It’s science! Green bottles don’t provide much protection

We’ve talked before about lightstruck beer and about  about how ultraviolet (and even visible light near that end of the spectrum) react with a compound in hops to produce a chemical with many of the same properties as a skunk’s spray.

We’ve also mentioned that green bottles don’t offer much more protections than clear glass, presenting as our evidence the fact that I have never had a Heineken from a bottle that wasn’t skunked.

Well, now there’s some science to back me up.

Rhett Allain, an Associate Professor of Physics at Southeastern Louisiana University, did some experiments with different bottles and some expensive equipment.

As you can see, the green bottles are barely better than clear glass at virtually all wavelengths.

If you love your beer (and unless you like the taste of skunk) get your beer in brown bottles. Even better, a lot of craft brewers are putting their beer in cans nowadays. Even better, pop on down to your local beer-serving establishment and have some beer on draught with your friends. (Heck, have some with your enemies too.)
