I have vaped a lot of johnson creek
juice: both the original line and the vg based red oak line. Yes, some of it has a distinct taste of rubber. Mostly noticed it with the orig line, particularly the peach. Think the PG is more susceptible to this issue. Don't get me wrong, I love their
juice, but its hard to vape something that tastes like an old tire. I didn't notice the taste at first, but I mistakenly stored several of my bottles on their sides with the droppers installed and the
juice picked up the flavor of the rubber in the dropper bulb...YUCK! I contacted JC about the issue and they were super awesome about resolving my problems. They asked me what flavors/strengths this had happened to and rushed me a replacement order completely free of charge and without requiring me to return the original bottles. Kudos to JC customer service! The replacement bottle of orig smoke juice was fine, but the new peach still had an old tire taste...WT*?! And I'm positive its not from the dropper bulb this time. My suspicion is that the juice is exposed to rubber at some point in the manufacturing process and its picking up the flavor there, or maybe in a holding stage? I don't know. But ya, rubbery taste, definitely. Sure hope they get this issue worked out cause they do make some pretty tasty juice. Also be weary of some of the red oak flavors... bad atty cloggers (Swiss Dark is the worst one)
