I did an experiment with beer in green bottles, left a bottle of beck's out in light over night, one in light for a half hour, and kept one covered in the box. Within the half hour, you could already pick up skunky flavors, the one left out over night smelled like a cypress hill concert.

Also noticed that its not just sunlight that skunks beer, but artificial light will do it as well.

I read somewhere that fluorescent lights skunk beer but incandescent lights don't. What kind of lights did you use?

I have noticed skunking of a good craft beer after only 15 minutes in the sun. I poured the can into a glass. Lesson here: drink canned beer from the can.

I just had a beer come out skunky about two months ago. It was horrible and completely undrinkable. I let it set in the keg for about a month before I tried it again. It got better, and now its at least drinkable. I won't serve it to any of my friends (except the one who likes hiny), but its still beer...

Surprising as it is it, it only takes a few minute exposed to direct sunlight to skunk a beer.

Try it for yourself. Buy yourself a 24oz can of Budweiser (or you're favorite lightly hopped macro brew) and pour it into a glass. Take a good sniff and note the lack of almost all aroma (specifically hop/skunk aroma). Leave it outside on a bright summer day for about 10 minutes and take a sniff again. Skunk!

I see two problems:

1. Fermenters in garage means they were not climate control and you are fermenting at a fluctuating temperature.

2. Sun light contact everyday.

Solution:
Put your fermenters inside with a blow off valve (had a carboy explode in my closet) and wrap towels around it securing with a string,bungie,ziptie,etc.

I've got 99 skunk problems but I can't figure out the source. Removed all my bottles from potential sunlight damage source, and it's not even consistent within a single batch - ie. the first few from this crate were great, but the one I'm having tonight is rank. Refrigerating seems to make it worse?!
