My brew day was yesterday and I did a full boil on a 5 gal. batch. I had a lot of trouble chilling the wort afterwards so I put it in my chest freezer thinking it would help. It took forever! I put a fan in there thinking it might help but nothing. During all this I had the lid to my bucket resting on top but not completley covering it because I was trying to let the steam escape. When I put the fan in there I just took the lid completely off for like an hour and then just gave up. At this time it was around 90 degrees 5 hours after boil and I put the lid on with the airlock and set the temp control to 64. Got up this morining at 6 a.m. and pitched my yeast. So I pitched my yeast 12 hours after I stopped the boil. I've read about no chill brews turning out ok but what about me leaving the lid off before I gave up and let it sit overnight? Is there a chance for infection here. I have damp rid in my chest freezer and I do spray it down with Star San here and there.
