I have been smoking Virginias, Virginia/Periques, and English Mixtures for about 50 years and I have concluded that cellaring does wonders for Virginias which improve year by year virtually forever. Not so the case with English Mixtures, the Virginias improve with age but the Latakia will hold its character for several years but after about 5 to 7 years the latakia will start to fade and lose quite a bit of its fullness and drifts toward the bland. A few years ago I popped a tin of Rattrays Red Rapparee that had been tinned in 1970, the latakia was barely detectable. Welcome to the hobby, pipe smoking is truly one of life's little pleasures.
