So in addition to Louisiana Red, what other tobaccos are you planning to extract? :)
Just the one for right now! I tried different ones and that's the one I settled on. Maybe I will branch out once I complete my 1st batch.
I did buy 3 tins of tobacco, so I don't know how long that will last.

3 tins worth (4.5 ounces) could produce enough extract to flavor between 3 and 4 liters of NET. Something tells me that might hold you for awhile. :)

Louisiana Red is also available in bulk (by the ounce) at a significantly reduced cost per ounce (40% cheaper than the tin price). This becomes important when sampling a variety of new tobaccos because you can buy a single ounce of each for around $3.50 -if- the tobacco you want is available in bulk, not all tobacco is.

They were out of stock so I didn't know.
I really didn't know how many oz of tobacco should fill the jar.
So do I need to put the tobacco in a bowl and fluff it?

Pint jars work great, they can handle larger amounts of tobacco.

Nope, most tobacco is good to go as-is. The only tobaccos I've ever needed to "fluff" are the ones that have been pressed into a hard "cake" or strips and cigars that I've sliced up. Louisiana Red (and most pipe tobacco) is already fluffy enough.


....I really didn't know how many oz of tobacco should fill the jar.....

About 1 ounce for a pint jar, you don't want to fill the jar full of tobacco.

Finger feed the tobacco into a pint jar until it reaches the 10oz mark but don't pack it down, leave it loose. Now add ethanol until it just covers the tobacco (which will pack down a little), then add 25% more which should be somewhere near the 12oz mark on the jar. This usually requires around 300ml (10 ounces) of ethanol. Install lid and lid ring. When you're ready to put it in a hot water bath, loosen the ring off then re-tighten it until it just starts to bind the lid down but no tighter (exactly like when canning food). Then you're ready to go!

Time sure does fly! It's been two and a half years since this thread started and I thought it was time to update the method of extraction to include changes/tweaks made along the way. There are many different ways/variations to accomplish each step of this process but I won't attempt to address them all in this post. Here's the "basic" updated process;

Prepare a hot bath with water temperature set between 160F and 165F. Ethanol boils at 173F so try to keep the temperature below the boiling point.

Place shredded tobacco in a glass canning jar, pour in enough ethanol to completely cover the tobacco then add about 25% more. Lightly seal the jar (not too tight) and place it in the hot water bath, add enough warm water to the bath to match the level of ethanol inside the jar. Once the water temperature returns to 160F, process for 12 hours. Check periodically and add water to the bath as needed. After 12 hours have elapsed turn the heat off and let everything cool to room temperature. (NOTE: For an even deeper flavor extraction, seal the jar tightly and let it sit at room temperature for a few weeks before proceeding to the next step.)

Put a coffee filter inside a funnel and place the funnel in a clean glass jar. Pour the ethanol (now an extract) into the filter and wait for it to flow through before dumping the tobacco in. Once the tobacco has been dumped in carefully begin gathering/folding the edges of the coffee filter together to encapsulate the tobacco inside. In the palm of your hand, gently squeeze the encapsulated tobacco to release/recover as much extract as possible, slowly increase the squeezing pressure being careful not to rupture the filter. Discard the tobacco and filter. Seal the jar and place it in a freezer for 48 hours. Ethanol won't freeze, it just gets cold. While in the freezer some of the undesirable elements pulled from the tobacco during the extraction process will precipitate out of solution and coalesce in the bottom of the jar.

Put a coffee filter inside a funnel and place the funnel in a clean glass jar. Place this "filtering setup" in the freezer and allow it to get cold. Retrieve the extract from the freezer and carefully pour it into the coffee filter, if possible allow the filtering to take place inside the freezer so everything stays cold. Once the extract has filtered through, discard the coffee filter. Allow the extract to warm to room temperature but leave the lid off the jar this time. Reduce the extract by around 70%. (NOTE: setting the open jar in front of a small fan will help speed evaporation.) Once reduced your extract can be filtered to whatever level you prefer, I recommend 3 micron filtration or better.

Mix the reduced extract at 7% to 12% strength. After mixing, allow time for the ethanol to evaporate from your mixed NET. Now you're ready to sample it, but remember that properly aging a mixed NET always improves its flavor. Enjoy!
Thank you for the updated "reader's digest" version of the procedure it really is of immense help. My one question is what type of ethanol are you using. Would Everclear (75% or 151 proof I think)work?
Whitout meaning to sound dense, the 7% to 12% solution is in the PG/VG base? Is this the concentration you'd vape?
Thank you for all the help.

...My one question is what type of ethanol are you using. Would Everclear (75% or 151 proof I think)work?...

I use 190 proof PGA which is 95%+ ethanol and 5% water. 151 proof would work but once you reduced it you'd be left with a water based extract. (Ethanol is considerably more volatile than water, it's the first to evaporate.) You can't store a water based extract long term (stuff will grow in it) so you'd need to mix it all into ready to vape NET. Since PG and VG are both hygroscopic (readily absorbs and retains moisture) the mixed NET would have a 7% to 12% water content that can't be easily removed.

If I were going to use 151 proof PGA, I'd reduce the extract by at least 80% before mixing it into ready to vape NET in order to reduce the amount of water in the finished mix. (A higher level of reduction would further concentrate the flavor strength of the extract, requiring a lower percentage of extract be used to flavor the mixed NET)


...Whitout meaning to sound dense, the 7% to 12% solution is in the PG/VG base? Is this the concentration you'd vape?...

In other words for 100mls of ready to vape NET, 7mls to 12mls of it would be extract (7% to 12% of the total volume). The rest of course is PG/VG and liquid nic.

My last mix was for C&D's "Bow Legged Bear" (a robust flavored extract) that I mixed at 8% flavor strength. For 100mls of ready to vape NET I mixed;
  • 8ml - 100mg VG Liquid nic
  • 8ml - Bow Legged Bear extract
  • 58ml - VG
  • 26ml - PG
After mixing I allowed the NET to sit "open air" for two days in order to drive off some of the ethanol.

Well, now that you opened this can of worms, where do you get 95% (190 proof) ethyl alcohol from?

190 proof Everclear also known as PGA (Pure Grain Alcohol) is available at local liquor stores. I'm fortunate enough to live in an area where it's legal, available and only moderately taxed.

It seems it is available at local liquor stores....but not in California. Our idiotic state legislature is "protecting" us from ourselves, we can only get the Everclear 151...woopee!
