Guys,
I just brewed Yooper's DFH 60 Min IPA clone last night in my brand new 7.5 gallon stainless kettle. I got a late start and finished my boil around 10:30 PM last night. With the temperature dropping close to 0* overnight, I figured it would cool fairly quickly if I put it in my yard, which also has a couple inches of snow on it.
After waiting 3 hours and only seeing the temp drop about 40* I decided to set an alarm for 90 minutes later and went to bed. I did this several times, until the wort was finally down to about 80* some time around 4:30 AM.
I typically chill my kettle in an ice water bath in my utility sink, but the new kettle's too big for that. Chilling has taken me somewhere between 1 and 2 hours every time until now.
So, what's the deal here? Is it that the stainless is a better insulator than the thin walled, enameled canning kettle I've been using? Is it the larger volume (5+ gal. vs. 3.5~)? Is it that air, even at 0* doesn't absorb heat as well as water?
Thanks for any info you guys can provide. I can't afford too many all night brewing sessions like this one!
