I have 5 gallons of beer in my primary 6.5 glass carboy. I used California Ale Yeast which ive been keeping at about 68 degrees and it fermented well for 3 days, its now been 10 days since i pitched, the fermenting seems to be done. I dont have a scondary to rack to, but should i lower the temperature for the next week or two while i let the beer clear?
