As I started smoking a pipe in 2013 nothing I currently have has anything more than about two years on it. I've smoked a sample of Star of the Wast and Bombay court that were four years old. Is there a generic optimum age? I suspect that is highly dependent on the blend and conditions, but wonder if there is a sweet spot. Also after reading another thread someone spoke of trying a blend from the 20s. What is the oldest blend you've smoked?
