^^ There you go Camino. That looks like your method, with an added pass for a stronger concoction.
Question about making your own DIY flavoring

I think next time I'm gonna get one of those plastic Melitta filter holders that just sits over a cup.
Maybe. That's a cold infusion - a hot extraction will get the oil out of the coffee a heck of a lot quicker.
Be careful if you heat your base liquid in the microwave. I'm not sure about PG but VG releases some fairly nasty chemicals if you overheat it. I tried it in the microwave once and after that I've just heated a container of my base liquid in a pot of boiling water.
If you heat your nicotine in the microwave it changes. Was warned about that, its not nicotine anymore. The molecules change it to another thingy. Not too technical on the wording lol
Of course I would!
The LR atty is 2.0ohm, I just prefer them in the lower 2 range. The drip tip in the picture I got from the Vaporescence store (which is about a mile from me), the nice guy there sold me 2 for $1 each. That's also where I got my passthrough. The drip tips are found many places online Drip Tips Colored Swirl - Delrin
I only drip now, I tried the Boge LR Cartos and still wasn't getting as much flavor, etc. I haven't tried the tanks because I used to switch flavors constantly before I found my all day
I'm just back from grocery store, I'm going to try this over the weekend/next week. I myself am not a kawfee drinker (though I love the smell). I am hoping to make some for a couple of vaper friends, who both are big java guys (and not programmers....). Without knowing, I figured stronger coffee would take less extraction time. I picked out some Peruvian beans, that smell pretty strong. I'll grind'em up, and start on it tonight.
Did you put it in the fridge while it dripped/drained? Or just leave on the countertop?
I got this to work, somewhat, still needs some tweaking to make it more consistent and repeatable. Here is what I did. I took three small scoops of coffee beans, ground them very fine. I did the afore-mentioned cold extraction (thanks for the links and suggestions) in straight PG. In my case, I was low on PG, so I just measured out 40 ml of PG to use. The suggestion of soaking the grounds in a filter was good, but the only filters I had were the funnel/cone shaped ones.
I spread the grounds out in an approximately 5 inch square Pyrex dish, and simply poured the PG over it. It was really not enough liquid for the solid material I had. I stirred it a bit, and had a very strong coffee-smelling semi-solid. I let it sit for three days, stirring about once a day. After three days, I spooned/poured the coffee sludge into a wine glass, that I had taped two funnel type coffee filters to. I taped them up, to keep the bottom of the filters out of the accumulated liquid. I did this just on a counter-top, at room temperature.
I let it drip another day, and started trying it. First test was zero nic, 80/20 pg/vg, 10% coffee flavor. I gave it a half-hour hot water quick-steep, I thought it was way too weak. Next batch, zero nic, 80/20, and 20% coffee. This was a little better, still thought I could taste more VG than coffee. I was making this test batch for a friend that is a hard-core coffee drinker, so I doubled it again to 40% coffee and mixed it to 18 mg/ml. This is a higher percentage of flavor than I would like to vape on a regular basis. I could taste some coffee in this one, so I put in about 5% Amaretto, and sent it to my friend.
But? Now, a couple of days later, my 20% coffee batch is very much stronger tasting. The steeping does not just hold true for Lorann (or whatever) candy flavorings. Again, I am not a coffee drinker, so what I consider strong may be baby food for a real coffee junkie. My friend likes black coffee, so I did not experiment with any cream or vanilla flavorings.
He will get it in a few days (and steeped better, by the time he gets it), I will see what he thinks.
I will try this again, here are some things I wish I could do different?
I wish there was a good way to get a reduction, without just boiling it down. Coffee has a lot of oils in it that are released by heating, I don't think I want to vape that. I know that boiling VG is not a good idea, as far as vaping, I haven't heard about PG.
Alcohol (probably PGA) would be good on one hand, because it will easily evaporate down and give a stronger concentration. Will cold alcohol extraction also get the oils, or is that only released by heating? Extract with PGA, do a reduction, then store in PG for mixing would be a nice way to handle it. I am not a chemist, but I do understand that different things are soluble in different liquids. Since I have an idea that "coffee" is a complex flavor, I don't even know what all makes the flavor, much less what each compound is soluble in.
I will try more PG. I didn't get very much volume of coffee flavor liquid, and it has finished dripping through the filters. It still looks "wet", it makes me want to squeeze it and get more out.
How can I get this more concentrated? Freeze-drying comes to mind because it can reduce solvents, but that takes more equipment than just sticking it in your freezer.
