Dear Dr. Vinny,

I know sunlight has an adverse affect on wine. How about fluorescent lighting?

—Sandy, Los Angeles

Dear Sandy,

Ultraviolet rays from any light source can prematurely age wines. That's why most wines meant for aging come in colored bottles, to give them some extra protection (and why wines best consumed young are often in clear bottles). It seems that incandescent lights are a bit better than fluorescent lights (which are a bit better than warm sunlight), but for long-term storage, it's best that you don't expose your wines to any constant light.

—Dr. Vinny
