Just an update on this for those that are interested.

Gave the BBMB its maiden run today. Ran some cleaning feints with some old herbs thrown in through it just to see how it performed and check that there was no scorching. It's a winner!

Scythe, you were right. Not too much evaporation from the outer boiler at all and the outer boiler didn't hit a rolling boil until the end of the run and the product was well into tails and coming off too slow to bother continuing.

I am going to need to figure out a way to anchor the inner boiler as it becomes slightly buoyant once the level drops low enough.

Very happy with how this turned out and am looking forward to the first absinthe run.

Cheers,
Prof. Green.

The pot your heating the water in does not need to be food grade because it does not come in contact with the wash could use steel or aluminium

There is probably a more elegant solution but until it presents it's self a few bricks sitting on the lid should do it. :cool:

Nice build prof :handgestures-thumbupleft:
I've got a little 5lt alembic pot earmarked for something like this.

I switched to a pressurised jacketed bain marire about 6 months ago. I don't bother using any form of antifoam anymore, even on my molasses runs. Pretty much fill my boiler within 2 inches from the top too:)

You could try not filling the jacket (outer pot) full. Just enough to cover the element and then some for any evaporation/loss. Steam is hotter than the water itself. This is how I run mine, this being said mine is designed to operate pressurised up to 15 PSI.

Thanks chaps.

I had thought of a couple of bricks as an interim solution res. :handgestures-thumbupleft:

Very true. I used a stainless one as I though it could double as an urn should the need arise.

That's what I'm ultimately aiming for in the future. This little baby is just for experimentation.

Thanks for the link too, I'll have a look at that later.
