METHOD OF USE
- Dosage: from 50 to 100 g/hl, increasing the dosage of yeast in difficult and high gravity fermentation conditions.
- Rehydration method: Rehydrate the yeast in 10 times its weight in clean boiled water at 25-30°C in a sterile container.
- Make sure all the yeast is in contact with the water, leave it for 15 minutes and then stir gently for complete rehydration. Leave it for another 5 minutes at 25-30°C. The rehydration process should not exceed 30 minutes to avoid damaging the viability of the yeast.
- Inoculate the rehydration yeast into the fermentation vessel. The temperature difference between the wort to be inoculated and the rehydration yeast should never exceed 10°C
