Sorry for being vague. For the stout I made (7-8% abv) the fermentation was more vigorous compared to the normal 5-6% ales. If I was still using the closet for fermentation with it would not have been cold enough to keep the fermentation temperature in the proper range.
I got lucky that I have a Fermentation chamber that uses jugs of frozen Ice and a fan to create a colder environment for fermentation.
