I was lucky enough to get some of this liquid about a month ago (no RY4 though) and it didn't really do much for me out of the mailbox. I'm relatively new to vaping so maybe I just can't appreciate it yet. I let it steep in the dark with caps off for about two weeks and revisited it. While the flavor and color has changed, it still doesn't really knock my socks off and it seems really harsh for a 12 mg juice. I ordered Casablanca, Malty Toffee, Malty, Caramel Capp, and Applewood. I really don't taste the flavors as they have been described by many reviewers and on Don's website. My question is; did I ruin it by taking the caps off? I've read other posts here about steeping and there doesn't seem to be any agreement as whether to leave caps on or off. Your opinion is much appreciated.
