Liquors exposed to direct sun light
We have a semi-favorite local restaurant that we visit on occasion...
Yesterday, while waiting for a traffic light to change, I glanced at this restaurant's facade and noticed that it's back bar was directly exposed to the street through a large window. Sitting in the window was a significant selection of bottled, premium vodkas.
This made me wonder: Will prolonged exposure to sun light affect bottled liquor?
The flavors in your booze, either naturally there thru fermentation and aging, or added (as in flavored Vodkas), are all delicate and should not be exposed to high heat. As for sunlight, the same goes, naturally colored liquor / liqueurs are susceptible to light oxidation and color and flavor will usually go off in with prolonged exposure.

Thank you for your responses, JK and Papa Kip. Blowing up a Fifth of Bombay Sapphire is a tragedy of cosmic proportions!
Next time I visit this restaurant, I'll make a comment to the tender on duty that the place is not doing their liquors justice, exposing the bottles to prolonged sun light.
Generally, no. Lower proof fruit liqueurs are more delicate, and can break down with application of light and/or heat. I think about the only thing that will happen with vodka in a window is it could blow its top if it got hot enough. I've accidentally done that with a bottle of Bombay Sapphire that I inadverdently left in my car on a Phoenix summer day.
