False bottom, manifold, s/s tube... What about s/s ball bearings?

This is splendid. putting the rocks/ bearings in a bag would keep you from stirring them into the grain. just a thought. kudos.

Very good idea.. Worth trying!!

ha! no worries there.. I will def be trying it... The MLT I am planning on using is the 52qt cooler... I've only seen manifolds and tubes...

Exactly! worst case I prove myself wrong... Wasn't it Edison who said he found over a 1,000 ways not to make a light bulb?

National Treasure is an awesome movie. Haha. I like the idea of the ss beads. Wouldn't be that bad of clean up if you had a sluice box lol.

I think that the beach or river pebbles would have zero effects on the mash...they have been underwater for thousands of years, so I'd assume they are pretty neutral by now. I think it would be cool to get some from local river/beach or from your travels and use those.

As far as uniformity, as long as the outlet is covered it should be fine. Figuring out the best diameter range of stone would be trial & error though.

Idk. Rock is Rock. It's made up of many different types minerals, ores, and Dino ****. Look at lime stone which comes from shells and sea organisms. Limestone I believe Is used in the food industry in different ways for its effects on acids.

Rocks in rivers and oceans don't get neutral they keep giving water their minerals (its where water gets them)

I see rocks all the time that have bits of iron in them bc there's rust veins in the rock. Imagine mixing your mash with rusty stones...

So if you're going to use rocks I would def. talk to a geologist or mineralogist.

How was your mash efficiency?

low... close to 70%.. But being such a Frankenstein of a MLT, completely made it up on the spot by using my Jockey Box, I didn't have high expectations nor really was intending on testing the efficiency of the process. It was more conceptual / trial on the use of rocks as a false bottom..

I will say the temp didn't drop, within the 60 minutes I mashed, 2 degrees with no external wrapping of insulation, etc... I was pretty shocked at that...
