winterizing BHO

It is faster with vacuum, but you can minimize the time by keeping the films thin, so that the alcohol doesn't have far to go at around 125/130F.
You can tell when the alcohol is gone by watching the bubbles, and by taste and smell. You want to stop purging when the larger irregular sized bubbles cease, leaving only the small fizzy equally sized Co2 bubbles.
What is the best way to purge out remaining water and Ethanol to achieve a great taste and smooth product without a vacuum Chamber???? Hypothetically speaking of coarse if someone where to purge the winterized oil on 135-140f (knowing the Monoterps will be gone anyway at temps you need to purge out ethanol and water) in a thin film for 10+ hrs, nothing but decarbing Co2 bubbles and It is still kinda harsh smoke?? Not the biggest fan of using polar solvents without a vacuum purge, maybe thats what ya need to make this smooth and Absolute?? Can Anyone with experience heat purging and trying to keep terps around after winterizing Bho wiegh in here??
A Buchner funnel, a #1 Whatman lab filter, and a vacuum pump. I can post a picture once I'm back home.

You have to remember that by decreasing the pressure, you'll not only be increasing the volatility of the ethanol but also of the terpenes. The main advantage of vacuum purging therefore, isn't the ability to retain greatly more of the monoterpenes, although you may retain proportionately more of them. The main advantages are the decrease in the temperatures used, aswel as the decrease in evaporation times. It's the increased heat and duration that causes degradation in heat and air sensitive aroma compounds (and cannabinoids). That's not to say that you can't still make some very tasty extracts with hot water or simple air drying techniques. The more volatile monoterpenes like pinene and myrcene have boiling points from 55 °C to 68 °C above that of water, so you can still retain a fair proportion of them with careful purging.

Perhaps you could include a pic of one of your traps, GW?
Here is a trap that is ready for plumbing, and the design of the one I am making for the rest of the trials, which will include a filter section not on the one in the picture.

is this pump too much to vacuum assist ? works great for purging

love the setup gw. I'm just starting my experiments with winterization and really appreciate all this info you guys share. any experiments with blasting directly into ethanol purging from there. I wanna see what happens.

GW Have you found any difference in using 190%everclear versus the Alchemical ethyl grape solution?
Site moved, deleted, or does not exist flag......................
An azeotropic ethanol/water mixture doesn't care about the source of the converted sugars, though methanol is produced from fruit pectin, so would ostensibly be higher in the grape mash than the grain mash, before fractionally distilling to remove methanol and the ethyl acetate in the heads.
After fractionally distilling, the 190 proof, ~95.6% alcohols are ostensibly the same, but experimenting with white lightening by others, I can tell the difference in the taste between corn squeezings and fruit neutral distilled spirits at 120 proof, sooooo am tongue and cheek and plead ignorance at higher concentration.
Hi everybody! I am new to winterizing my BHO and am currently on a run as we speak. I may have missed a part or two through these amazing threads and couldn't find an answer for a few things:
When exactly do you pour Everclear (ethanol) to your BHO soup? I allowed mine to naturally evaporate with the hot water double boiler pyrex bath for a bit until all bubbling stops and then mixed my everclear. after doing that, I had stirred allowed to sit for 30 mins, (did I wait too long to let the fats solidify?) and then poured into 6 different cups with unbleached coffee filters. Allowed that to sit in the freezer for 24 hours and now I am waiting for the evaporation process to happen with the same water bath but kept at around 175-200 with a hot plate and pyrex bath again. I'm left with a milky cloudy residue on top and a golden layer on bottom. It's been 4 hours since I've started the evaporation process and I'm worried I'll be stuck with a less inferior product!
Also about the scraping process:
How do you guys scrape into a parchment paper to vacuum purge in an oven? I have a new toy at the lab and I would love any tips to getting nice uniform shapes on my parchment paper to put in my oven (at 95 degrees? full vac at -29 mmHG?) for a few hours
Things that were used:
151 proof Everclear (750 mL)
~240 grams of high quality sugar trim leaves I cut from my harvest myself
8 cans of 300 mL Power 5x butane
THANK YOU for your inquiries. seriously, I have made plenty of crumble and honeycomb from threads like this and I'm finally catching on and trying to be apart of this community helping others as well

Better to use 190 proof, because alcohol is easier to purge than water.
You can add the alcohol before the bubbling stops, but I add it when the liquid butane is visibly gone. I then filter it to remove any particles and place it in the freezer for 48 hours for the waxes to coagulate.
I then filter it again to remove those waxes, before evaporating away the alcohol to leave the oil.
Just scrape it with a blade and place it on a parchment in a thin film. You can warm the parchment up in the oven and tilt it to spread it around, or chase it around with a heat gun.
You can also finish it in a thin film in the same Pyrex dish that you evaporate out of and scrape it up afterwards.

is there a difference between HEXANE.. and HEXANES? I got a bottle off the net of labgrade hexanes.. I have no clue if I can use this.. can u use hexanes to winterize?
Yes, there is a difference between the simple Alkane n-Hexane (normal) and hexanes, which includes aromatic Alkenes.
You can extract with Hexanes and winterize with a polar solvent like alcohol, but you can't winterize with a non polar solvent.

So to be clear here, once we have filtered out the waxes and we are left with our oil ethanol solution you guys are just vacuum purging at ambient temperatures? Would it not be advantageous to hold it around 100f with a hot plate or something? Or will I really end up with fully purged shatter if I just vac at room temp?

And I've seen people saying you need 15-65ml/g of oil before winterization. Is that really necessary? I have my oil completely dissolved in some amount less, is it possible I could be messing something up by not adding enough ethanol even if it appears to be dissolved?
