I do not. I'm skeptical at its 22 lb max capacity - that's not a lot of wet grain, but maybe it's so good that a couple of batches wouldn't take long?

Thought I’d share a little data on this method, since I have it.

I made a bourbon mash with 17 lbs of grain and 10 gallons of water, which I fermented on the grain. Last Thursday, I strained all of it through my BIAB in a holy bucket, collecting everything in two 6 gallon buckets. While pouring them into the still for stripping today, I decided to weigh them. Net weight of the contents of the buckets was 66.2 lbs. at 8lbs/gallon, that comes out to 8.275 gallons. My measurements aren’t precise enough for me to call that anything better than 8.3.

I have a beer brewing book from the ‘80s which states that you can assume that each pound of grain will absorb 0.1 gallons of water after mashing and lautering. Using that number, 17 lbs would absorb 1.7 gallons. 10-1.7=8.3, which suggests that simply letting everything drain through a BIAB bag and sit for a couple days is a reasonably effective, low effort way to get the good stuff out.

Kinda surprised no one has engineered a press with a cylinder, strainer bag, tire inner tube, air compressor.

Heller.......

Kinda spendy but a pneumatic fruit press would be great at pressing out grain

Heck. I'm positive you could build one for twice the price hahaha

For real

20 gal. Bubble bags work well and are durable. If you're in a large city you can get silkscreen material cheap to filter with.

I know a few wine makers that have this type of press and it's great for grapes on a large scale.

I have a mechanical grape press. I will never use it for bourbon wash after learning how to steam the grain.

Right for the cost of the pneumatic press you could easily get on steam and never have to worry about straining
