im 2 hrs in the heating process. ive been using chopsticks to give it a stir and shake the tobacco up a bit. not sure how it will effect the final result as this is my first ethanol extract. the extract is looking pretty dark already so im not sure if ive messed up the process in any way. have my fingers crossed that its going to turn out awesome.

hi ppl. new to this forum. basically joined so i could get in on this thread. ive been a long time lurker of the n.e.t. section.
im currently doing the heated ethanol extration method and can i ask when heating it will the water evaporating get into the extract if i leave my cap too loose? ive been seeing some condesation on the cap
If it beads on the crock pot lid, it could. Try covering with a towel instead.

Welcome to ECF and the extraction sub forum. :) Screw the cap down lightly but don't over tighten, no water vapor will get in but excess pressure can still escape. One of the many reasons I use canning jars, their lid/ring are ideal for this. Ethanol will readily absorb moisture so keep the extraction container sealed while in the hot water bath (crock pot). I wouldn't physically stir the extract, it really doesn't need any help during the process but if you prefer to do so anyway (sometimes I can't resist), just gently swirl the contents inside the sealed container. Don't be alarmed if the ethanol begins to simmer, it just means you're near its boiling point and that's the temperature I feel produces the best results.

Dunhill "Nightcap" does yield a flavorful, robust extract. If you enjoy it you might also like Cornell & Diehl "Mississippi Mud". Have fun and be sure to post your observations/questions.

ive stirred it a few times, making the extract really dark looking like a vg extract. i still hope its salvageable tho. instead of a crockpot ive been using a baby bottle warmer set at around 65-70c. i may be wrong but i thought ethanol is only hygroscopic in percentages higher than 95% but i still kept the cap on anyway. saw bunnykillers pic in the other post and i must say rite now my extract is looking darker than her vg extract.

I wouldn't worry about the color so much. At this point, what matters is pulling flavor out of that leaf. You'll clean it up in filtration and freezing. All that the dark extract means is that you might have to work a little harder on that end.

I'm not a stirrer, but I do a lot of shaking. ;)

Nightcap produces a very dark colored extract that's nearly opaque, it's just the tobacco. Different tobaccos yield extract of different color and clarity, some produce a light golden tan color that is highly translucent while others produce a reddish hue but many tobacco blends yield a dark brown to nearly black colored extract that is nearly opaque until mixed. The extraction method one uses also influences color. A cold ethanol extraction yields a very light color depth when compared with a heated ethanol extraction of the same tobacco which will be darker.

I've only ever used dry ice to shrink machined metal components to ease fitting a close tolerance (tight), assembly. Worked very well for that. It's extremely cold at something like -100F and works/keeps well inside an inexpensive insulated ice chest. Don't really know if it would stay around long enough for our purposes though, it takes time for things to precipitate out of an extract. If you try it be sure and post the results. :)

Looking forward to your observations. Love the outside-the-box thinking.

I probably will try it with dry ice sometime next month if any one of the four extracts I am currently steeping turn out OK. Will post the results, including my observations on the four extracts - all dry leaves, including Big Spirit.

BTW, I have tried Big Spirit from NET.com, and despite what they claim, tobacco is not the only ingredient. I taste traces of chocolate, nuts and mocha ... Anyone with the similar observations?

Just tried American Spirit extraction after a two week steep, and it came out amazingly well - just like the real thing, a nutty-sweetish tobacco. I did use a high % though - the equivalent of 5% of the 75% reduction. Still have three more extractions steeping. Altogether very very happy with how the extraction came out.

im back with results. finally had it filtered and mixed it to 5 and 10 %. i must say im pretty impressed at how much less gunk buildup there is compared to vg/pg extraction methods. Im now trying to figure out the best way to reduce down my extract. 5% was a little too weak for my taste. 10% was closer to where i like it but the alcohol was too much for my liking. hoping that reducing it would help. Dunhill nightcap taste great.. some nice smoky goodness!! im now a convert to the school of heated ethanol.

Thanks for sharing the method str8

reducing the extract further is possible when one uses PGA... I use a crockpot, stainless steel bowl and the warm setting. Float the bowl in the crockpot, place extract in bowl and put on low heat ( warm setting) and let the PGA evaporate off, be mindful and dont let it evap off completely or else you will end up with a thick gooey blob in the bottom of the bowl... I prefer to add about a teaspoon of VG to the extract as it gets near the "thick" stage of evap. to keep it from going into the blob condition :)

Hi everyone,
I was wondering if the sugar content of dry leaves can be reduced somewhat by soaking them in warm (or boiling) water for 15 minutes or so. I tried this method in my smoking days without any loss of flavor. Can't remember however if it did anything to dissolve the sugars. I know this will not work with flavor infused tobaccos, but what about straight tobacco leaves like Big Spirit for example?
