I have been searching for a vanilla-extract-type eliquid, as I love the general undertone of it when mixed with other flavors. Kind of like a "dark" vanilla taste without sugary sweetness and NO floral-y-ness.
I just got in some madagascar vanilla flavoring from Flavor West that smells straight up like vanilla extract. I have it mixed up right now, I'll report back after it steeps a bit and I can sample it. Just based on the smell, it's the closest flavor I've had so far to vanilla extract. And at 15% flavoring, it's not very dark at all, so I'm hoping it will be coil-friendly.
