U didn’t say how it tasted…? Regardless it seems to work for you
that’s great…
I’m not a big fan off VG PG etc etc and other emulsifiers
So I go the long way…for a pure cannabinoid oil As long as I use a
C cell type cartridge & 3.7 v pin setting.
This article got me to where I am today & couldn’t be happier, It’s like the 1970s with good Hash Oil all over again—

CANNABIS OIL QWET EXTRACTION BATTLE OF THE WASH: DRY ICE VS. FREEZER
Google it !
Here’s what I do, yes it’s long, but very simple once you do it once or twice !
Taste is outstanding and no decarb necessary.
My pure oil technique:
—Homemade (licensed MO Medical Cultivator)
I usually use about 12 to 14 ounces Generic Everclear 190proof to 1 ounce lightly ground very dry herb (low moisture content)… 25 minute mix soak time, after the Herb & Generic Everclear we’re 1st sub-cooled both in separate mason jars which were cooled to
-50/-60f range in a sealed cooler with Dry-ice on a screen placed above herb & generic Everclear jars (dry ice gas evaporates downward as it is heavier than air, minus 115f temp over mason filled jars.)
Why so cold—““”You might say that the fats and waxes are slowed to an extraction crawl, but the Cannabinoid oils will extract at a fast past walk vs crawl— basically you’re just freezing everything out you don’t want !!!””
(extremely important to keep -50f or Minimum of -40f until “1st filtering”completed)””,
Of course alcohol and herb are in separate Mason jars at this point cooling down.… Once The alcohol and herb are sub cooled & combined (mixed in 1 jar) gentle stir 3 or 4 times during 25 minute soak, & shut cooler lid fast to keep mixture sub cooled…VERY IMPORTANT.
Note: Place alcohol and herb in the freezer for a night before doing the sub cooling.
((4 Ozs of herb Max per run for me, Grind herbs using kitchen “glass peanut hand grinder”— comes out about twice the size of joint material or what ever u have to grind, I would not use a herb grinder, Personally I think it grinds it too small.
—1st Filtering: After soaking herb/alcohol 25 min …filter the alcohol extraction off “very fast” while still sub-chilled cold using 75um filter. (I use ice Hash bubble bags, they separate alcohol oil wash
“VERY” fast or use silkscreen material (Readily available),
filter into glass Pyrex bowl/dish. I find these Pyrex dishes used at Goodwill or Savors.
—2nd filtering into another Pyrex dish use a 25um filter (use the 25 µm bubble bag or a brown coffee filter which is also 25 µm, this removes the remaining sediment), Obviously the first filtering is the “most important” (remember the whole purpose of the super low freezing temperature is to isolate all of the “”fats, waxes chlorophyll, & other undesirables”
that you “DO NOT want in your Vape oil”)…
Now if done correctly, you have a Golden liquid…
Evaporate Golden tincture in Pyrex dish using controlled temp hot plate or electric skillet & add several drops water helps keep the oil from over heating (Or let it evaporate naturally in the sun covered with cheese cloth, and no you will not degrade THC In a short period) I like to keep skillet temperature under 160f this keeps the alcohol usually under 140f… I preserve many Terps, but I am not a Terp hunter !!!
“”MUST Have a Fan”” on & blowing over dish if utilizing heat, NO NO NO open flames… keep well ventilated
fan fan fan…Or again let it evaporate naturally and finish it off on a coffee pot warmer or alternative.
&
When the alcohol mixture has reduced to a couple of ounces, pour it into a very small glass thick jar that you plan on storing the oil in. (Like a used Penzi spice jar I love these little easy to access jars)…
(you will also use this jar to remove all of the remaining alcohol and whatever water is in it, I do this by putting it on the hot plate of my coffee machine or a skillet keep temperature under 160°, this is the “longest”process step because you occasionally stir the oil with a toothpick to see if there’s …“any any any”micro bubbles, if so you are “not done”… can’t stress this enough…!
Have patience, because you are not done until those micro bubbles are gone and I mean micro !
(for those of you that want to argue,
food grade alcohol & water pickup is 100% evaporated @ this point).
Fill a nice C Cell cartridge and have fun
with your adjustable Vape pen set at 3.7 V…(( I Sometimes use a small amount of PG/PEG 1Gr To 5Gr ratio as a thinner, but not very often, when the oil is pure like this free of undesirables you really don’t need it… and yes occasionally I will add some passionfruit Terps))
Done
