Yeastex® is a formulation of specific yeast nutrients to increase yeast viability and activity during fermentation, allowing the end attenuation to be reached in a shorter time, and promoting consistent fermentation profiles.
This formulation contains high levels of both inorganic and organic nitrogen and vitamins and is particularly useful for low FAN malts, high gravity brewing. It should be slurried in a few gallons of water and added to the kettle about 15 minutes before strike-out.
Recommended usage for 5 gallons of wort is 1 gram of Yeastex. Mix Yeastex with a small amount of water and add to the kettle with 15 minutes left in your boil.
