What's wrong with using a 15" hinged false bottom in a keggle and leaving it there during the boil, besides being an overpriced cake rack? Would all the cold break and pellet hops settle below it when I use an immersion chiller?

I have a 12" opening on my keggle, inside diameter is 16". What are you using to keep your bag from melting?

Nothing wrong with it at all...

I used a steamer insert and now use a stainless BBQ grill for a false bottom. Both of which are in during the entire boil.

It will work - just make sure that you have enough support to handle the weight of the grain. My first attempt with about 34lbs of grain on a hinged Keggle FB caused it to sag in the middle. It was not a pretty situation but I was able to get the bag & grains out and into the BK to finish the mash. Solution was to install a few SS bolts along the inner edges at the center of the FB, acting as extra feet.

I always just pinned my bag to the top of the keggle so it could never touch the bottom but a false bottom is probably a much better way to go.

Are you using a keggle? Is it a round grate? The issue I see is to cover the whole bottom with a rack or grate, while my opening is only 12".

I got the hinged 15" false bottom from Jaybird on here and it's maybe the best brewery purchase I've made. I just tried out my first BIAB with it and had no scorching problems while direct firing it on my propane burner. I was recirculating with a pump, but I honestly don't know if that's necessary if you're gentle with the heat and stir while the burner is on.

Do you have a center dip tube or a side/whirlpool tube? Did you keep it in during the boiling? Did you chill in your keggle on your first BIAB? Would you say the cold break and pellet hops stayed above or below the false bottom? Thanks...

A beer club buddy is coming over tomorrow to help me establish a rigging system with pulleys and a cleat. Hopefully it will be easy to use. I feel another picture coming on...

It's pretty hard lifting it this way;

I do have a center dip tube and left both it and the false bottom in during the boil (although they are pretty easy to remove and clean afterwards). I have a big immersion chiller with a recirc arm that I dropped into the keggle after the boil. Regarding cold break, hop particles, and general clarity, I think it's a tradeoff I'll have to make for the convenience of this method. I used whole hops and squeezed the bag pretty good after the mash. I think the whole leaves probably acted as a decent enough filter bed, but it seemed pretty murky when I pumped to the carboy. I would imagine that had I used hop pellets, a lot of them would make it through to the fermenter, but I can't confirm. I know a guy who's been doing BIAB like this for awhile and have sampled some of his light pilsners that were delicious, but cloudy.
