I have to be honest - the first time I tried it, I got the same thing. We almost scrapped CLS entirely because we couldn't taste much of anything. CLS was slated to be one of our initial offerings, but if you look back into our history, we were actually open over a month before we released it. What happened during that month? Magic. I'm not the slightest bit disturbed or surprised, for some people it just takes time. For me, it was about 3-4 weeks and, for whatever reason, that bottle turned up, I put it in the dripper, and BOOM... never had that problem since. It's almost like your senses need to get a "lock" on it. Once you get it, it's unshakable.
Couldn't agree more, and I'm starting to find that PBC is exactly the same. At first the flavor was so hard to find but now that it's about 2 weeks old (and I've vaped it quite a few times) it's starting to come alive. I don't think it's just the juice that's developing, but my palate as well.
I think I'm a bit dehydrated today, but I tried CB for the first time today and couldn't taste any difference from CLS! Maybe it needs to steep some more. I've only had it a week, max.
I honestly don't touch CLS for a couple of weeks after getting it. Not every eliquid needs to steep but this one pays off. I also don't recommend ever leaving the cap off for more than one day at most. Have you put the bottle anywhere that sunlight or heat could've gotten to it? Even a couple of hours in a hot vehicle can rob an eliquid of it's flavor. Just want to cover all the bases.
