Tobacco extraction using heated Ethanol

[l337acc]

I might also add that so far I've only liked around 5% of the different tobaccos/blends I've extracted. The rest of them ranged from blah to just OK, at least for my taste.

Well then in that case, even though taste is subjective if you've already done most of the work I think I'll consult your other thread and start with that, maybe even try the 1Q again and pick out most of the Virginia .

Another way to use VA might be to add just 2% to another flavor as an enhancement.

Indeed I'll be trying this. I think my mistake was using too much VA in all the extracts I've tried. I remember extracting ONLY the Dominican Cigar Filler and it tasted just like having a cigar in your mouth, but after 1ml the flavor got muted because of the gunk. I'll give it a go again with some Dark Air Cured given the new filtration techniques.

Today i have tried a another method. I have put ca. 8g tobacco with 70ml Ethanol and 70ml base (VG/PG/nicotine) in a jar. I will heat it at 50°C for 4 days. After this i will evaporate the ethanol and filter it.

The idea is not to make an extract and after this a juice. I will make a ready juice. Perhaps if i have luck, the flavour could be a little bit deeper and i could reduce the steeping time. The problem is, that i cant do the freeze filtering because it works only in ethanol.

Are there any coagulants which could help to reduce sugars ?

Let us know how it turns out. Sorry but I haven't a clue on how to safely remove any extracted sugars.

My latest experiments are ethanol based using lower heat for much longer durations followed by short room temperature soaks. I've got another idea I want to play with but will wait for winter to do so. I want to find a way to gently circulate hot ethanol through the tobacco during the extraction process.

If you can find someone with similar taste preferences you could then try their other "favorite" tobaccos. Hopefully I'll have some new cigar recommendations in a month or two, cigars are my current focus.

Good to see you back Str8. This thread slowed down to a nearly halt during your absence.

I've been busy working on my house and property, rainy days (like today) allow time for extracurricular activities.

Not wanting to rule this extract out completely, I decided to make a hybrid. I had some flavors from TPA lying around and I just made a 30ml bottle. The mixture was thus:

15% flavor
14mg nic
60/40 pg/vg

1Q - 50%
Turkish Tobacco (TPA) - 40%
Smooth (TPA) - 5%
Black Cherry (TPA) - 5%

The result is surprisingly pleasant for something I just slapped together. Might have used too much Turkish, but overall it's like a spicy Virginia with black cherry undertones. Right on.

If I were to try it again (which I will), I would definitely not use as much Turkish - in fact I would probably replace it with something else entirely. The thing that stands out the most is that the "funkiness" of the Virginia has been toned down drastically by adding other flavors.

All I vape is "flavored" (hybrid) NETs with tobacco extract being the lead flavor. Vanilla tobacco, caramel tobacco, Vanilla, caramel, hazelnut tobacco, Peach tobacco, blueberry tobacco and many, many others. Not all concentrated flavorings play well in a NET, the balance is very delicate and the natural tobacco flavor is surprisingly fragile.

Ready. The idea to do this was to make a ready net and not an extract to reduce the steeping time and to avoid the step of mixing the extract with pg and vg. The result was a dark extract mixed with vg, pg and nicotine and not a ready to vape juice.

After evaporating the ethanol I have got a very dark mixture and not a bright brown ready to vape juice. I had to mix it with more vg and pg to get a usually colour for the ready juice. It was to much tobacco for a juice. I estimate that the right amount must be 2-3g tobacco with 70ml PG/VG/and nicotine for a ready to vape juice. The taste is good but i have to wait 2-3 weeks. The good result from this little test was that you need a less amount of tobacco as by the usually hot ethanol extraction. I think you are saving a bigger amount of flavours, because the pg and the vg have been in the jar during the whole extraction and not only after the end referring to the only hot ethanol extraction. This is really an advantage. A problem of this method is the time of filtering because of the vg and pg in the mixture. Its not funny with a 2,5 mycrometer filter paper.

Usually all my hot ethanol nets referring to your old tutorial are changing complete in taste after 2-3 weeks. They become all a very big smokiness taste, a little bit similar to a real cigarette. Its a big difference referring to an only hot pg extraction. My nets which are made only with hot pg have nothing of this kind of smokiness. Hot PG extractions without ethanol are lifeless.

Hey hey, its my idea !

Franz von Soxhlet - Wikipedia, the free encyclopedia

I want to buy a soxhlet with a drain cook and cooler with a drain cook for separating ethanol. Dont know if the separating over the drain cooks will work. Its excactly what you want. Another advantage is to make the extraction at low temperatures in the soxhlet because of the cooler which cools down the ethanol before it gets into the tobacco again and again and again. Its cool.

I am waiting till weeks for an offer of two different vendors. The first want to have 600 Euro but cant make a drain cook at the cooler. Hope the second vendor can make a better offer.

Wow, after mixing the extract to more base it was awesome good. The flavour is deeper as my extractions with only hot ethanol and there was no steeping needed. At the moment i am tryiing the same method with 2-3g tobacco.

 

[jonnydoe]

I have no weighing scale and i think i have done it with perhaps 4g. It was to much for a ready to vape juice with 70ml base and 70ml ethanol. Next time i have to try 1-2g only. But i hate the filtering through my 2,5 my paper filters. I have been waiting for 6 days because of the vg and the pg.

Do someone have a idea for faster filtering ìn the same quality ?

 

[Exchaner]

Have you tried putting your filter inside a large syring and gently pushing the liquid through? Also better if you filter the liquid with alcohol still inside.

 

[jonnydoe]

What kind of filters can i put in a syring ? I have big round paper filters. I will try it..

Some people use cotton, but it is not as fine as 2.5 micron. What I'd do is trace the outside diameter of the syringe onto the filter paper and cut to size. Two layers of filter inside the syringe should do. You can also use a squeezable plastic bottle that has a nozzle. See next post.

Interesting, must try...thx

I use that for my alcohol extractions. It may also work with your mixture of Pg&Alcohol. Vg might be a bit more difficult. You may want to leave it out until after filtering is done.

I'm at the last step (PGA reduction) in my first hot ethanol extraction attempt and it's taking way longer than expected. First, let me mention what I've done so far.

I ground up an old cigar from my humidor. It was pretty dry so I was able to just use my fingers. It was about 16g and pretty much filled my 8oz mason jar. I then filled that with 190 proof Everclear, put some cling wrap over the jar top and set the lid on loosely. I heated that in my Crock Pot half filled with water for 12 hours on the warm setting. My laser temperature gun showed that to be around 160 F. I let that cool a little bit and filtered it through a #4 coffee filter into a fresh 8oz jar and gave the filter a good squeeze to get all the juice out. I put that in the freezer for about 40 hours. It was roughly 12 F (above zero). I filtered that again through the coffee filter but didn't pour in the last little bit that had the congealed oils. I then filtered again with 2.5 micron lab paper filter. I now had about 69g of filtered PGA juice, filling about half the 8oz jar.

So now I'm trying to reduce the PGA through heated evaporation in the oven, in the same wide-mouth 8oz jar (inside diameter about 2.25"), where I expected to get an 75% to 80% reduction fairly quickly. I've managed to keep the temperature in the 140 to 150 F range but now after a full 7 hours, there's only been about a 33% reduction. How long should this take?

Is the weather humid in your location? 7 hours in the oven seems a bit too long - especially if you used 195 proof. I usually use a small shallow bowl with a wide mouth for evaporation.

Yup.....and I just set that bowl in a closed cabinet. Within 48 to 72 hrs of open air evap., the mix is usually down to 25% of the original amount.
