I am going to resurrect this thread. I am not really a cigar smoker, maybe a couple per year, but I do like the candelas I've tried. I like the lighter flavor of the smoke. My favourite were a couple Camacho candelas... I learned they had last made them in 2017, I think, so they were sitting in the shop humidor for about 5 years. I also liked the Espinosa Wasabi, though I found it to be too spicy for my tastes.
I don't know much about anything, but in addition to a vegetal flavor (it tastes more like the weeds you weedwhack on the side of your house than grass to me) I would get almost vanilla or honey notes. Maybe that was a casing, but my impression is that the difference between a candela wrapper and a regular cigar is the same kind of difference between green tea and black tea.
All of that to say that I think candela wrappers definitely have their place and there is some method to make them taste good, but I think the comparison to the "real" cigar experience hurts their rep. Like it was mentioned, back in the day they were super popular in the US.
TL;DR don't be mean to candelas and give them a chance because they deserve love, too.
