I did not find a resemblance between Samsun Maden and Big Gem. The Samsun Maden is distinctly "Turkish," mildly aromatic and generally mild. The Big Gem I found to be clearly related to other flue-cure varieties, though with a huge, thick leaf. I produced some green candela cigar wrapper from Big Gem in my Cozy Can. These were thick, tough, and almost flavorless--as would be expected for candela. The air-cured and kilned Big Gem offered little to distinguish it from many of the other flue-cure varieties that I've grown, other than a tendency to produce a somewhat more rank growth.
