I want to try BIAB with a 9% Belgian triple . There would be 14-16 #s of grains in the mash. I plan on a pulley system to drain. I need advice on which available bags will hold up under that amount of weight. I'm guessing 30 #s or so at the end of the mash. I don't want it ripping apart and spilling all over the floor.

I have researched "BrewBag" as a good buy for a very strong bag. I'm looking for first hand experience.

This is a 6.5 gallon pre boil volume.

I just mashed 13lb stovetop. It was heavy, but doable. I have a 1000lb tackle but can't install it in the kitchen
My kitchen colander sits over a 5 gal bucket perfectly to set the grain bag in after most of it drains, and squeeze out some more.

What brand of bag did you use?

Generic cheep bag from BIY. I got it to just try out BIAB as few times before I move to singled vessel electric. It had also doubled as a giant hop bag as few times

Cheap and strong as ever. I ALMOST went this route, but have yet to even work on the project at hand in months.

Both the bag by Rex Slagel "Brew-In-A-Bag" and the one by Mike Wilser "Wilserbrewer" are good bags. I went with the latter as I though all the extra straps on the Rex bag would get in the way with the keggle I use for my eBIAB setup.

Honestly, though, it you are handy in sewing or know someone who is, then you can make one for about $5. I used a voile curtain from Wal-Mart $1.50... and some bungee cords when I was still mashing in a cooler.

As far as going "big" another completely valid way of doing that would be to do a partial mash as well. Maybe consider that. But my keggle Wilser-bad could easily handle 25 lbs of grain-- if it would fit in my pot.. not sure.. the voile fabric itself is extremely strong as long as you don't burn it or snag it.

One other comment: You can always have more than one bag made for you (or make it yourself) if you can't rig up a pulley or other concoction. The pulleys that Wilser supplies are literally ratcheting tie down straps from Lowes...

Thanks,
I use a 10gal. Rmaid cooler. Cleaning up the mash tun and disposing of spent grist are two tasks that I wish to streamline (especially in winter) . The articles I read all warned of bags failing and I wanted to poll local users.

a 15 gallon vessel, minus dead space for a false bottom (3 inches ~= 2.5 gal) and minus a little space on top (2.5 gal) leaves you about 10 gallons of space, which, dry, would probably fit 45lb of grain. That's not leaving much volume for liquid, of course.
(Basis of estimate: 50lb sack of malt nearly fills 2 5gal buckets)
Sounds like a easy experiment: how much malt can I fit in a BIAB keggle. Getting it out while wet may be a different question, sice keggles don't have straight walls

There are manufacturers [ss brewing among others] who estimated grain usage at various grist ratios. May be good for an approximation...

You can use brewing software to estimate volume of the grist mixed with water too. It even has that in the old Promash I still use.

For you BIAB folks, have you seen the false bottom screens to keep your bag of the bottom of the kettle. Good for gas or electric.

Saw that a week or two ago, looks like it fills a good niche in hardware/price -- before this other e/BIAB-targeted stainless false bottoms were in the $100+ range

Almost bit and ordered, until I measured my boil kettle - this screen is way too big in diameter for it.
