I've been nursing a tin of Balkan Sobranie 759, that I bought in the mid 60s. I have nearly an ounce left, that has the consistency of coffee grounds. I need to put a small pinch of Blue Mountain at the bottom of the bowl, so I don't get just dust through the stem. The few times a year that I have a pinch or two, the stuff tastes great; quite a bit mellower, but the smell and taste are the same as when I cut open the tin. I'll be very sad when it's gone. But, I have a nice stash of Samovar to help me pull through.
