I've never tasted another blend that compares to Haddo's.
There is something about it that is so unique to my tastes which keeps it as a regular staple for me. I've tried it aged, by accident once, and it was still tasty. But for me, the variation that I get in flavour and sensation from a fresh tin is what keeps me interested.
I guess contrary to Sable, I like that "rough edge" but would instead classify it as a kind of spice rather than roughness. It's something interesting to me that makes me perk up every so often during a bowl, and it somehow brings out different flavours for me during those moments. The stuff is like a twisting mystery to me, and that is why I enjoy it so much. It is rare (in the grand scheme of offerings) for me to experience such variation in a blend. Amazing stuff.
It is one of those blends where I think it is a pity that in the long run, it will either become very expensive or non-existant... so I've stockpiled it. I've read a bit about how to "un-age" tobacco, but it is a bit of a hassle for my liking. I'll be truly depressed if the fresh stuff becomes a memory. The idea of toning down that spice and marrying it with everything else really brings me down... but not enough that I don't make sure I've got some in the future.
Long live Haddo's! What a curious, amazing blend of our times... It's what originally got me on to other Pease blends, but still remains my favourite of his line.
