Wash temperature is very important.
If the wash is too hot, the yeast may be killed off or weakened, and therefore may not be able to ferment out all of the sugar.
Don’t forget that in warmer times of the year, use a temperature-tolerant yeast such as Still Spirits Heat Wave.

At lower temperatures, the wash will take longer to ferment, or in extreme cases, it may stop working altogether.
It will start again as the temperature rises, yeast only goes dormant in the cold.

If you are fermenting in a hot climate, an air-conditioned environment is obviously ideal.

Temperatures over 40°C could prove fatal during the fermentation.
