biab-10 gallon batches? - Page 2

70L pots work really well for 10 galon batches. No need for a sparge, and worst case you just top up a little to your preboil volume.

They work well for single batches too, where as much larger doesnt

I haven't made a 10 gallon batch yet, but my last brew had 18 lb of grain. There would be no problems using 25 lb like a poster mentioned with my setup, click on link below.

Are you planning on getting a bigger pot?

I do 10 gallon BIAB in a 15.5 gallon Keggle (62 qt), and do my 5 gallon batches in an 11 gallon kettle (44 qt).

My starting water volume on my 10 gallon Citra APA batch last weekend was 13.6 gallons for 20 lbs of grain, and everything fit just fine with a good bit of room to spare. 19 lbs of two row and 1 lb of honey malt displaced about 1.6 gallons, so I was up around 15.2 gallons (including the displacement) of the 15.5 during the mash, then back down to around 12.5 gallons pre-boil for around 10 gallons post boil.

That's about what you need for an average gravity batch (this APA ends around 5.6% ABV).

Hope all that helps!

Do you use any sort of pulley system to get your grain bag, or do you just beast mode it?

I'm thinking of doing a 7.5 gal BIAB to break in my new equipment so that I can split off 2.5 gal and ferment it with a different yeast. My pot would be 15.5 gal size, so I know I'd have plenty of room, just wondering what I'll be getting myself into as far as how much of a PITA it is to lift all that.

I pulled the bag myself, but I didn't suspend it to drain.

My smaller 11 gallon kettle is one of those Bayou Classic kettles that has a removable perferated basket, so I pulled the grain bag out of the 15.5 gallon keggle and put it straight into the perferated basket that was in my 11 gallon kettle. I then took a lid from a kitchen pot and applied pressure to the top of the grain bag so the wort drained through the perferated basket and into the 3" of space in the bottom of the 11 gallon kettle. Then just poured back into the keggle.

So you might have to get a little creative, but there are easy ways to get the desired result!

I did a 22 pound grain bill on a 10 gallon batch in my keggle. Worked fine although I did scoop out some of the grain and put it in a separate bag to make it easier to drain and squeeze.

For a 10 gallon BIAB, a 20 Gallon pot would be ideal IMO. Oh and while a pulley system looks kind of neat, a simple hook in the cieling, and rope wrapped around the hook will allow you to pull and hold the bag fairly easily.

If you are looking for a super well made bag that will hold more wet grains than you can fit in it look no further than the previous poster! I bought a bag from him for my first 10 gallon batch in my keggle (19.6 lb grain bill). It was a tight fit for the water but, everything fit with no problems. My boil off was a little more than expected and I had to top off an extra gallon.

Hey Smokewater....do you start with 5.5 gallons of water in what size pot? How quickly does the absorption from grains occur if you add them slowly and stir? Say about 12 pounds.

I did a 6 gallon batch in my 5.5-6 gallon turkey fryer biab. I sparged the grains and drained after the mash and had around 5.5 gallons. I added about 1 gallon to the mash due to the absorption. I also added about 1/2 gallon to the fermenter to bring to 6 gallons. Not sure if that will water it down??? I will see in about 2 weeks.
