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 kettle
as 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
