THC Ethanol Tincture
    #451794 - 07/27/10 04:01 AM (6 years, 4 months ago)

This is the basic procedure

1.  coffee-grind 3.6 grams of weed
2.  bake for 5 mintues in oven @ 325 degrees
3.  soak in about 5 ounces of everclear (90% ethanol?) (for about a month)


next is to heat the solution in a hot water bath to evaporate most of the ethanol.

There will be a lot of chlorophyll and other solvents, but this will be drank in small concentrated quantities; not smoked


is there any suggestions before this mixture gets boiled down?  It will be boiled with the ethanol solution at 170degrees.


can someone explain the logic behind freezing tinctures before and after it is concentrated?

would that help

I'd much rather put BHO in alcohol than have a disgusting cooked green mix of yuk

I believe Harry_Ballsach once said that it was unnecessary to cook the weed first if you are putting it in GD.  That guy is a professional scientist so I listened.  Correct me if I am wrong please Mr. Sach.

it is not necessary.  the last tincture i did worked great and i didn't cook it.

hell, after most of it had evaporated, my half-pint jar shattered and it all got mixed in with the boiling water :facepalm:

so i took everything out of the water, and lightly boiled it down for a few hours until there was 40ml's left.    so it was a Tea/tincture, but it worked GREAT

I would have thrown butter in there and then evaporated off the alc and had weed butter.

but why...  then it'd taste like shit.    it was THC + ethanol + water, so i boiled the ethanol out, and had THC and water.   

there is no point in adding fat because it won't help extract any more

Okay,


so now i want to know...

        After evaporating off some of the ethanol, is it good to have the mixture stay at 170degrees for up to 50 minutes?

would it be best to evaporate for 15-20 minutes at 170, then let it cool to room temperature and maybe let the rest fan-evaporate.



i'm  guessing, based on 1 previous experience, that about 40% of the 5-6mls i have will be boiled off in 15 or 20 minutes.

12. Extraction Temperature (revised)
I've had good success with extractions at 170 degrees fahrenheit. You'll note that my initial recipe called for maintaining temperature between 150 and 165. At 170 the alcohol mixture will be slightly boiling. Note that this is alcohol boiling not water boiling. Alcohol boils with very fine bubbles as opposed to the rolling boil of water. After 20 minutes the alcohol should be reduced by about half.

4. Simmer the mixture.
This is one of the areas that seems to be most debated. Many recipes call for placing the cannabis (unbaked of course) into the alcohol and waiting 2 – 6 weeks. The main concern with heating the alcohol is that it is “explosive” (not exactly true...it is however flammable).

The purpose of the simmering is to heat the alcohol mixture to improve extraction rates and efficiencies. Heating during extraction increases the motion of the molecules (basic physics/chemistry) and drastically decreases extraction times. The boiling point of pure ethanol is 173°F (78°C). We will use the water bath to heat the rum/cannabis mixture to just below the boiling point of ethanol.

Heating the alcohol mixture can be done very safely using a hot water bath. You will need an accurate candy or quick read thermometer. Place about 1 inch of water in a wide, vertical-edged pan (9” diameter x 3” high). Bring the water to a low simmer. The rum/cannabis mixture should be in a small (1 pint) mason jar. Do NOT cover the jar.

Put the thermometer into the mason jar and place into the simmering water bath. Bring the temperature of the rum/cannabis mixture to about 170°F. The alcohol should be just barely boiling.

You should have the oven fan on high. You will notice that any alcohol fumes are mixed with water vapor from the water bath and vented out the fan. This combined with the fact that you are trying not to boil the ethanol makes the process quite safe.

i've had the weed+everclear solution soaking for about a month now, i'm thinking it's as close to saturation as it even will be.  should i just open-air evaporate this?  i've got about 5-6mls

From everything I've been able to learn about cooking and extracting THC, I'm pretty sure it burns off at 250 or so...

If you cooked it like that first, you probably just wasted a good eigth of dank and a month of your life waiting for it to finish... :laugh:
