[quote=“learningmore”]Usually the temperature affects how the yeast produce and replicate. When the beer is cold, the yeast will go to sleep into a dormant stage.
Wide temperature swings are not good for yeast, so it isn’t recommended to have a temp range of more than 5 degrees.
People sometimes do a Diactecyl rest by bringing the beer up to room temperature to cause the yeast to clean up any off-flavors from fermentation.
Then,people common “cold crash” their beer when the fermentation is done to cause the yeast to drop to the bottom. Usually bringing the temp of the beer to 40 degrees (unsure how low people go) for a day or two will cause the yeast to go dormant.[/quote]This is true but the OP was asking about hops, not yeast.
