I just can't stop looking at my carboy of wort. I store it in a dark closet. However, I can't help but look at it and admire its beauty 3 or 4 times a day (twice that when the fermentation activity is vigorous). Do you think exposing the brew to the 60 watt incandesent bulb in the closet affects the quality much? It does not get exposed to sunlight, just the light bulb.
