Homemade Coffee E-Liquid

I have been working on getting a coffee/espresso flavor that actually tastes like I think black coffee or straight espresso should, and I have finally gotten one to work.

I took 2 extra bold K-cups and brewed the smallest cup I could (4 oz) in my Keureg that gave me 8 oz of strong coffee, which I proceeded to microwave to evaporate around half the liquid off. Then I opened the k-cups, and put the grounds in my Aeropress and did an inverted brew with the coffee, 10 ml of VG, and 5 ml of 190 proof PGA. I added PGA not to cut the thickness but to get the alcohol soluble flavors from the coffee. This super strong "coffee" got evaporated further in the microwave until it was approximately the right consistency to vape. I then mixed it 50/50 with 24 mg VG to get an end product with 12 mg nic.

It actually tastes like coffee!!! That being said, it tastes more like mass produced chain coffee shop coffee (ie. Charbucks or stuff you get when you buy donuts.) Being a bit of a coffee snob this is not the stuff I usually drink, but it still tastes like coffee, and in my book that is a win.

People have had luck putting coffee grounds directly into PG and microwaving it. Then strain out the grounds with (who'da thunk' it) a coffee filter. If you search a bit you could find the thread. Try 50/50 grounds to PG. PG is actually a powerful solvent. You could use PGA too as that might cover more ground.....no pun inteded.
