How to make Vegetable Glycerin (VG) tincture

 VG Tincture (e-liquid)
Gather the following materials:
1 Crock Pot (or similar)
1 quart jar
Vegetable Glycerin (food grade…check amazon)
1 thermometer
Cannabis trim or buds
1 foil lined cookie sheet
Cheese Cloth
Strainer
Step 1:
Pre-heat oven to 250F. If using flowers, grind them up fine. Lay the cannabis out on the foil lined cookie sheet in a single layer. Place the cookie sheet in the oven, on the middle rack for 30 minutes. Remove.
Step 2:
Put all cannabis into your jar. I like to pack in as much trim as possible. Add VG to the jar, covering cannabis completely. Stir to break up any pockets of air.
*A note on how much to use. I use as much as I can fit into a quart size jar. I generally only use trim, although I have been known to add a couple of buds. If you don’t have enough to fill the jar, add as much as you have, pack it down, and cover it with VG. Its ok if it doesn’t fill the jar.
Step 3:
Fill Crock Pot three quarter full with water, or oil. I used oil this time around so I didn’t have to worry about having to add water to the bath through out the process. Water is fine, though. Place jar of cannabis mixture into the Crock Pot and turn on high.
Step 4:
Heat mixture to an internal temperature of 180F, stirring twice an hour. CAUTION: I advise against using any type of metal to stir mixture with. Metal against hot glass can lead to breakage.
Step 5:
Once the mixture reaches an internal temperature (place thermometer into mixture) of 180F, hold for 30 minutes (stirring once or twice) and remove jar from bath and place on counter and let cool to 80F (stirring occasionally). Repeat steps 4 and 5, 5 more times. This process took me a total of three days, with two hot/cold cycles per day.
Step 6:
When mixture cools for the 6th time, lay out 10 layers of cheese cloth (look in the paint section of your local hardware store if you are having trouble finding it) and place them as a liner into your strainer. Place strainer over a large bowl. Empty contents of jar into cheese cloth lined strainer and let drain for 15 minutes, using a rubber spatula to work the mixture around to strain out the VG.
Step 7:
Gather up corners of cheese cloth, and squeeze all of the remaining VG out of the material. Discard material when you are confident you have gotten ALL liquid out.
Dosing:
As with all edible cannabis products, start small and test the potency. Potency will depend upon the amount, and the quality of cannabis put into the material. I used all the trim from the last 5 plants for this batch, and it is strong!!
For me, personally, 1 ML works as a great daytime pain reliever, 2 ML is very relaxing and will help with sleep. For my wife, two drops under the tongue is just right, 4 drops was too much!
Things to do with VG tincture:
Take it as is. It will have a sweet, weed flavour.
Use it as e-liquid in a vape pen. Add your favourite flavours for a more stealthy option.
Make candy, gummies, salt water taffy, etc. Vegetable Glycerin is the base for many hard candies, suckers, gummy candies, taffy, etc. It can be used as a substitute for sugar in many recipes. VG is also a good sugar substitute for diabetics!
Add it to your morning coffee or tea to start the day off right! Remember…if you add too much, you’ll start the day off weird, so be careful!
Yield:
This particular batch made about 8 ounces of tincture.
Why does it take so long?
I know…it is a long process. BUT….it is worth it in the end, in my opinion. This was a much more complete extraction than just heating the vg/cannabis mixture for a solid 12+ hours, and straining (what I used to do, and it works…..just not as well). The key is in the frequent mixing, I believe. By gently stirring the mixture every so often, it removes the boundary layer and allows the cannabinoids to keep extracting into the VG…instead of “stalling out”. In the past I have observed trichomes still on plant material after as much as an 18 hour soak, on high in a Crock Pot. With this method, I couldn’t find too many heads still intact and on the plant material. This method resulted in MUCH more potent medicine.
