Keggle with a banjo evap rate problems!!

Alright guys I'm beginning to use my banjo and I want to know what kind of pre-boil volumes you guys use for a 5.5 gallon batch? I know with my old cheap turkey fryer, I'd get around 10% or so. Does the banjo do the same? Should I start my pre-boil at around 6.5 gallons or should I go higher?


Hey, if you've got the info, how about the pre-boil volume for a 11 gallon batch on a banjo burner with a keggle?

Thanks,
J

I am not a fan of percentage losses because the loss is very subjective...for instance you are in (humid)Houston and I am in (dry)cold ass CO...if we are both brewing outside I am going to lose quite a bit more due to ambiant temps and dew points. That being said, for a 5.5 gallon batch I start w 6.75-7 gals or for a 11 gallon batch, almost 13...you really have to watch boil overs when you are adding hops with a 13 gallon boil....nucleation sites are a *****!

Yeah, you're right. I knew this and should have been more specific. Do you use a banjo? If so, is that the burner you started off with? If not, did you notice a change from your original burner to the banjo? I'm just trying to figure out if I should maybe stick with the pre-boil amount I'm typically used to. I'm going to use my burner soon and already have three batches planned when I get my bulk hops in. I want to stock up for the summer.

Other than a stovetop, this is the only burner I've had (BAYOU from Ace). I think you should stick with your normal amounts for your first batch, then see if you need to adjust. I would assume that any adjustment needed will be very minor.

Good Luck!

I have to start with 7 for my Keggle and turkey fryer burner.

Where do you live? As noted before Humidity and such effect these factors.

oh sorry. Missouri. usually around 70-80 when i brew.

It's not really a percentage you lose. If you boil 5 Gallons and lose 1 gallon to evap and boil 15 gallons, you'll still lose 1 gallon to evap.

Best way to check, throw 5 gallons of water in your keg tonight and boil it for an hour. Measure how much is left Temperature will then effect that season to season.

I'm in Ohio and start with 7 gallons boil to get 5.5 into fermenter. Start with 12.5 to get 11 into fermenter. Regardless it's ~1.5G lost.
Your flame intensity will effect this because of how strong the boil will be. Also hop use will effect final quantities into fermenter through absorption.

For some reason I lose a lot more to boil off in the humid summer than the dry fall/winter. In July it seemed I couldn't get enough wort in the kettle for a 60 minute boil. I could probably boil for 90 minutes now and still overshoot.
