Description
CS31 is a classic Belgian style season yeast with high aroma intensity and very high attenuation levels due to its diastatic ability. It produces peppery and spicy aromas which are more prevalent at lower fermentation temperatures (<20℃), whereas the fruity expression dominates at higher fermentation temperatures (27℃+). The flavour of CS31 will further develop during bottle conditioning. The diastatic ability of CS31 can lead to refermentation of packaged beer, care should be taken to ensure fermentation is fully exhausted prior to finished packaging into bottles and cans.

Fermentation Profile
Usage
Dosage: 50 to 100 g/hl, increasing yeast dosage under difficult fermentation conditions and high gravity.
Rehydration method:
1. Rehydrate the yeast in 10 times its weight of clean boiled water at 25-30℃ in a sterile container.
2. Ensure all the yeast contact with water, leave it for 15 minutes and then gently stir to suspend yeast completely and rehydrate fully. Leave it for another 5 minutes at 25-30℃.
3. The rehydration process does not exceed 30 minutes. If it is above 30 minutes, yeast viability will be hurt.
4. Pitch the rehydration yeast into the fermentation vessel. The temperature difference between the wort to be inoculated and the rehydration yeast should never be over 10°C.
Storage
Store in low temperature (≤10℃) and dry place, with the shelf life of 24 months.
