Can anyone tell me what flavoring Mt Baker Vapor uses that turns some of their juice dark brown? I've gotten some great juice from them and they all taste fantastic, but there's a few that I've found (purple ice and albino drake recently) that start out clear or lightly tinted, but during the day, they start looking like some motor oil. Don't get me wrong, their juice is great, but it kills my coils within a day or two and turns very dark.
Any ideas?
