Pro-caps? Worth their weight?

These are boilers with half columns, bubble, sieve or any other plates. These stills may make a particular type of spirits. Please feel free to discuss the benefits and features of these beautiful machines and their inventive builders.

Well some of the liquid would go down the nearest dc (being the cap if it's a procap) and some would spread out on the plate and go down other dc's.

The standard caps (depending on plate size have more than one DC) some of the liquid comes from the far side of the plate and some comes straight from the caps next to the DC's.

So not quite as cut and dried as you make it sound, although what you are saying is in essence true as i understand it. :)

Well I didn't invent tray hydraulics. But I can say that every drop of liquid must enter the deck on one side and every drop leaves the deck on the opposite far side. In between entering and leaving, that liquid has to run the gauntlet of the gas dispersers (injectors) mounted between the enter/exit points.

I can guarantee that the procaps work a charm in my Crystal Dragon ACE...

Harry can you discuss the flavor attributes and mechenics of a typical plated system with reguard to the ester formulation compared to say the mechenics of simple pot stilling please?

It's very simple. Potstills contact ethanol/heat/acids to make esters in one place...the boiler.
Trayed stills contact exactly the same, but at every tray. A trayed column is essentially a stack of many pot boilers. Multiple distillations in one pass. Like a series of thumpers.

EDIT: By the way, the Ming link I was meaning above (tray liquid) is here...

I wasn't quite expexting that generic answer.

There is something counter intuitive here with regard what is and is not capable of making a full flavored, smooth product.
I am not refering to what is theoretically optimal.
I am talking about running say for instance,,,, a single run, two plated system (with ProCaps) with a 10 % kettle charge vs a strip (10%) and spirit run with a simple pot still.

"generic answer" it may seem. Nonetheless them's the facts. Simply put, the more contact, then the more esters are created. More esters = more flavours.
How you arrive at that point is up to you...your choice of equipment, design choices, costs etc etc ad infinitum.

But maximum esterification begets full flavoured brown products. That's bottom line. Most hobbyists of distillers who've been around in the game a while will relate readily to the differences / comparisons in products from the various still / distillation types and regimen. WMD's (weapons of mass distillation) must fit the intended outcome.

I am currently building a 2.1/2” column with my version of single pro-cap bubblers.

Having read the comments with regard to contact time I am thinking about adding a weir to the bubbler that would guarantee that all the distillate passed all the slots.



Harry points out the benefits of contact time for flavored drinks but are there any negative issues for neutral / vodka types?
