I've had the Corojo, Sumatra and Maduro versions and thought they were all decent to quite good. I'd probably rank them in that order in terms of my personal preference.A bit of a sales gimmick, but supposed to be better for the cigar than to be in cellophane. At least that's what the marketing department said. I do like the Corojo version.
Now smoking a Curivari Sun Grown Maduro with some espresso from Cameroon.
