My friend who is a retired Food Science Professor at Cal Poly SLO is now working for a company in the medical cannabis field. I asked him how he would do an alcohol extraction and this is what he told me:
Freeze flower and alcohol separately. 1 gram flower loosely broken up per ounce of alcohol. Higher proof is better. Mix and shake vigorously for 30 seconds. Return to freezer and every 15 minutes agitate, to either 45 minutes to an hour max. Pass through filter and sparge with fresh spirits. This will supposedly extract 99% of the available cannabinoids without damaging the flavor profile.
Well, I might adjust my sample techniques based on your post, but I still want to try agitated vs non.
Again my goal is to try and reduce the amount of peripheral matter that finds its way into the extraction to have a higher quality oil.
If the amount of cannabinoids not extracted because of non agitation is letās say 5-10%, I can live with that if the quality of the oil is that much better.
Multiple variables is called the āshotgun approachā and does make it harder to pull meaningful dataā¦frozen extraction greatly reduces the amount of chlorophyll in the extract which may also contribute to the thickness of your finished material.
What color is your tincture when you strain it? Green? The frozen stuff is kind of amber.
My very first batch of FECO was sugar leaves from very sticky Afghani.
I got a 10% return and it was every bit as strong as the second batch I made with buds. But to the trims credit, it was just the sugar leaves and they were very sticky!
No doubt the trim packs a punch @AAA, I did manage to salvage something good out of two spoiled amnesia autos and a blackberry kush from the trimmings. They made great hashishish!
I found this thread last night @Missiles. How this journal (that lots of my fav members post on) went under my radar is beyond me lol. Iāve got the button set to watching even though Iām only 200 posts in lol. Iāll be back with a proper critique after I catch up but so far so good
