Why liquid yeast for lager
Lager fermentation demands healthy yeast with full nutrient support. Fresh liquid yeast, cold-side zinc, and proper repitching management deliver faster starts, cleaner profiles, and consistent performance across generations.
- Faster fermentation starts at low temperatures
- Cleaner flavour profiles under cold fermentation stress
- Consistent performance across repitch generations
- Improved tank turnover
The nutrient connection
Every boil destroys nutrients. Every repitch compounds the loss. The Bluestone Nutrient Booster range restores what the boil takes out:
BSY-N01 Zinc Booster
10 mL/hL cold-side. Targets 0.2 ppm wort zinc. Less than 1 cent per litre.
View product
BSY-N03 Vitamin Booster
10 mL/hL cold-side. Restores B-complex vitamins lost during boiling.
View product
BSY-N04 High Gravity Booster
Use instead of Vitamin Booster for high-gravity lagers and worts above ~1.070 OG.
View productRepitching economics
A 2L pitch of Bluestone lager yeast repitched 8 times spreads the yeast cost across 9 batches. Combined with our Clean Repitch System and Nutrient Boosters dosed on every batch, this is the most cost-effective way to run a lager programme.
Our Repitching Technical Guide covers harvest timing, storage protocols, viability tracking, and generation management in detail.
