I have made candela accidentally, simply by progressing a flue-cure run from yellowing to leaf wilt before a particular variety had actually yellowed. It was some years ago. My very first flue-cure run. I assume that I primed the leaf in question when it looked somewhat mature. The aroma from the chamber at that point in the run smelled like cooking asparagus (a sure sign that you've messed up the flue-curing), and the leaf came out a lovely, consistent, light green candela, at the end of the run. As a cigar wrapper, it tasted like most commercial candela. As filler, it was pretty awful.
I sent some to the late
@johnlee1933, who failed to see my hand-written note in the parcel. He PM'd me soon after receiving it, saying, with apologies, that it was just horrible tobacco. Once he rummaged through the discarded shipping materials--at my direction, and found my note explaining that it was for wrapper, he subsequently reported that it made an okay wrapper, but that he had never liked candela cigars anyway.
