Hey everyone. I haven't been on the site in a while good to be back.
Im building a ss pot still with thumper and shotgun condenser.
15.5 keg boiler 7gal keg thumper. 2" tower 11/2" after 180 into thumper
11/2"out of thumper 1" after turn at slant into shotgun.
My question is should i put packing scubbies ect in the boiler tower?

My personal recommendation would be no packing, for two reasons. First, a properly run pot still can give excellent results, and packing will only reduce flavor. Second, if you ran slowly enough to get real concentration stacking in the packing without a reflux condenser, you'll just have a very slow pot still.

Some will speak of the need to have some reflux to get great spirits, but I've not found that to be the case (and neither have the Scots, or the Irish, or some of the best bourbon makers).

What prompted the question ? Why would you put scrubbers into a pot still?? I agree with ZB, you aren't condensing at the packing, so it will just heat up to a point where it does nothing, and slow down the process...

I have 1 copper scrubber (a big one) at the base of the riser in my pot still. I do this because I do not have copper anywhere else in the vapour path on any still configuration I have. I figure it is best to try and round up any sulfites at the stripping stage - I could be convinced otherwise....

There's a bit of "passive" reflux going on with an uninsulated pot still if the amount of condensate collected in my offset carter head is anything to go by.

I agree with Kimbo. The general consensus seems to be to have some copper in the vapor path to help strip sulfites(?). I don't always put all my trust in consensus, but this is an innocuous enough concept to accept until I might prove to myself otherwise.

I don't think the OP was suggesting he was looking for reflux (could be wrong), but maybe just to introduce some copper into the vapor path. In that case, I would suggest a small amount of loosely placed pure copper scrubbies. Not so much that you overly restrict the vapor flow.

I apologize for an overly narrow interpretation of the question. Since all my still heads have always been all copper, I assumed the scrubbies were for reflux.

I also assumed reflux rather than sulphide removal.
I have a site tower that I have on occasion plumbed into both my boka and my pot still.
The reflux from the boka makes it look like it's raining...heavy.
The pot still generated a heat spot at the scrubber, vapour passed through and at least the wAy I had it set up - saw nothing...
