Add servomyces to your beer to increase yeast health because healthy yeast make better tasting beer. Other benefits include a decrease in fermentation time and increased alcohol potential. Servomyces stimulates the uptake of maltose which results in drier beer with higher alcohol yields. It is made by saturating beer yeast with zinc and then drying it. Zinc is a missing nutrient in wort and is more readily absorbed from dead yeast cells than by adding it directly as a mineral. Originally available only to professional brewers, this wonderful yeast nutrient is now to the homebrewing community, thanks to White Labs and Lallemand. Since it's introduction, we have been after White Labs to make a smaller, more easy-to-use version of the product. It wasn't until our very own Shea Comfort came up with the capsule idea that they were able to move forward and deliver this "super food" to us! Olin Schultz of MoreBeer did an intial side-by-side trial batch using "Servo" and found the beer with servo started faster, fermented quicker, and finished 1 gravity point less than the control batch. While it is not a cure-all pill for your brew, it offers the serious home brewer an easy, effective way to help ensure yeast health. Servomyces was developed in Germany at the Weihenstephan brewing school and the Munich University, so of course it conforms to the German Purity Law! Contains 6 capsules good for 5 gallons of wort each. Add Servo in the last 10 minutes of the boil. If your ferment does not require a boil ( as in a mead), open the capsule and add the Servomyces directly.
