Hey guys
Once again thank you all for sharing, there is some great info coming through here.
Elricko : I think my packing is the disappointing factor here. As for your question, ,and no offence taken when so ever
, my copper was not all that clean. I find it very hard to get the copper to a "fresh" state. I use vinegar for the initial clean and then boil them in water, though its impossible to get the oxidized/sulfurized blackness out of them, and the smell I get from them is pretty much identical to the aftertaste I"m getting. I hoped that with the intense reflux they give I"ll be able to strip away that after taste, but I guess I needed to fail to find out.
As for how packed my column in with copper, I just recently repacked it with a fresh fill and I have a feeling I rolled up the mesh a little too lose. Even with very careful monitoring I can not seem to get anything over 85% ABV, used to get 94% easy with my old packing. I was trying to research if I can loosen the packing up a little to decrease heating times and increase reflux stabilization times, but I guess there are no two way around it, you want a clean run using copper, you have to pack rather tight.
John & Elricko :
Can you elaborate more of the use of rashing rings? I"ve never used any other packing besides copper, it seems like anything with such a dramatically smaller surface area will not make that good a packer, yet it seems to be. Also John, you put the rings into the actual boiler? Is this to suppress activity in your wart as is boils? Never heard of this practice before!
As for my failed rum, no worries, it will make a perfect maceration agent.
Thanks again!
