I love aged Virginias and Virginia/Perique blends. Other than these types, I don't have much experience with long-term aging. But I can safely say age makes a big difference when it comes to Virginia blends. Just for example, I had some Blakeney's Best Bayou Slices from McClelland with 2 years on it, then I had some that had 6 years on it. The 6 year tin was the clear winner. No harshness, very rich. The 2 year tin was good, but it was less mellow and while still rich, it was a bit lacking. Just my 2 cents.
