Servomyces™ is a naturally enriched single-strain brewing yeast that is used as a biological yeast nutrient. The propagation and drying process of Servomyces™ has been specifically designed to accumulate a range of trace minerals and elements that are essential or limiting during alcoholic fermentation. Servomyces™ is an active, naturally zinc-enriched Saccharomyces cerevisiae yeast that contains between 50,000-60,000ppm of zinc within its cellular structure. The name Servomyces™ is derived from the fact that the active yeast is added to the kettleas a sacrificial ‘zinc-bearing’ yeast to serve the chosen fermentation yeast. All-malt wort should normally provide most of the necessary quantity of nutrients for a successful fermentation. Zinc, however, can still be deficient. Servomyces™ is added at the end of the boil to inactivate the yeast while keeping the zinc in the cellular matrix. The zinc derived from Servomyces is therefore considered to be more bioavailable compared to the addition of mineral zinc. Servomyces™ is highly recommended for propagation and repitching, and can be used as a ‘yeast insurance’ to ensure beers will ferment and attenuate to your expectations. Since zinc is necessary as an enzymatic cofactor in the last step of alcohol production, it is highly encouraged to use Servomyces™ for high gravity fermentations. Benefits: Can decrease fermentation time significantly Improves yeast sedimentation Stimulates uptake of maltose and maltotriose, depending on the brewing strain, which results in higher alcohol yields Stimulates protein synthesis and yeast growth which leads to higher biomass production during propagation Eliminates harsh sulphur notes and produces a smoother more balanced beer Form: 10 capsule blister pack - 1 capsule per 4-26L 500g sachet - enough for 500 hL / 500 US BBL of Beer MICROBIOLOGICAL PROPERTIES Classified as Saccharomyces cerevisiae, a top fermenting yeast Typical analysis of Servomyces per gram: Percent solids 93% – 95% Zinc 50,000 – 60,000 ppm Wild Yeast < 103 (Lysine method) Bacteria < 105 (0.01% of yeast) Mold negative Contains inactive brewer’s yeast. Does not contain GMO materials. BREWING PROPERTIES Minerals, when incorporated into some sort of living tissue, are more efficacious than when presented as a salt. Servomyces presents better bio-availability of minerals, which is a very important factor in yeast nutrition. Servomyces can decrease fermentation time significantly. Improves yeast sedimentation. Stimulates uptake of maltose and maltotriose, depending on the brewing strain, which results in higher alcohol yields. Stimulation of protein synthesis and yeast growth which leads to higher biomass production during propagation. It is reported that Servomyces eliminates harsh sulphur notes and produces a smoother more balanced beer. USAGE Re-pitching Propagation High gravity brewing Add to kettle about ten minutes before the end of boil. 1 g Servomyces is used for 100 liters of wort for fermentation. 2 g Servomyces is used for 100 liters of wort for propagation. Practical trials have shown that addition of Servomyces should be made to the kettle about ten minutes before the end of the boil. Storage: Servomyces should be stored dry and the packaging should remain intact. Technical Data Sheet: lallemand-tds-yeastnutrients_Servomyces
