Glycerin Tincture

I've explored numerous methods of extracting THC into tinctures. The alcohol method has a tendency to sting the mucus membranes of the mouth. I just finished a batch of the following for those looking for a recipe with less alcohol and a sweet taste to it

.

Step1) Take a previously made marijuana tincture

Step 2) Pour the tincture into the top of a double boiler . Add an equal amount of glycerin
(4 cups of tincture to 4 cups of glycerin, for example.)

Step 3) Over very low heat, a slow cooker on low works the best to cook the mixture until it has reduced in volume by half, or 50%. The alcohol will "cook off" while you are doing this.

Cooks Note *****Depending on the type of alcohol (for example Everclear 100 proof) and the percentage of the water volume in the alcohol it could take several hours to cook down. I left mine on low for about 8 hours and used Everclear to make my basic tincture recipe.

Step 4) Once the mixture has cooled, store in glass bottles refrigerated.

The key here is to reduce the alcohol and not loose the THC by cooking at to high of a temperature. Never boil at extreme tempatures or you will destroy the THC in the tincture.






temperatures should never exceed 175 degrees farenheight, or thc starts degrading, very fast.

225 would be the maximum temp. THC will vaporize around 300 to 370 degrees depending on the accuracy of your thermometer or oven temp. With this tincture you are only evaporation the alcohol which boils at a much lower temp than THC will evaporate at. This tincture will incorporate the two mixtures together and evaporate the alcohol. The alcohol will extract more THC from the MM than glycerin will.

Will cooking oil work instead of glycerine, to mix with the alcohol tincture & put on the double boiler? Something like Canola or Olive oil?

Thanks for this recipe!! I just got an alcohol tincture & we don't drink so the smell makes me queasy.

Thanx for this recipe, I quit drinking a few years ago & can't stand the alcohol smell of a tincture I just bought.

Was wondering, can Cooking Oil (canola, olive?) be substituted for the Glycerine, is the Glycerine also a type of oil?

Thanks again!! :thumbsu:
