Servomyces yeast nutrient is a nutritional yeast supplement (GMO free) originally developed for German brewers by Weihenstephan and the Munich University. It conforms to the restrictions of Reinheitsgebot. It enables any yeast strain to incorportate essential nutrients into it's cellular structure and thus speeds up the fermentation process. Lager beers that would otherwise take 2 weeks to ferment can be finished in about 1 week.

* Add one capsule of Servomyces into wort 10 minutes before end of the boil. If boiling is not required, open capsule and pour contents into wort or fermentor. Dosage is (1) capsule per 1-7 gallons of wort.
