My last batch had dripping rain off the trees while chilling. Also had an unsanitized digital thermometer fall into the chilled wort. Things happen when you teach a new brewer ya know. Covered the BK with foil when I started chilling to keep the rain from dripping in. Hey don't take the foil off while I get some things organized ok. He answered OK, came out and his face was looking in the kettle.
He said, " I couldn't help it, it smells so good." Not the first time things have fallen in the chilled wort and all have been fine.
