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.

Faster fermentation, improves yeast sedimentation, stimulates the uptake of maltose and maltotriose (which results in greater
attenuation and higher alcohol yields), and stimulates protein synthesis and yeast growth which leads to higher biomass production during propagation.
