Re: Linear Flavor Theory and Reflux

There is only a linear smear of alcohols because your still, or its management, is not separating the different alcohols by volatility. A fractionating column, run properly, will certainly separate heads, hearts and tails. My still runs for hours at exactly the same temp producing pure flavourless '...

Re: Ideas for inserting packing

Thanks for reply, Bushman. I had another think and have come up with what seems like a simple solution. I used a piece of PVC tubing that fitted the inside diameter of my column and attached a wire to one end. Then I stuffed a scrubber in the top end, shoved a broom handle up the tube and pushed the...

Ideas for inserting packing

About 5 years ago I did the original pack with copper mesh from Amphora but I am now ready to re-pack my 1.1 metre one piece 2" VM column with SS scrubbers. I must have just rammed the wads up last time but I am wondering if someone has a good scheme for getting the scrubbers inserted without severe...

Re: Copper Mesh source

Thanks for the reply, myles. You are echoing my thoughts, now, I must say. My boiler and column are SS. I originally used Amphora copper mesh several years ago and, due to neglect, it is in a pretty sorry state, especially in the lower end. Now I know why the still doesn't perform like it used to! I...

An addition. If you need to kill power, you can put your through tubes at the base of the column. This will control the power without upsetting the reflux action going on in the column.

A good standard strength for many of us is 40%. A store bought gin is about 47%. It's your grog so you decide.

As for the carbon, Grayson has it about right! You will take from that that there is no critical recipe to follow. How about half a cup (or so!) per litre?

I have been down this path so here are a couple of ideas. I used a 1 metre column packed with structured copper. I also separated the water flow so I could independently control the flow to the cooling jacket and the product condenser. I also packed the SS head 'column' with mesh. For controllable r...

Look forward to hearing how it goes. The steam test will help clean it out but don't get worried about how the steam test goes as an alcohol charge behaves very differently.

Good luck.

Just one thing ... The Starting Temperature. I use Still Spirits yeast, and pitch the yeast at approx 24 - 26 deg C. I think the safe starting temperature for the SS yeast is between 20 - 28 degrees C. After starting the yeast, it will ferment at higer temperatures. I'm not familiar with your yeast...

Sure takes a lot of words to explain!! Why does anyone need to know, anyway? What's wrong with having just enough reflux to keep the temp stable?

How about a rule of thumb?
Very little output = lots of reflux.
Lots of output = little reflux.

Sounds pretty much right. One of the purposes of the washer is to ensure that the distillate gets redirected into the centre of the packing. This is critical. Certainly the output slows as the percentage lowers but if you want to keep all tails out you must watch the temp and switch bottles quick! A...

You are building a vapour managed (VM) system which is a good choice. Your reflux condenser HAS to condense ALL vapour so you have the take-off valve in about the right place. And, yes, the vapour will flow out that outlet. I also have a copper 'washer' with 4 points angling down to get reflux into ...

Wot KH said. Especially about a mixture only ever having one BP. Alcohols just don't boil off differentially unfortunately.

Yes, incoloy is very suitable as incoloy was made for aggressive environments. I bought one for my latest still. It was quite expensive but it was worth it in my opinion. It won't corrode like cheaper "normal" elements (at least I hope so!!).
