I have 8oz of Penzance which I've bought in May last year. It's been sitting in a glass jar since then and I've opened it today. I like it a lot but it's very, very mild. Won't buy it again.
On the other hand, Stonehaven is a one of a kind tobacco for me. I've only got about 5oz left and I use it very sparingly. Don't know when I will be able to get hold of some more. But, if the opportunity arrives, I will buy as much as I can lay my hands on.
I've been smoking VA's and VaPers for the last couple of months and I've almost lost my craving for latakia. I find Dunbar and Dorchester quite good and it's readily available. I also smoke a lot of Red Cake 5100, OGS and Escudo. But it's the Stonehaven I'm craving for!!!
