I recently got a tin of Deep Hollow from a brother here dated 2013. Of course, I opened it right up and got into it. Research revealed to me it was a blend that had something to do with Hobbitown. OK, whatever............
I smelled apple. Like green apple. (No ketchup) It is described overall as an aromatic on other sites, and I have to agree. However, it is not some heavily PG laden Burley/Cavendish concoction one would be inclined to eat rather than smoke. The contents of the tin were a tad damp, but not so much I felt obligated to dry it.
As I smoked it, I had a minor dread lurking in the back of my hat rack (head) that this blend might ghost my pipe. So far, I have not noticed any residual effects. I enjoy it as a morning smoke while enjoying tea or coffee, though the coffee seems to subdue the zesty sweetness. I think it would make a great hot weather smoke.
I don't get into it often. I did however buy another tin as a backup. So, I like it!
Grey Havens I have not tried.............
