I made this by taking chocolate fudge coffee grounds and PG and mixing them together in a glass bottle. I then boiled water and sat the bottle in the boiling water for 45 minutes. This let the flavor transfer to the PG which I then strained through a coffee filter. After that it was a simple DIY mix with the flavoring I made and some extra PG, VG, and Nic. Tastes wonderful and might be my best liquid to date.
How much coffee grounds did you use in how much pg for the flavoring? How strong is the end result of the flavoring? How much of the flavoring did you end up using in the final mix?
It was a test so I kind of winged it. I'd say it filled about a fifth of the way up a 30ml bottle. Which I then filled the rest of the way with PG. The end result was about 8~10 ml of PG based flavoring and I used about 4 ml of flavoring and 4 ml of PG the rest being VG and VG based Nic. It's just right flavor-wise not too strong and not too light. Tastes just like if I brewed a cup of coffee with it.
I have been doing this same thing with tea. I prefer max VG so I make a tea + VG cold tincure, shake it every day for a few weeks then filter it into a vial. Then I make tinctures with 190 proof alcohol also using tea. After incubation and filtration I add a bit to the previous mix just to thin the VG a bit but also bring some flavor to the party. I also occasionally add a bit of ultrapure H20. Doing this, I can achieve a real nice consistency and the high VG content gives me some pretty nice clouds as well!
I have yet to try coffee and this fudge coffee sounds amazing congrats on the sick batch homie I might have to give a mix like this a run as well.
From previous threads I've read, there are risks when deriving natural flavors, they can contain oils that are not good to vape.
