James: More often than not, age doesn't help English blends over the long haul. I find after a few years, latakia -especially Cyprian - can dull a little. I also notice that varies from English blend to English blend. Because there are a variety of tobaccos in this one, some age could help, but I can't see it being a night and day difference at any stage. I would say much the same for most English blends after, say, the four to five year mark. Because this has a bit of Virginia, which ages well, you'll notice a little difference because that will age more than the other components, and give the impression that the Syrian latakia has weakened a little. Syrian latakia is less sweeter than Cyprian, so there's that to consider, too, although the sweetness in this product comes from the other tobaccos.
Having said all of that, I have cellared a few tins.
Btw, you may also want to check out MacBaren's Solent Mixture. Here's my review:
A well blended aromatic/English blend that burns well, cool, and even. There's a taste of rum, and a cocoa note or two from the burley. Overall, the Virginias are earthy and modestly sweet. The black cavendish adds enough of a vanilla hit that well enjoins the other sweet flavors without controlling them. The mild addition of Syrian latakia pushes a smokey and slightly woodsy flavor, adding complimentary strength to the other ingredients. The multiplicity of flavors are lightly amplified by a mild spice that I've tasted in other MacBaren blends. Best smoked in a wide bowl for full effect, and while it may not be an all day smoke for some, it's certainly a mixture you can reach for more than once a day. One of the better crossover blends on the market with enough strength to satisfy non-lat bomb aficionados without disappointing those who crave a stronger latakia presence.
