I wasn't around back then to know any difference, I've smoked stuff from the 60s, 70s, 80s and so on recently.
The idea of a choice aged OOP tin in my cellar is much more appealing than the idea of opening and smoking said tin. I still buy one from time to time but frankly, I have had so many just down right delightful smokes from fresh tins, I really enjoy what I can get now.
I am still trying to experience the aged tobacco Nirvana. It still hasn't happened. There have been some great smokes of things but they were maybe slightly better than current production tins that are never sold out...
All that being said, I have started opening some of those older tins recently to try and find a little Shangri-La.
The best smoked I've had in the last 12-18 months was probably a toss up between a tin of Sunday Picnic or one of Regents flake. Both 22-23 vintage, both went from meh to wow with a little air time in the jar post tin popping.
I really enjoy this hobby.
