evap rate during boild sub zero temps

wicked cold here and getting colder. with sub zero temps and wind chills -10 to -30, whats the expected impact to evaporation rate during boil…if any?

Methinks you would get a higher boiloff/evaporation rate.

You are a brave man, brewing at those temps.

i assumed that, but 75 min into 90 minute boil and right on track for evap rate.

Would it be inappropriate to gloat over 65F today. Brewing in shorts in the sun. :wink:

grrrrr  >:(

How’d it go, Ken? Did the super cold temps affect your boil off?

I’m always interested to know how things go. It adds to my knowledge base without having to experiment myself. Thanks.

No not a bit

Move south man! You can ride year round down here… Except for those few weeks in August  when the asphalt melts. Brewed today in lovely 70 degree weather!

Isn’t boiling temperature 212 no matter what the ambient temperature is? Unless you’re in Denver, of course.

boilg temp , sure. but i was wondering with the extreme cold and wind chills, if evap would increase.

Ken - no change at all?  I have noticed that humidity (lack thereof) has a little higher evaporative effect overall, but just a bit.

I don’t think ambient temperatures would have any effect. 212 is 212. Ambient pressure would have more of an effect I would think. But then that might just have effect on boiling point.

It sure looks like it’s blowing off more steam in the cold, but I think it’s just more visible when it’s -5 degrees than when it’s 95 degrees. What’s more mind boggling is how one location can have those same temperatures only several months a part lol.

You had me right up until “when the asphalt melts”!

Yoopers don’t “do” hot weather but I’m not crazy about the cold either.

One thing I’ve found is that I do boil off a lot more in the winter where I live.  However, we are in a fairly dry climate.  In the winter, the inside of my house reads 20% humidity on my hygrometer.  I boil off 2 gallons/hour then, while in the summer it’s more like 1.25 gallons/hour,

Yeah, there’s not enough baby powder on this planet to get me to move to the south lol

^^^^^This is what i was thinking

Well said.
