For those of you who use Sanke kegs to boil, what evaporation rates are you seeing (gal/hour)? Looks like I'm hitting about 2.4 gal/hour with mine. |

I've been getting about 1.5-2 GPH boil off rates and that's without a strong boil. |

Mike,
When starting with 12-13 gallons in a 1/2 barrel Sanke keg, I get evaporation about 1 gal per hour, once a medium rolling boil begins.

The evaporation rate for my converted Sanke keg is 1.3 gallons per hour with a moderate to full boil. Your rate will vary depending on the burner and how vigorous is the boil, but once you know it you can factor it into your calculations. |

I'm curious as to how vigorous of a boil you guys are using to get 2+ gallons of boiloff... I get about 1.25-1.5 gallons / 70 minute boil. That's in 3 different kettles: a 20g, a 15g Polarware and a 10g kettle. I typically bring the wort to a very vigorous boil at first then backoff to a medium rolling boil when i add the first hops. |

I get at least 2 gallons in 70 minutes. Last batch I started with 6.25 gallons and ended up with 4 gallons in the fermenter (Well 5 gallons but about a gallon of it was trub and hops).

Pacman, I don't think I boil any more vigorously than anyone else. I crank it up to get it going and then throttle it back to probably about 1/4 on the regulator. I was shocked too when I did my first boil and found I lost that much, but it's been pretty consistent since then. I started with 8 gal and ended up with 5.5 on my last batch for a 60 minute boil.
This was a big reason I had to build a bigger tun. I was using a 5 gallon one and I wanted to batch sparge. Since I wasn't able to get 4 gallons out of each charge in a 5 gallon tun I had to do 3 charges. Since that takes as much time as fly sparging I built and used a 56 qt tun on my last batch. |
