    Winterization was a success (and yes I used unbleached coffee filter), old oil was really runny (too much lipids into) and dark, new one got a better aspect(thicker, less dark and more potent without bad taste).

    I lose 50% yield in the process and there is lot of "butter" in the coffee filter (not good at all) but my oil is without comparison with the old one.
    I think that i could make a better winterization if I repeat the process or if I let the jar in the freezer during a night (because I just let it into 3 hours)...

    if the qwiso was done cold enough, there shouldn't be much to remove by winterizing

    As Shisha said but everclear is definetly better for winterization so if you could start off with super cold everclear then your even better off. Quick wash then let it stay in the freezer for 12 hrs before filtration and purge

    I know this an old thread but has anybody tried this stuff for winterization? The local liquor stores to me have been sold out of Everclear for over a month but they stock this stuff.

    Googles what is winterization.

    I havnt found any information about using anhydrous ethyl alcohol for winterization really.... would seem to me that having less water to purge would be more helpful...
    Curiosity has me researching lol.

    I just did some marvelous QWET i got 0.12 from 1 g of bud :) ! First time i measure things and do such a small run.. anyway... It tastes awesome and it is opaque ... I do qwet strain then freeze then strain again and result is glass like substance that brakes like hard candy :). melts like colophon and rich aroma ..
    It is sad Ethanol is so expensive where you are... Here you can get a 0.8 for 4-5 $ ... 95% ..
    I guess in out small country when 80% of the population do moonshine :D they got to compete with prices :D

    When winterizing, is it ok to sprinkle some dry ice dust on the coffee filters to ensure that the filtration happens cold? My freezer's too small and I'm looking at using a cooler and dry ice to try this (again). Anyone know if mixing the bho solvent (alcohol post-chill) and dry ice is poisonous?

    Some pics of my winterization filtering, dry ice no freezer

    better to just wet it with chilled solvent. wetting the filter will aid I preventing oil collecting in the actual filter fibers and speed the inital flow.

    So I did something weird, and got some weird results. The filtration process pictured above took too long through a single filter and the dry ice was about gone, and once the filtration process isn't cold, it's half-pointless. So for quality's sake I purged what had already cold-filtered (came out bomb dark-amber shatter like most decent pictures on the net from old trim/shake).

    The weird part: I'm broke and need a good yield to last me until next payday, so out of desperation, I processed the rest of the stuff (still in 151 everclear solution) at room temp with all the used filters (bho blast and winterization), squeezing them all. I heated the solution (in a mason jar) in warm water to 140F for a minute to make sure everything (good and bad) was dissolved. I know that breaks a lot of rules to get quality concentrate, but like I said I just need to get by, and my starting material was kind of a joke anyway (bones and bits). And I'd never made "bad" oil before since I've followed tutorials well, and figured I could always just re-winterize with a future batch worst case.

    Result: Lots of plant matter - very green before scraping. The taste is very, very underwhelming, and is much like the the last hit of a desktop flower vaporizer - toasted popcorn with no "green" flavor, though not quite burnt or gross. The high however is the extreme couch-locking type... wow. I've been awake for 3 hours, no weed today yet, and I still feel "hungover" from my last dab yesterday. The texture is a thick gooey sap that will shatter out of the fridge (fine with me).

    I'm curious about how to keep some of that couch-lock high in my quality runs, but without so much plant material for taste reasons. I don't know if the (lame but not horrible) taste is from burning that trace plant material on my nail or some other unforeseen consequence from leaving the solution in my fridge for a week. (I suspect the h2o in my 151 EC may have contributed to high plant material levels over the course of a week - some material is h2o soluble).

    Both my purges are from the same starting material and blasting. Neither process ever saw temps above 140, but the dark stuff sat in the fridge (in 151 EC with all filters) for a week, and was then heated with the pickled filters) to 140 and re-coffee-filtered, ringing out/pressing the old filters. Purged normally (120-130F h2o bath 4 hours after liquid is visibly evaped)
