Is it okay to have a low temperature (about 10℃) when yellow rice wine is fermented?

When the temperature is set at 10℃, rice wine can be produced completely, and the quality is better (because there are few miscellaneous bacteria, the wine is not easy to be polluted), but the fermentation speed is slow. Note: 1 Keep the temperature high when cooling; (called normal temperature fermentation) 2. Increase the amount of koji by 20%. 3. Use chaff, straw and cotton wool to strengthen the heat preservation of fermentation tank.
