How many batches per propane tank?
 
I was wondering how many batches you guys think you can do on a standard grill size propane tank on an outdoor burner?

I honestly don't know as I always make sure I have a full backup. I think at least three though. Of course burner, batch size, process (AG, extract, full-boil, 1/2 boil, sparge, etc.) will vary quite a bit.

this is covered multiple times on here... it depends on burner size, rate of boil, and if you use it to heat everything or to just boil. search is really the key here...

A lot depends on how long your boil is, how much you use it to heat the water before each step, etc... Plus, how much wind you have to deal with on that day. I've had as few as two batches from a tank, or up to about 4. Last batch used about 1/4 of a 20# tank.

I do look forward to the day when I'll be brewing at my own house. I plan to either have a LARGE propane tank, or use natural gas to feed burners.

Crap shoot. I'd guess about 4- five gallon batches on average though. Sometimes when it's cold out I heat my strike water inside on the stove. And to offset that, sometimes I use Pils and do a 90 minute boil. (shrug) I always have a spare too, so I don't keep all that close of a tab on it.

ugh...maybe a half batch w/ a noreaster blowing cold at 40-50 knots...I would get a spare tank or befriend the neighbor and his tank.

I'd have to say I get about 3 batches per tank. SQ14 runs constantly on brew day between heating water and boil. A spare tank is a must.

everything being said here is about what I've experienced. I've had as few as 2, as many as 4. Depends on what's up with that batch.

What size batch? Where do you get your tank filled? How long do you boil? With no more information than you supplied this comparison information is useless. Seeing as how you are a Michigan guy I will tell you that the "Blue Rhino" tanks are filled with 15# of propane. The Ameri gas are maybe 17# If you have a reliable propane refill place nearby you will get 20# fills, cheaper then those gas station "propane in a cage" fills. That being said. For a 75 minute boil I average 2 # for a 6 gallon batch and 5# for a 11 gallon batch. So 8 batches of 6 gallon .... 4 batches of 11 gallon. I currently pay $16.96 with tax for a 20 # fill. I can get cheaper but the drive time and car fuel price makes the one closest to my house the most cost effective.

if your cheap like me at least 12 5 gallon batches. I heat my mash water on the stove, as soon as I mash in I start my sparge water on the stove than I use the propane burner for my 60 minute boil. Also helps to brew in the garage out of the wind.
