Construction - How well is the cigar made? How does it feel to the touch? With a firm, but soft grip feel it from end to end. Does it feel consistent all the way through? Are there any hard or soft spots? A cigar that is too hard, too soft, or inconsistent will not draw properly.
Condition - Cigars should be well conditioned before smoking. Cigars should be aged for several months to several years at the proper humidity (70% RH) and temperature (70° F). A dry cigar will burn hot, fast and can taste harsh. A damp cigar will be hard to light and can be hard to draw.
Causality (cause and effect) - How does the cigar taste? How does the cigar make you feel? Does the cigar build in taste, flavor and complexity as it burns? Or is it the same all the way through? Do you feel relaxed and calm after finishing it?
