White Labs Yeast Nutrient (WLN1000) – 1 oz
Boil-added nutrient blend for healthier yeast and cleaner fermentation
White Labs Yeast Nutrient (WLN1000) is designed to improve yeast health and support clean, complete fermentations. It is commonly used to boost fermentation performance and repitching reliability, and it can be especially helpful when the grist is not 100% malt (for example, recipes with sugars or adjuncts).
Taste and Character
- Cleaner results: Supporting yeast health can reduce stress-driven flavors and help you land a smoother finish.
- More consistent fermentations: Helps keep fermentation timelines and attenuation more predictable, especially in demanding recipes.
Where It Shines
- High gravity ales and lagers where yeast are under greater stress
- Adjunct and sugar-forward recipes where nutrient levels can be lower than all-malt worts Source
- Brewers harvesting and repitching yeast who want stronger, steadier performance across generations Source
Role in the Brewhouse
- Comprehensive nutrient support: White Labs describes this blend as containing diammonium phosphate (DAP), essential vitamins and cofactors, nitrogen, amino acids, proteins, peptides, and minerals. Source
- Fermentation and repitching support: Used to increase yeast health, helping fermentation and repitching performance. Source
- Simple boil addition: Added during the boil so it is sanitized before it reaches the fermenter.
Brewer’s Guidance
- When to add: Add during the last 10 minutes of the boil. Source
- Typical dose: White Labs lists 1 tsp (5 g) per 5 gallons (20 L). Some retailers summarize homebrew use as 1/2 tsp per 5 gallons. Start with the manufacturer guidance, then adjust only if your process calls for it. White Labs MoreBeer
- How to use: Measure the amount you need and add directly to the kettle. Stir to disperse.
- Best results: Nutrients help most when paired with good fundamentals: healthy pitch rates, appropriate wort oxygenation when needed, and steady fermentation temperature control.
