When using ethanol do thisHowdy All,
I have been a small-scale grower for 35 years. I prefer smoking bud, but I have recently begun to appreciate vaping, especially after I mixed some menthol flavor in my last batch.
I have decided to try my hand at concentrates, specifically Hash Oil.
I have tried the BHO method and produced some awesome oil, but butane is a tad pricey and seriously freaking dangerous... I knew a guy in Louisiana that was blasting outside and his cat walked up during the run. Yep, you guessed it. He touched the cat, shooing it off the table and set off an explosion.
Not, that I am worried... I just know how things happen.
I have done an Ethanol extraction and it was good, but the chlorophyll changes the taste and I love the amber liquid. Did the sunlight thing to get rid of the chlorophyll and did not care for the result.
Now I am considering a methanol run.
1. Grind bud.
2. Decarboxilate in the oven at 220 F.
3. Place in glass container covered in Methanol. Store in the dark , periodically agitating for 24 hours.
4. Strain through cheesecloth.
5. Boil off most of the Methanol using a stirring hotplate.
6. Add EtOH wash (190 Proof), agitate and boil off once again, this should also remove all of the remaining methanol.
This should produce a beautifully clear amber Hash Oil, without the danger of turning yourself into Richard Pryor.
Has anyone tried this process? Is it better to decarboxylate before the methanol?
Grind up material and freeze it
Get the ethanol as cold as you can
Mix the two together in a jar for no longer than 30sec
Pour out on glass baking dish to evaporate or run though an oil distiller. I prefer glass ones.
Further refining can be done doing a short path distillation method but this is very time consuming, has a high upfront cost and takes practice however the thc-a distillate you get is out of this world. Almost 100% thc.
The quick wash will produce a beautiful golden amber and retain a lot of the terpines responsible for taste. The longer you soak the only things you are extracting are chlorophyll and tannens. All which produce bad tastes and have no value.
That's old school honey oil made the old tried and tested way.
Happy smoking. Hope this helps.
