Right out of the mail mine tasted fantastic. Now its about 20 days old and as far as I can tell, the harshness has decreased a bit, and it tastes like the flavors have synthesized more and formed a more full bodied taste - rather than an "in your face" blast of flavor I got when I first tried.
Honestly I couldn't say when I liked it more, would probably change based on my mood. All I know is its the greatest juice and could vape it all day - like Wharf Rat said, try it when you get, you might just love it on day 1. IMO its not worth steeping as much as it is just conserving it in general, and this isn't one of the juices that 'needs' to be steeped or will achieve fantastic results by steeping. Well maybe, but its not worth teasing yourself!

Day after day you will see the change in flavor for yourself and enjoy very toot. If nothing else, by the time you finish, you will have a very good idea of when you think it is at its prime and will know for next time. Once you try it, you'll know when you are in the mood for it - and when you are, go for it! Its so refreshing.
