I buy the old straw about Virginia showing the most improvement, though I am first a burley devotee. I do believe burley can mellow in a nuanced way, and in the case of aromatics, the fading of flavorings helps the burley emerge. I suspect that the variables in tobaccos sourced from different places in different years make the benefits of aging highly unpredictable. Cosmic dismissed most of what I meant to say, but that's okay; I find the iconoclasm refreshing. I have had Latakia disappear entirely in a premium brand, no name mentioned, so I bolstered it with other condiments and smoked up the tin.
