Pairs with
Always pair with Zinc Booster. Below ~1.070 OG, use Vitamin Booster instead.
The repitch connection
High gravity fermentations place extra stress on yeast. Nutrient depletion compounds with each repitch, and high gravity worts amplify the deficit. The combination of osmotic pressure, higher alcohol, and depleted vitamins can push yeast beyond their tolerance.
Cold-side nutrient support at pitching restores what the boil removes, giving yeast the best chance in demanding fermentations. Dose on every batch, including repitches.
See our Repitching Technical Guide for generation management protocols.
Works with any yeast
Including dry. No Bluestone account required.
