I was pulled away from my brew last night to go out. I finished the boil and left out the kettle, covered, in the garage at 45F. When I got home, I transferred it to my chest freezer at 43F and this afternoon the wort was down to 66F. It will probably take a few more hours for it to get down to ~48F so I can pitch the yeast.
So, if covered in my chest freezer, how long is too long before pitching the yeast?
I opened the lid to aerate about an hour ago and two other times to take the temperature. It’s only down to 63F now, but I remembered that I had two large iced tea containers with frozen water in my freezer. Your trick Euge! Your post reminded me, thanks! 8)
Got it down to 54F in a little over an hour. Had to transfer and pitch as we are going out to dinner. I figure 54F down to 51F is not going to hurt much, especially since I pitched over 700B cells…
It depends how clean your wort is. I once had to leave some wort sitting at room temperature for days while I replaced a chest freezer (it was a lager and I didn’t want to pitch too warm). No infection. Some bacteria can be slow to take hold, though, so if it seems okay after fermentation, keep it cold and drink it fast.
