Hi everyone I have been lurking here for several months. I bought some vapes based on the great info here: Glass VG, SSV (control shaft broke immediately alas, still trying to figure out what to do about it), cherry PD, walnut Woodeez, MFLB. I've been accumulating abv for a few months so I thought I'd relate my experience with it. I am in an apartment setting where excess odor could be a problem, and though I am legal in CA, discretion is the better part of valor so decided against simmering oil for three hours. The first time I tried just mixing up the abv remains of what had been about 3/4 ounce of herb with Wesson corn oil. I put the abv in a glass jar and poured the oil on it till the oil level was about double that of the abv before I put the oil in. I stirred and covered it tightly and let it sit for a couple weeks, opening and stirring now and then. Maybe 20 minutes after a stir the solids sank to a layer in the bottom of the jar, above which was a dark layer of oil. In a spoon this was a rich, transparent green. Floating on top of the oil was a thin layer of tiny, ground up and vaped stem bits, which taste somewhat like popcorn. I skimmed those with a spoon and left them mostly spread on the side of the jar. I then used the oil in two ways. Sometimes I would just dip a spoon in and take a teaspoon or two directly in my mouth, swirl around on tongue for a while and wash down with tea. If you have an empty stomach this can bring on a near instantaneous high. Otherwise I used two or three tablespoons in the making of fried rice. Also quite good and comes on fairly fast, within an hour.
I accumulated more abv, the remains of around 1.5 or 2 ounces. This time I ground them to a fine flour in a rotary coffee grinder. Remembering a Chinese cooking technique involving pouring heated oil onto a bowl of spices and flavor ingredients, I put the finely ground abv into a glass jar (from Adams peanut butter) and heated more Wesson corn oil in a saucepan to very hot but not smoking. I then carefully decanted this hot oil into the glass jar containing the abv. I wondered if I was going to shatter the glass but no problem. Be cautious about the glass if you try this - do it in the sink and have glasses on just in case. I did not measure real carefully but I was aiming to have the oil level be about 1.5 to 2 times the height of the abv alone. I was trying for a bit less oil and rather more abv in hope of a more potent elixir. The hot oil seethed and bubbled for a little while in the jar. I let it cool, covered tightly and left it overnight. This morning I tried about half a tablespoon straight up and chased with tea. Nice high, stronger than before! I think the taste is better with the hot oil treatment. The taste is surprisingly good.
Edit, several hours later: Gee that was trippy! Re-reading this I see I might not have chosen the best thread but in my mind at the time was the idea that abv has already been cooked at 385F or so; the only cooking with oil would presumably be to dissolve as much of the remaining essences as poss... So the temp or length of heating isn't really that critical for abv, I suspect.
