made my own BIAB

So will this work? How's the stitching look?

Oh, and made me a hop sock spider thing too. Super easy.

This weekend, I'm hoping to do my first 10 gallon batch with this. 23lb grain bill.

Looks good. Just bought a big bag to fit my keg at my LHBS for ~7 bucks. Works great in my kettle. I wouldn't try to lift the grain out of there using the bag though.

thanks. i guess there aren't many biab guys around here. maybe i'll take this to the biab brewery website, as i'm really curious if this can handle 30# or so of grain...

I (and the wife) made a BIAB bag a couple weeks ago. I'll try to remember to take a pic tonight. I'd been using the 5 gallon paint strainer bags, but they were just too small and I got poor efficiency. I still use the 1 gallon bags for hop bags, though if I do something with lots of hope (more than about 3 oz) I'll need to use 2 bags, I think.

it'll hold the grains with no problem as long as your stitching is sound. did you use nylon thread? if not then go over it with nylon thread. The hard part will be lifting the grains out. Even that isn't going to be that hard.

I've done BIAB batches with up to 22 lbs of grain 6 gal batch and I lift that out if the keggle with just the bag. Hardest part is fitting the bag through the opening.

My bag is double walled and stitched at the top rather than the bottom.

That said, if you get the real tight weave voile material and you use the right nylon thread and stitch (which from your pic the stitch looks good) then I would be fine with lifting however much you can lift with out worry on the material.

Yes. The reason I bought a steamer basket and recut the top of my keggle was so I could uniformly lift the bag out. I constantly had issues with the bag getting caught/stuck/dragging against my brew pot. Furthermore, it was difficult/irritiating/hot to grab a bag full of 170 degree grain and squeeze/move it.

So I love BIAB because of the simplicty of the system and the time I save- I added a steamer basket to resolve the shapeless bag issue.

Food for thought.

Oh yeah even before the steamer basket, I used a rope and pulley to lift the bag. The rope has loops with a "S" hooks in it and use the "S" hook to link the lifted bag at different heights.

Going back to the shapeless bag issue, lifting 23 pounds of wet hot grains and *holding it* so it can drip into your pot- pain in the ass.

Consider a way to lift and hold the bag so you don't have to.

Doesn't sound like I like BIAB, but I'm loyal. Sparging is so... 20th Century.

Indeed, I am a big fan of the steamer basket approach. It does require an additional purchase and possible modification of the pot for the steamer to fit. Or it could just fit too.

I use a A frame ladder and 2x4 with a hook to let the bag drain.
