I have to admit, I've never been a huge fan of English blends but Esoterica Penzance out of a big 1930's vintage Kaywoodie is indeed the poop.
Penzance was my go to tobacco for many years. Unfortunately, its now very hard to find. I resorted to smoking the McClelland Frog Morton blends and enjoying them. But I do miss my Penzance.
Mine was a gift from a friend a couple years ago. I totally forgot that I even had it until last weekend when I was blending up some tobacco and stumbled on this and some other samples. You're right, there are lots of sources for it on line but almost all of them say they are out of stock. What's up with that? Did they quit making it?
