I am brewing an amber ale. The instructions I have say to store the carboy (to which I racked the beer from the primary) in a cool and dark place. How dark should it be? I placed the carboy in a corner that gets indirect sunlight that is not intense at this time of year in the winter. There are shades on the window that while allowing some light through, they decrease the intensity of it. Is it OK not to cover the carboy in this case?
Also, while the instructions say to keep the carboy in a cool place, I read on the forums that it's OK to keep it at the same temperature the primary was in (65-75F) because there might still be some light yeast activity. I will keep the beer in the carboy for 10 days. Does the recommendation of keeping the secondary fermenter in a cool place apply more for carboys that are kept for a longer time (longer than 2 weeks)? I'm planning to keep it in the same room at 70 degrees.
