Yeastex 61
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 inorganic nitrogen and is particularly useful for low FAN malts, high gravity brewing, wine, cider and malternative beverages. 35 pounds
Yeastex 82
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. 88 pounds
Nutramix LN
This is a blend of minerals and vitamins essential for yeast growth. It contains no Diammonium phosphate making it productive for alternative fermentations and for winemakers and brewers who wish to control inorganic nitrogen levels themselves. 50 pounds

Ampersul
Ampersul (ammonium persulfate or ammonium peroxydisulfate - (NH4)2S2O8 ) is a strong oxidizing agent, which provides an effective and selective killing effect against bacteria present in liquid yeast. The ability to kill bacteria is greater at low pH. AMPERSUL is normally used in conjunction with acid in "washing" pitching yeast to selectively kill off any contaminating bacteria. The combination of acid and AMPERSUL provides more effective treatment than the use of acid alone. When added to liquid yeast, the AMPERSUL begins to decompose, releasing extremely active oxidizing intermediates such as ozone, which bring about the actual bactericidal action. Within a relatively short time the ammonium persulfate and its intermediate oxidizers completely react with various compounds in the yeast slurry, leaving no residual behind when the yeast is pitched into fresh wort. 50 pounds
