How long should I keep my beer at the recommended fermentation temperature?
For example, I used SAFALE US-05 yeast in my latest batch of beer. The yeast packet says recommended fermentation temp. is 59 to 75-degrees F.
Once primary fermentation has completed, should I turn off my heating system (which consists of a large bin filled with water then heated with an aquarium heater that I place the fermentation bucket into) and let the temp. drop to the ambient room temp, which is currently around 40-degrees during the day and even colder at night?
Or should I keep it at 59 to 75-degrees for a while even after primary fermentation has completed?
