I've been mixing Cappuccino 36mg with various amounts of PG, VG, Lorann's/Liquidxpress flavorings shooting for an 18mg caramel latte taste. Haven't nailed it yet, at least not for me, but Bavarian Creme or Butter Rum seem to help tremendously. Vanilla, not really. Just an overall richness or depth that I don't get with the vanilla.
