So I was forced to move some beer out of the fermenting room to make room for a house guest and I forgot to cover 8 gallons of porter in glass carboys. They sat in the sun for about 4 hours. Not direct sun but enough to make my stomach turn when I remembered later in the day. A few laps around google leads me to believe that beer can skunk in minutes with enough light. I plan on kegging and bottling and just hoping for the best come tasting time, but I was wondering if anyone has been in a similar situation or knows what the likely outcome is.
