White Labs Servomyces Yeast Nutrient Capsules

White Labs Servomyces is a professional-grade yeast nutrient designed to improve fermentation quality in beer, wine, mead, and cider. Developed through research at Weihenstephan, this nutrient supports stronger yeast growth, improved viability, and more efficient fermentation. Each pack contains six capsules formulated for five-gallon batches, offering a consistent way to enhance yeast performance across a wide range of fermentations.

Servomyces provides measurable benefits during active fermentation by helping yeast absorb essential minerals more effectively. This supports cleaner fermentation profiles, increased attenuation, and reduced production of off-flavors such as diacetyl and sulfur compounds. The result is a more controlled fermentation that develops clarity and stability while maintaining intended flavor characteristics.

The nutrient is compatible with ale, lager, wine, mead, and cider strains and works reliably in both high- and low-gravity environments. Its encapsulated format allows for easy dosing without the need for measuring or additional equipment. Brewers use it to promote strong starts to fermentation, maintain yeast health through challenging conditions, and shorten total fermentation time.

To use Servomyces, add one capsule to a five-gallon batch during the last minutes of the boil for beer, or open the capsule and add the contents directly to wine, mead, or cider musts. The nutrients dissolve quickly, providing yeast with improved access to minerals that support efficient sugar conversion and healthier fermentation outcomes.

Designed for home and professional fermentation, White Labs Servomyces offers a reliable way to strengthen yeast performance, improve consistency, and support clean, controlled fermentations across multiple beverage styles.
