Stage 7 - Fermentation

The fermentation tanks hold the cooled wort extract, and the yeast is added (pitched) into the brew. After 12 hours fermentation begins, and will proceed for 4 to 7 days until all the sugar is converted into alcohol. The temperature of the fermentation tanks is controlled to the optimum temperature for yeast growth. After fermentation, the yeast is harvested from the bottom of the fermentation tanks, to use for the next fermentation.
