You said “high”190 proof ethanol and cannabis oils are miscible. This means they’ll mix in any ratio. No saturation phenomenon.
in terms of extracting kief, my advice is to extract with small portions of alcohol; this maximizes recovery. Then, if needed, evaporate some alcohol to arrive at high recovery and high concentration.
One issue is that the alcohol extract won’t be decarbed. Only good way is to cook off the alcohol and allow the extract some time at 110 degrees C.You said “high”

No. All ratios, but very concentrated solutions are syrupy.I'm decarbing the kief before adding it to the alcohol. Currently it takes 0.3ml of the solution to get me high. I'd like to get that down to 1 drop (1/20 of a ml).
So I can add another 100g or so of kief to my current solution?
There must be some point where the alcohol is totally saturated, no?

You can add more kief. Be sure to wash the kief solids with another portion of alcohol. You can set that aside to evaporate.
In fact, if you evaporate your solution down to constant weight, you have pure extract. You can then dissolve that in an arbitrarily small amount of alcohol. That way you can determine and control the percentage (weight/volume) of your tincture.
There is a tradeoff: less viscous (concentrated) solutions absorb better. It also helps a whole lot if you chase your dose with a fatty snack. I use a scrambled egg or two practically floating in butter.
If you use enough alcohol, the extraction is done in seconds. If you can rig a columnar filter, run pure alcohol in from above and watch ‘til the brown color switches to clear or a pale yellow-green.My plan is to continue to add kief from every grow. Letting it dissolve for a few days, strain through a coffee filter and then wait till the next grow where I'll go through the cycle again and again. The goal being tincture that is very very potent.
I get around 40g-60g of kief every 3-4 months

Alternatively stir your kief in enough to form a mobile slurry and filter it.
Resuspend your solids in another portion of alcohol.
You’ll get much better recovery and final concentration control if you are somewhat generous with the alcohol up front. Then let the alcohol evaporate til you get a thick material. Then you can dilute with as little alcohol as you choose. Warming it helps at this stage.
My experience is that using not enough solvent in the extraction step causes far more problems than it avoids. Is there any reason you would not choose to do a quick extraction with say a 200-ml portion of alcohol followed by two 100-ml portions for the 40 to 60 grams of kief? A quick multiwash like this gives you more and cleaner extract.
Evaporate this down to 100 ml, ideally in a container of known empty weight - or as far as you can get it, then redissolve to a known weight/volume for your strong tincture.
I recommend this sort of procedure over trying to jam much kief into little solvent. There comes a point (for me at least) where a few bucks of extra solvent saves me the hassle of working with a viscous “kief mud”.
As @Fadedawg says, you reach a point where the extraction gets slow and dirtier.I'm starting with 750ml of Everclear. I don't want to dissolve and add more later because it costs me 90 dollars a bottle. The kief comes from my trim anyways, so I'm not wasting my good flower. To be honest, it's all just bonus at this stage. My main concern was just that eventually I'll put the kief into the solution that I have and it won't dissolve....which would be a waste. But if you're saying that won't happen then I'll just keep adding more until it's potent enough. At that point I'll make another 750ml from a fresh bottle...
The liquid goes through a coffee filter so it's not thick at all. Will it eventually get thicker?? If so, should I start straining it through a filter with a higher micron size?

Chemists have a technique called countercurrent extraction. If you have batch 1 of kief, add portion A of alcohol and filter, then wash your solids with portions B and C of alcohol. When batch 2 of kief comes, wash it as well on the filter with portions A, B and C in order. I’d push it to wash batch 3 with A, B and C and maybe alcohol portion D.
Portion A should now be over 50% goodies.
Batch 4 of kief gets washed with B, C and D.
Batch 5 gets washed with C, D and E in order.
lather, rinse, repeat
If you get kief batches often enough, and store the letter batches on the freezer in the mean time, you should have a simple and alcohol-sparing “system”. It is important not to lose track of your letter portions of liquid. If you maintain the order, you’re doing a simple and efficient countercurrent procedure.
Your coffee filters should be good for every filtration.
Does this method sound useful?

ive done about 50/50 but what i do is let it sit with water a few times until its clear than do it with alcohol it is alot cleanerI have 750ml of Everclear 190. I'm curious what is the maximum amount of kief I can dissolve into it to make the strongest possible sublingual tincture. In theory I can add around 40g of kief into the mixture every few months.
Where do you live that Everclear is $90? Holy crap!! It is like $25 or $20 for off brand here.I'm starting with 750ml of Everclear.
