Shortly after starting to vape I at one time had probably 15 different coffee flavored vapes. I don't even try anymore. they pretty much all end up tasting like 3 day old stale coffee in the end. The best one I've had was
@markfm 's vanilla coffee and it was OK but close to the bottom of the tank I detected that stale flavor coming on. It's not a matter who or what my tongue just doesn't like them. I refuse to spend a lifetime and a boatload of money trying to find the one coffee vape that I like, if it exists
