Worst free cigar ever? Well, I completed a 'dog rocket challenge' some years ago where I had to smoke (and review) 16 dog rockets. I don't remember all the names, and half of them were unbanded. But I do remember Occidental Reserve something. And it was awful. A BOTL gave me a Tusker as a joke once that was pretty terrible. Tusker is a house brand of the hated 'T' company.
I also accepted a challenge by a Puros Indios fan who didn't believe I could recognize any Reyes cigar just based on flavor and aroma. He sent me 10 cigars, 5 of which were Reyes cigars and 5 that were not.
I guessed all 5 Reyes cigars correctly. The only one I got wrong was a CAO something that tasted like a Rolando Reyes cigar (moldy hay, grass, chemical aftertaste).
