BIAB Double Batch in a Turkey Fryer?

[qualitypunk]

Hi!
Been lurking on the forum for a while and haven't yet encountered an answer to this question. Figured it's time to join!

Let me preface this by saying I only have experience with Extract so far.

I am close to attempting my first BIAB and am looking forward to it. I'm hoping that I can accomplish the same results that I had previously with extract brewing. In my last couple extract brews have doubled the ingredients/quantities of an extract recipe in a 9 gallon turkey fryer and then split the wort between 2 primary buckets, topped up with water and ended up with 10 gallons of beer in the same time it normally takes to make 5.

Is this possible when doing BIAB?

I have a wilserbrewer bag which I expect would support the weight of the grains. Is there any reason why I shouldn't try this?

Thanks!!

I would have some DME on hand as your efficiency may be a little lower than normal, but it'll work. Just treat it like a big partial mash.

I have a keggle and BIAB - I can do 10 gallon batches of low gravity pretty easy. This is when I wish for more burner.

As with maxing out most setups, it's going to take a little longer to boil, it's gonna use more gas and the odds of a boil over are going to go up.

Yes, I think this can be done. You will need to sparge to fill the kettle. You can also consider reserving a gallon or so of wort and adding that as the boil goes down, be sure to boil for at least 20 - 30 minutes after the last wort addition.

The sparging will be key, you can either sowly pour water over the grain, or dunk the grain bag in another large bucket, cooler, kettle etc.

I would not try this for your first AG batch, but would think it wise to put some mileage on the tires first and do a couple 5 gallon AG batches first....no harm in trying it, just check gravity before adding top up water...worst case you'll easily net 8 gallons rather than 10.

Can't wait to hear how this one turns out. If you're successful I'm gonna give it a whirl. Heck, even if you're not successful I might try it any way.
