You'd need really advanced equipment to distill beyond 95%. It'd take a really heavy duty vacuum or a crazy tall reflux column. Actually, I don't think you could do it with a column.

so what you are saying is ...some distilling aperatus will save the pga for the next time to re use ?
depends how much flavor transfers ..you might have to use the same tobacco flavor for the next batch .
and then the reduced part in the boiler is your flavoring ??
Nothing that filtration can't remedy. Are you going to freeze filter the extract to see/gauge how much gunk the Isopropyl Alcohol pulled from the tobacco? My extraction was performed long before learning how to precipitate gunk from an alcohol base, that step might make a difference in overall flavor.
Yes I did filter the Isopropyl, but not the conventional way. Transferred the unfiltered extract out of the crockpot to the freezer and let the residue settle at the bottom for 48 hours. Skimmed off the top, and filtered the result. I feel that is all the filtering we need - let gravity do the rest.
The only trouble was, the heat at 165 degrees produced so many fine particles, that they went right through the 1 micron filter. This had nothing to do with the Isopropyl - same thing happened with the Ethanol. Probably best to reduce the heat to 150 degrees and compensate by increasing the time, and/or pre-soaking.
That makes sense except I am getting a plastic taste from one of my extracts - even though I lined the plastic cap with aluminum foil ... The problem might lie somewhere else though.

Just got back from Hobby Lobby and got everything I needed at half price. Thank you for the tip.
A Drew Estate "Acid Blondie" cigar extracted quite well, even better than the Rocky Patel V.'90 if you like the -unique- flavor produced by the "Acid" tobaccos. I processed it with a 72 hour cold soak prior to performing the 12 hour hot extraction. I then transferred the flavor to PG after a 75% reduction but didn't evaporate all the ethanol from the blend. I'm going to be playing around with variations of this method and see what transpires. Experimentation can be addictive.
Currently in play is an extraction of Cornell & Diehl "Mississippi Mud". 72 hour pre soak at room temperature, an extended 16 hour hot extraction @ a lower 130F followed by a 72 hour room temperature soak. I bet this pulls some oil...
Most of mine are pretty clear after mixing, translucent.
Most of my extracts lose their cloudiness after the final filtering, a few however do remain cloudy like the recent "Acid Blondie" cigar extract.
after 85% reduction i didn't filter, but despite that, the extract itself is very dark, but crystal clear when i look at it in the light. used about 7% NET (about 2ml) per 30ml. just missing about 5ml of PG nicotine i haven't added.
this is what the eqluid looks like after adding the extract
doesn't look very tasty, but probably won't effect the flavor, just found it a bit odd looking..

That -is- cloudy, I've never had a mixed NET look that way. What tobacco did you extract? Check it again after a day or two and see if it clarifies any, be sure to post your observations, I'm curious!

Nice to see, that you are experimenting again. Very interesting.
I have darker tobaccos to extract, latakia, fire cured kentucky, london pine ect. I want them strong !
I have soaked them for a day in ethanol and at the moment i have began the hot ethanol extraction at 160°F for 14 hours. The glasses and the ethanol are cold, therefore 2 extra hours. After this i will let them in my sous vide at 113°F for 9-10 hours. After this i will steep them at room temperature for one or two days before taking out the tobacco, filtering and freezing. I am thinking that a longer steeping time with the tobacco could be bring a stronger and fuller flavour like you have proposed for cigar extraction.
The acid blonde is interesting. I will buy one. Do you have more good proposals for cigar typs ? It would be super to know what cigar is the best for extraction. Have you tried many different cigars and have a litte experience referring the typs ?

I have had the exact same cloudiness with my last 4 or 5 extractions. And it doesn't matter which tobacco I use - Nightcap, Louisiana Red, Virginia Flue cured - or which alcohol - Ethanol or Isopropyl ... I initially thought the curl-pit was too much heat, or too long a soak, or perhaps the ISO, but none of that was the cause.
My Problem turned out to be this 1 micron felt filter from amazon !!!
Singed Polyester Felt Filter Media Fabric Sheet 1 Micron: Industrial Process Filter Bags: Amazon.com: Industrial & Scientific
The 1 micron rating is nominal; effective is supposedly 2.5 micron.
I decided to run the cloudy extract through a coffee filter, and it came out crystal clear.
The only conclusion I can draw is that this filter does not even compete with a coffee filter. Hope this will help someone.
P.S. The cloudiness however did not affect the taste. My extracts all taste great.

I am thinking that the clouds are normal because its a very fresh mix. After a few days it will be more clear. If i have seen this at my fresh mixtures i thought it could be only air because i have shaked them.
I see no bubbles in those two pictures. In my particular case, the cloudiness does not go away with time.
I've only extracted a dozen or so cigars, they're not my area of expertise. The Rocky Patel "Vintage '90" and Drew Estate "Acid Blondie" are the only cigars I've extracted that I like and both were recommendations from other extractors. Other cigars suggested by patioclark are the Rocky Patel 2008 Autumn Reserve (in the lighter wrapper), and the Perdomo Lot 23 (not Maduro), I'll be trying those next.
Let us know how this turns out, sounds interesting.
Be sure to freeze filter this one adequately because you're likely going to pull a lot of oil with this extraction.
Okay, i will filter it first with a coffee filter and after the freezing with a 2-3 mycrometer paper filter. I am very excited if it will be stronger with the longer heating and steeping.
I noticed the same cloudyness from the filter. For the benefit of those reading this. This filter is the exact same as exchaner is using. We split the cost and he mailed half to me.
Now I suspect it's the loose filter fiber materal contained within the filter itself doing this. What I purpose is maybe boiling the filter first then giving it a good rinse then let it completely dry before use. then try it again.
I myself have stopped using the filter as I find I need to use to large of a piece for it to be effective in the funnel I use and this soaks up more then its worth. Also the prep time involved every time I need to use this filter is a bit more then a care to spent (Cutting, boiling, rinsing and drying). Call me lazy but I like the idea of use once then toss it out as with coffee filters. I find I get good enough results with a hot filtering using coffee filters and cold skim. I think this 1 micron filter would be good in a smaller size used in a Borosilicte forced vacuum type of setup but for me it's just over kill.
