What was a Seasonal Strain is now a permanent strain due to a very positive overall response. This yeast can supposedly ferment up to 25% alcohol. We have not had the opportunity to test it anywhere near that type of alcohol. We welcome feedback from customers. Produces ester character that increases with increasing gravity. Malt character dominates at lower gravities. After using this yeast strain we found out that it can sometimes produce a Belgian Character and sometimes not. Try this yeast with your big Belgians as well as other unique hybrids and you will find yourself pleasantly surprised. We would not recommend it for creating classic true-to-style variations of Barleywines, Imperial Stouts, Strong Ales or any other high-gravity style where Belgian flavors would not be appropriate. This yeast might be a great fit for really big Dunkelweizens.

Also note that with any beer with a starting gravity over 1.060 you should consider using nutrients. A recommended nutrient schedule is to add Servomyces to the kettle at the end of the boil, and then follow that with a 6 grams per 5 gallons addition of Fermaid K half-way through the fermentation.

Attenuation: 80%
