Twin condensers , Single boiler ... Possible ?

Postby Wraith71 » Fri May 22, 2026 11:49 am

Ok This is one of those idea's that's been asked to me a few times ...

Is it possible to run twin boka stills off the same boiler .. ? We all know they take forever to run if your using anything bigger than a 25ltr boiler SOOOOOO....

If you have a 65ltr digi boiler and make up a lid that has two 2in holes and add a matching pair of 50mm boka style stills .. would that be effective ??
To my way of thinking its like adding twin exhaust , single boiler with more than enough power to supply vapor ..


I have heard ppl mention this , but NEVER seen anyone actually tackle it. So if any one has tried or can lend some info .. pls let me know.

Yes you theoretically could run two, but I reckon you'd find a problem with a vapour imbalance - that is, the speed of vapour up and liquid down differing meaning your proof and cuts would be a mess.

Not sure if ppl know that a Boka still is just for clean neutral, besides throwing away the first bit ... you don't actually make cuts as there is no flavor.
The condenser keeps a supply of the highest proof running in the column (refluxing) you don't run it down to collect tails, and you collect in smaller portions compared to what's refluxing .

Perhaps you might need to reread the cuts section Wraith.

I think they do unless they've never done any research

Um, completely wrong there bud, you still need to cut Fores/Heads/Hearts and finally Tails and each cut will taste different.

Collecting in small portions is what making cuts is all about, once collected you then blend the cuts
.
And finally, yes you can run a double head but as been said previously they will never be 100% balanced and will therefor mess with the cuts.
.
Now, if all you want is bulk crap grog by all means go ahead but if your after a great clean booze you can be proud of well, just dont

Well thanks to all those that weighed in with any information .. . BUT the question was has anyone actually tried this ?

So far that's a no .. just alot of nay sayers and speculation as to what MAY happen .. Thankfully I'm a bigger person than most and remember this .... 5000 yrs ago in the middle of the desert people built pyramids without computers moving stones over 100tons .. Thomas Edison made a light bulb after trying and failing for yrs ... Sir Edmund Hillary climbed Mt Everest after all the experts told him " you'll die trying , there's NOT enough air! " No I'm not comparing myself to these ppl , BUT I do share their spirit of adventure and ingenuity. I have made spectacular fails and successes , never stopped me from trying ..
I'm not doing this for myself just experimenting for a friend .. they live in a unit , have a full time job plus a 2nd job , plus nosey neighbor's. So space poor , time poor and security issues .
I already have 2 identical boka stills , So this is just an engineering question as to how and if someone's tried what results did they get??

Either way win, lose or draw, I'll be nice enough to post results .

On a personal note .. I haven't made nasty tasting crap since I was 15, that's how I got nic-named Wraith .. A Wraith is an evil spirit ( AKA my earlier clumsy distilling attempts ).
And Ive never done cuts with neutral-vodka , personal choice. I use my grandfather's method , he used it , my dad used it , my brother use's it so do I .. Sorry if that annoys anyone but there's no taste in what i do , the only change is the Alcohol % I run from XX to X then finish. Works for me .

Happy brewing people.

Don't need to actually try it to understand the reason not to do it. Never said it wasn't possible, and by your own descriptions the result will probably suit your taste preferences just fine.

That said, I fear that as someone who says there's no need to cut heads out of a neutral, your findings aren't going to influence much here.

At a home/hobbyist level, I would think not all that economically feasible ... 2xcost of columns, clamps, water lines/connections ...
I think simpler to use a 4" plated column and add an extension with scrubbers
