FERMENTATION SCHEDULE

7-10 days at 18 deg c. Then raise at 1 deg c per day until you reach 21 deg c.
You must ensure that you have a consistent FG for 3 days before your beer can be deemed finished.
For the best results give your beer some extra days in the fermentation vessel so that the yeast can clean up after itself.
There really is no rush!!
