I recently started making my own liquid and I love it. I bought a complete kit from liquidbarn.com and I like it so far. My only issue is that some of my flavors I make hit really hard for the first couple of puffs, then they mellow out and taste fantastic. Is this caused from a lack of steeping? Or is this from bad flavor extracts. I admit I have been very impatient and haven't really been steeping my e-liquid, but most of them taste great right after they are mixed. Any advice out there for me?
