It was McClellands Virginias that made me a Virginia smoker. There were a few others I'd smoke too, but McClellands checked all of the boxes for me. Once, McClelland left the shelves, I wanted to find something I liked as well, because European Virginias just didn't do it for me. So, I just took an interest in the C&D line up, a few of their Virginias I do like more than European Virginias, but I fell in love with their use of burleys.Exactly.
At the same time, those who missed out on McClelland didn't miss anything super magical. If Samuel Gawith Full Virginia Flake went out of production today, it would probably be even more legendary than the McClelland Virginias. FVF is almost universally praised among Virginia smokers as an excellent VA flake, more so than McClelland blends were praised when they were in production.
I think the key is just exploring... it's ok to try a no longer available blend, but don't do it looking to stock up on them, unless you have more money than sense.
