Sounds about right...just spitballing here, but you could mash in a touch low on volume, and max out the kettle w/ a hot water addition after the mash to give you plenty runnings for a 3 gallon batch....w/ 4.5 gallons initial water you will be close to overflowing the pot...I suggest mashing in a little low on water and adding hot water after the mash...stir and stir then pull the bag.

I agree. This is what I did for my first batch (5.5 gallons batch in 32 quart kettle).

I mashed with about 4 gallons IIRC, and after mashout I topped up to 6.5 gallons.

ok guys, I'm thinking of going BIAB from all extract for my next brew (queue drums and fanfare)... was going to try the all grain Chinook IPA kit from Northern brewer pre-crushed grains etc... now I only have a 7.5 gallon pot that came with my Bayou burner... do I have enough volume in that pot do do BIAB or should I hold off till I have a bigger pot??? (volume is 10 lbs of 2-row and one pound of carapills)

Never did that big a batch, but I've mashed 7 lbs of 2Row in a 5 gallon cooler so I think you'll have no problem. I'm sure someone brighter than me will kick in soon.

Oh, that was NOT for a 5 gallon brew. I think I did 3 gallons.

You won't have enough volume if you're trying to mash with the entire volume. I have an 8 gallon pot and yesterday I mashed 9 pounds of grain at 6 L / kg (2.88 qt / lb) for a mash volume of ~6.5 gallons and my pot was full. Really full, like less than a half-inch down from the rim, so there's no way you're going to fit 6.5 gallons of water and 10 lbs of grain in a 7.5 gallon pot.

However, there's no reason why you couldn't mash with 5.5 gallons or whatever will comfortably fit in your pot and then top off with the extra volume before the boil. For instance, according to Brewtarget (which was pretty accurate for me with this last mash), a ~5.9 gallon mash will give you a total mash volume of 7.1 gallons (which should fit comfortably in your pot and will yield about 5 gallons of wort, in which case you can top off with a gallon of water (or whatever you need for your boil off rate) and be fine. That would be mashing at 4.9 L/kg (~2.3 qt/lb).

Sure, I just brewed a Scotch ale with 13.5 lbs of grain in a 7.5 gallon pot for 5.75 finished gallons (FG 1.073 with 1 lb of DME added). I suspend the grain/bag after mash and 170F mashout by a fryer basket and rope/pulley. Then drip 1-2.5 gallons of sparge water through there.

I certainly would not recommend this large of a mash right away, but 11 lbs is doable. Generally I get better efficiencies with the standard 7.5-9 lb mash (mid 80 %). With the 11-13.5 lbs I get ~ mid 70%'s.

Do you mill your grains finer than standard all grain?

I am very curious how you can fit that kind of volume. As I said, my larger pot was full with a smaller volume of grain, and that was crushed very finely. What is your secret.

Yeah my grain is probably a little finer than std. Not terribly so though. I double bag my grain. A coarse paint strainer bag inside a fine voile bag, which does reduce the trub by 1/2 gallon or so.

As to higher grain amounts, I just mash at a lower grist ratio. That one was mashed at around 1.4 qt/lb. It does lower the efficiency some I guess.

Theres no getting around the fact that larger kettles make BIAB easier. I have my eye on a nice 15 gallon stainless, but haven't gotten the fundage approved by the boss yet
