Hairball, I noticed that with my last 100ml bottle of BB, the last 20 or so mls were not as good as fresh juice. Not saying it was bad because I vaped it all, but I would say it tasted a bit darker or......... damn I can't think of good descriptions.......just not as fresh I guess. I bought that bottle in mid March I believe. So I think I am just going to buy 3 or 4 of the 18ml bottles at a time and eat the cost difference.
