Stripped low wines diluted to approx 20-30%. Packing height 900mm, diameter 50mm. Was going to increase packing height to 1.4m soon as I get the column welded.

I have now build a 4" x 61" (room for 60" of packing) column :D
it holds 40 pounds (18.18kg) of 14mm marbles and has a total weight of 55 pounds (25kg).
i made a copper plate for a piece of type L pipe that sits on top of the ferrule, trimmed two sides so it can be removed if i ever want to take it out. I got the idea from Bobbywolf :wave:

Well I’m getting prepared to do an experiment with marbles.
I will be testing the effects of: different size marbles, at different to power inputs, to column sizes.
I currently have 14mm marbles from hobby lobby and am looking for places online to buy other sizes (online would be the best as long as they ship to the United States or Canada)
I can’t seem to find anything other than ~14mm at any store I have gone to.
Any links to online stores would be great
thanks

well i have not even had a chance to think about doing test with marbles. i am now home for a day after being gone for 8 days and have a shit ton of birdwatchers to run (150l of wash to strip ~3 stripping runs as well as 70l of low wines). started well, cold column at the start ups the abv to 90% and then quickly drops to normal.

started my spirit run ~52l 40%abv i have my 2" ccvm head on my 4" column, turns out it cant put in into full reflux at full power :thumbdown:
after a few failed attempts on fixing it i took a copper disk with random holes in it,that was in my scrap box and used it to block part of my take off in the tee.
i then used my notes from when i ran the 2" to scale my take off rate to the higher power input. this should give me a fairly similar reflux ratio.
my 2" would give me 96.5abv my 4" with the same marbles and 12" longer column gave me 94-95%abv :think:

i think this is because the reaction between the vapour and reflux is not as violent do to the fact i have not scaled my power input to my increased column size.

I've always used marbles for packing. Perfectly happy with them.

I have one 6 gallon still which I packed with copper mesh. It actually puts out too high a proof for my taste, since I like to make whiskies.

Same here,
I ran with 4 sizes of marbles
I ran with scrubbies, with copper mesh and with SS mesh

in a 3" x36" ccvm column
Marbles drop my ABV% by about 7% and will not tweak with adjustments to power nor TO ratios. Sits there at 85% from start to finish.
My marbles are 14mm. Thats optimum. Smaller marbles ABV drops and just floods so power reduced. Larger diameter, ABV drops and the RC needs turned up, and power reduced.

Scrubbies do work better if more tightly packed, or rolled mesh is best if I want to get above 92%

I know Odin claims a great whiskey at 96% but as UJ says anything that pure does indeed taste different, good for vodka and gin but distinctly lighter, too thin for my whiskey or rum.

In fact since I strip run all my beers I get a better whiskey by potstilling the low wines back with each stripping run and keeping the tight hearts. I am increasingly using reflux to blend with the potstill spirits. Mature each of the hearts separately before blending.

I make a drop of brandy made from red wine and I am happy with what I get

with the marbles my purity is down a little , but when I dilute to 40% which is what I want for my brandy I am not sure if my yield of 40% is that much different

I normally add some caramel to colour , a handful of raisins and some wood chips and let it sit for about 6 months ,

by that time I do not know how much I have got :D , I find with the marbles my spirit is cleaner

I suppose my question is although you are down 7% on what the amount of distillate you get are you that much down on what you drink

I am down 7% Alcohol By Volume, not a lower yield by volume. I should have written 7%ABV

I understood that you spirit was down in strenght

my question was are you down in final volume after cutting to 40 %

that is , say , you were getting 10 litres @ 80 %

are you now getting 10 litres @ 73 %

or approx 11 litres @ 73% which will give you the same volume @ 40 % , cut
