Its been about the same here too. I think I will brew this coming weekend despite the cold weather. Chill times should be cut in half thoThe high here in Wichita yesterday was 25F.
It wasn't too bad except there was some water left over in my supply hose from a previous brew day that froze while my hose was hung up. I had to bring it inside to thaw it out, so I was lugging kettles of water to the garage from inside to start the day.
