Why CCVM?

[Bolverk]

Howdy all,

I see all these CCVM builds and I'm curious what the draw is... you either go from 0 or 50-100% reflux, the dimroth condensers look like a pain in the ass to build, and the whole dropping the coil down into the vapor path seems again like a pain in the ass. I can't think of a single professional distillery running a CCVM. A standard CM with inline dephleg seems so much easier, is adjustable from minimal reflux (id say 0-100 but even an empty dephleg is going to have a little reflux) up to 100%.

What's the draw to these designs? I'm clearly missing something. Please understand, I'm not talking shit, I honestly don't understand why someone would build one.

Best,
