The batch variations were apparent from the first year, there's no way to extrapolate what it will smell like based on a date of manufacture or box style etc. The only way is to try the very bottle you a considering buying which of course is next to impossible. Or, you can buy a decant or a bottle on the secondary market from someone you trust and provided they know what the golden batch of Tribute smells like. The difference is very apparent - the good juice has bright, vibrant rose and super refined shimmering frankincense right at the opening with none of the muddled flat leathery lifelessness of the inferior batches. But after an hour or two its hard to tell them apart so even if you don't succeed in finding a "good" one, the "bad" ones are not all that bad really. Good luck!
