I’m hoping to NOT find this out the hard way. I homebrew with a standard 20 pound propane tank fueling a Bayou Burner Classic (sexy, I know!) and I’m trying to figure out when I should refill the tank.
I use extract kits, and have done two 60 minute boils on the current tank, each with a 20 minute steep of specialty grains before cranking up the heat. I try to be as economical as possible, using just enough propane to keep the boil going, and have been brewing in sub-freezing temps (in the 20’s to 30’s).
I’m hoping to get one (or two?) more boils off of the tank before I refill it, but I’m afraid of running out mid-boil. Anyone have any idea how long a 20 pounder is good for under these circumstances? Is there a way to weigh the sucker and use math (you know, the adding and subtracting stuff) to figure out if I need to top her off before I brew again?
Please let me know below.
Also, as a big fan of half-measures, I just purchased a Tap-a-Draft system from Northern Brewer and hope to bottle my Two Hearted clone in it this coming weekend. We’ll see how that goes…
