I've got agree with Bob, the flavours in most of the carts is wimpy to say the least, there is a subtle hint of what it is supposed to be, and I do mean subtle ! Don't expect a named flavour to resemble the actual item it's named after, orange isn't, coffee isn't none of them are.
I buy flue cured, regular and cigar carts mainly, they taste ok for most smoking. I also have a flavour I call melange, it's the squeezings from all my used carts and has a unique flavour all of it's own which constantly changes, currently it has a caramel, raspberry taste to it, I added some of both flavouring to some carts, it was a bit strong so they got squeezed into the stock bottle, much more subtle now. For mixing I still have some tasteless liquid left over, not much though, I missed out on the deadline to get more juice out of China, before the paranoia of the Olympics hit. I hope they have a decent stock held for when the ban is lifted and everyone orders again.
