So how does one winterize? Is it something I do immeditily after doing my BHO extract? I add 91%+ ISO (or everclear) to the just sprayed BHO and then I put it in the freezer?
how i winterize:
phew. sooo, i just purchased my everclear about 2 weeks ago.. picked up 6 - 1.75 L bottles! hope i didnt clean them out :]
i just checked the website, says they are out. i hope they restock, and continue shipping!

ok. so, step by step:
i now start off with my butane and everclear straight out of the freezer.. (seems like you get a better spray out of chilled butane, and i use chilled everclear just to keep things preserved :] )
spray butane though column into collection dish.
boil off tane until oil becomes less runny. (bubbles barely seem to move by this point.) If temps are above 70F, no need for any fancy heating elements, lately its been 80F + around here, simple outside purging.
i add the everclear to the bho while it still has some run to it.. ( i add a good amount, over 5 times the amount of bho oil.. )
i then wrap some food wrap over dish, and place in freezer. ( be sure you have your freezer set at lowest temp)
dont rush this part, give it minimal 48 hours for the magic to take place. ( i once winterized in freezer for 9 days, seemed to have no ill effect)
after winterization, rig yourself something like this to filter out the gunk. collect the goods under the filters in a pyrex.
it will take some time to strain the liquid, so try and get your entire strainer rig to fit inside your freezer while this takes place.
here is where things get fun.. and people can differ, but! after you have the goods collected in your pyrex, boil off ethanol @ 95-110F .
the liquid will eventually start to bubble up, and most the ethanol will have been boiled off..
from here on out, i remove from heat, and vacuum purge no heat and get my muffin :]
