Servomyces is a nutritional yeast supplement (GMO free) that was originally developed for German brewers by Weihenstephan and the Munich University. It conforms to the restrictions of Reinheitsgebot. Servomyces enables any yeast strain's ability to incorporate essential nutrients into its cellular structure. Tested in breweries around the world, it has been proven to cut down fermentation time and increases flocculation. Also, greatly reduces harsh sulfur notes and improves the health and viability of yeast. Servomyces reduces levels of diacetyl at the end of primary fermentation while producing faster, more complete attenuations. Recent developments have made Servomyces available to homebrewers and home winemakers. Each retail packet contains 6 capsules, which can each be used for a 5-gallon (20-25L) batch. Servomyces can be used in all fermentations, including beer, wine, cider, and mead. 6 capsules per package.
