Not sure if it was the power of suggestion, but I smoked a Joya de Nicaragua Antano 1970 last night, and noticed a minty taste on the finish. The mint was noticeable on the finish, especially through the nose when retrohaling. Not an artificial "cool" taste like peppermint, but a vegetal mint like a mint leaf.
There have been other times when I've tasted the flavor when smoking other cigars, names that unfortunately, don't come to mind.
