ABV Concentrate experiment: What method is best?

Ah, that makes sense.
It shall be tried.
I'll report the outcome.

my brains in a bit of a fog at the moment and im unsure why i would need to filter the product a second time there shouldnt be any particulates left after i run the bho though the abv in the first place. i am considering adding most of the oil into some brownies but since im just making edibles would all these purification steps be overkill?

Butane has a different polarity than ethanol. Butane pulls out the cannabinoids but also a small amount of naturally-occurring plant waxes. Ethanol pulls the cannabinoids but can't take the leftover plant waxes, which is why it's filtered a second time. If you're planning on eating it, winterization probably won't have much noticeable benefit? I'd spring for it if I were to make a run of oil to pass on to other people.

I found these on the interwebs





Think I'm gonna try what that guy's doing

P.S.: Why is it called winterize? [I'm German I don't get it]

Got to read that topic. I have a bunch of vaped herbs and some are already soaked in 95% grain alcohol.
I may pull the trigger on some titanium so I have to get into making wax.

I has boiled the herbs before putting them in the alcohol. I will simply extract a bit of the liquid in my jars with a small syringe, lightly stuffed with cotton to filter plant matter, then pour it on a flat glass surface, placing it under my IR lamp, windows open. I will do micro amounts to avoid concentration of toxic evaporates. Scraping it with a razor blade after it has dried. Ghetto old school.

I really don't want to get into butane extraction :/ The stuff and weird odors you talk about are a turn off. I have some quality butane but I don't have the accessories to extract properly

Weird odors are the result of using impure butane. I ONLY use Vector 5x Refined in my BHO runs and my torch. I was also kind apprehensive about messing around with butane, but once you've done the process one time, it becomes a whole lot easier. The biggest danger is proper ventilation... I go to the table in the backyard and do fine.

Congrats on using 70% butane 18% propane Vector is Overpriced and Overrated. Look up your MSDS people.
propane has a higher vapor point meaning it is harder to evaporate out and Cannabinoids are less soluble in propane. Do yourself a favor switch to Burnzomatic(35% N-Butane and 65% isobutanes) or comparative butane.

It's actually apparently 11% propane. Congrats on reading the MSDS. Propane is the propellant.


Butane's boiling point: 30.2°F (-1°C)
Propane's boiling point: -43.6°F (-42°C)

Having two different solvents working to extract at the same time would actually be more beneficial, no? Please don't tell me you believe that butane extracts EVERYTHING out of it? The quality of your end-product will suffer if you try to run butane through it until you get all the cannabinoids up...

both propane and butane extract with the same structure in the molecule but butane has more Hydrogen bonding sites. forgive me for miss quoting the MSDS ratio i was operating on memory probably shouldn't do that while medicated. The ideal hydrocarbon chain similar to butane/ propane is hexane though it is liquid at room temp.

I wish I had found this thread earlier. I have some ABV that has been soaking in ISO for about 24 hours. I was about to strain and start to evaporate - am I way off? Or should I throw it in the freezer overnight?

I would strain then freeze for 24 to 48 hours then filter it again strait out of the freezer

I hope you're going to cook with that oil. That's a long soak for iso; even with winterization.

Really? I am getting too old for this shit - I have a ton of abv and have never tried a concentrate. I thought you soak in ISO for 24 hrs, strain - evaporate - scrape and smoke. How badly am I doing?

That's like 23 hours 59 minutes and 30 seconds too long.

Edit: Iso washes must be kept under 30 seconds or else too much other stuff is extracted from the plant. You can cook with that oil though! Makes caps or even turn it into a tincture. That batch will not go to waste. I've only made ABV qwiso once and it was my first time trying qwiso. Personally I'd try the mason jar bho method, I'm going to start doing that for my once ran bud and abv. I can teach you how to make some good qwiso, as can others. I learned a lot of what I know from FC.

i just posted these 2 QWISO videos last week from youtube.. this is my favorite way... maybe try it another time.. the BHO mason jar method would probably turn out better though...

cool.. i'll look out for those pics.. iv'e been wanting to try that since i notice this thread.. i always end up eating my ABV though

A tincture huh?
