Yeah, it's a simple extraction but I'd never extracted anything before and it turned out pretty well 
I have some 80%VG/20% DW I keep around so I don't have to thin VG all the time. Filled a 30ml glass bottle 2/3 of the way up with a pretty good French roast I had, topped it off with the VG mix and stuck it in the microwave for ten seconds (I watched it closely - more than ten seconds and I'd have had a mess) then let it sit for maybe fifteen minutes. The coffee grounds absorbed all the VG.
After that I boiled a pot of water, topped off the 30ml bottle with more of the VG mix, took the pot of water off the stove and set the open bottle neck-deep in hot water and let it steep for another half hour then strained the result through a coffee filter into a graduated flask, which actually took quite awhile and I ended up with 15ml of VG-based coffee extract.
Got a dropper and dripped a drop or two onto a 510 atty and it did indeed taste like coffee - so I whipped up a test batch of coffee/bavarian cream/chocolate/caramel that turned out to be a pretty tasty vape after juggling ratios a little bit.
So - I've got 15ml of a pretty good coffee extract and a way to reproduce it fairly consistently. Like I said it's a pretty simple extraction but I was pretty proud of myself
