White Labs Servomyces Capsules (Pack of 6)
Yeast nutrient for healthier fermentation and cleaner beer
Servomyces is a yeast nutrient produced by White Labs that helps provide yeast with bioavailable zinc during fermentation. Zinc is an important trace element for yeast metabolism, and adding Servomyces can support strong fermentation performance, improve yeast viability, and encourage cleaner flavor profiles – especially in higher gravity beers, low nutrient worts, and repeatably reused yeast.
Taste and Character
- Cleaner fermentation profile: Supports yeast health to help reduce stress-related flavors.
- More consistent results: Helpful when you want repeatable fermentations across batches.
Where It Shines
- High gravity ales and lagers
- Beers fermented with lower nutrient worts (high adjunct, very light base grists, sugar additions)
- Any batch where you want to support yeast performance and reduce the risk of sluggish or stalled fermentation
- Brewers harvesting and reusing yeast who want to support vitality and consistency
Role in the Brewhouse
- Supports yeast metabolism: Provides a form of zinc that yeast can readily use, supporting healthy growth and fermentation activity.
- Improves fermentation reliability: Can help yeast reach terminal gravity more consistently when conditions are challenging.
- Helps with yeast health over time: Useful for yeast repitching workflows where vitality and clean performance matter.
Brewer’s Guidance
- When to add: Add to the boil late so it is sanitized before fermentation. A common practice is adding it with 10 minutes left in the boil.
- How to use: Drop a capsule into the kettle and allow it to dissolve and mix in. If desired, you can open the capsule and add the contents directly.
- Dosage approach: Use one capsule per typical homebrew batch unless your process specifies otherwise. For very large batches, scale proportionally.
- Do not overdo it: More nutrient is not always better. Use the recommended amount to avoid unintended flavor impacts.
- Pair with fundamentals: Nutrient helps, but best results still come from healthy yeast pitch rates and steady fermentation temperature control.
