Strength
Strength refers to nicotine concentration and the resulting physiological effect. A "strong" cigar produces measurable nicotine intake; smokers experience this as a slight buzz, mild dizziness on prolonged smoking, or simply increased focus. Strength is primarily a function of leaf priming (ligero is highest in nicotine) and fermentation degree.
Strength categories: Mild (< 1.0% nicotine wrapper average), Mild-Medium (1.0-1.5%), Medium (1.5-2.0%), Medium-Full (2.0-2.5%), Full (2.5-3.5%), Strong (> 3.5%). Most premium cigars sit in the Medium to Full range.
Body
Body refers to the perceived weight and density of the smoke on the palate — how much "presence" each draw produces. A full-bodied cigar feels substantial, almost chewy on the tongue; a light-bodied cigar feels delicate. Body is primarily a function of filler density, leaf concentration, and combustion temperature.
A cigar can be Mild in strength but Medium-Full in body (e.g., Davidoff Grand Cru Robusto: low nicotine, dense smoke). The opposite combination is also common in modern Nicaraguan production.
Flavor
Flavor refers to the specific taste compounds the smoker can identify: cedar, leather, cocoa, coffee, dried fruit, mineral, espresso, vanilla, etc. Flavor is largely independent of strength and body — a Mild light-bodied cigar can deliver complex, distinctive flavor (a properly-aged Connecticut shade Hemingway), while a Full-bodied strong cigar can be flavor-flat (over-fermented oscuro that delivers nicotine but no developed taste compounds).
How They Combine
The three-axis taxonomy explains why cigars described identically in marketing produce such different experiences. A "Strong, Bold, Maduro" cigar from a Nicaraguan boutique is not the same as a "Strong, Bold, Maduro" cigar from a mass-market US line — the strength may match, but body density, combustion temperature, and flavor architecture differ markedly.
The KCS rubric scores Flavor at 35 points (the largest single dimension), Intensity at 10 (a proxy for the integration of strength and body), and Construction at 20. The three-axis vocabulary is what allows the rubric to distribute points meaningfully.
