactic acid bacteria and kettle souring, saving you both time and money while still achieving the desired complex flavor profile.

With the Special Sour Beer Yeast, you can consistently produce a "crispy" beer with a more reproducible souring process. It is compatible with any conventional yeast and common fermentation procedures, making it a versatile choice for any sour-style beer production.

Here are the brewing properties of the Apex Cultures Special Sour Beer Yeast 500g:

- Fermentation Temperature: It operates best at a temperature range of 61-75°F.
- Apparent Attenuation: It has an apparent attenuation of 30%.
- Flocculation & Sedimentation: It exhibits medium flocculation and sedimentation.
- Dosage Recommendation: For optimal results, use 100-150g/hl at a temperature of 61-75°F.

While primarily used in beer making, the Special Sour Beer Yeast can also be used in the production of other fermented beverages that require a souring process. This makes it a versatile addition to your brewing supplies.
