yeah it was pretty casual for an experiment...what happened was i poured a beer and actually forgot to drink it, so when i got up the next day instead of tossing it i put it in my window which faces south-west. The sun was really bright that day, so i just wanted to see how long it would take...
i remember when i was like 13 yrs. old i stole a case of heinekens from somewhere and i stashed them in the woods behind my house, a week later me and my friend went to drink them and oh boy were they skunked!
My question is, when are hops susceptible to this? They grow on the vine in bright sunlight, but is it as soon as there picked their vulnerable? or after they have been boiled?
