Cenizo

Cenizo is the canonical example used in the botany chapter to illustrate the regional-instability problem in agave local names: a single name attaches to materially different plants in different states, and the mapping cannot be flattened into a one-name, one-species table.

In Durango. The dominant and well-attested use of "cenizo" is for Agave durangensis, the defining mezcal agave of the state of Durango. The name (from ceniza, "ash") refers to the pale, ash-gray waxy bloom on the leaves of mature plants. A. durangensis is a large-rosette species, partly cultivated and partly semi-wild, that anchors Durango's claim to a mezcal tradition distinct from the Oaxacan one. Cenizo plants in Durango mature in 12 to 18 years and produce piñas of 30 to 80 kg. Distillate profile: mineral, slightly herbaceous, with the distinctive savory and faintly smoky character that defines Durango mezcal at the category level.

In Sonora and Chihuahua. The same name "cenizo" is used regionally for other agave taxa. In Sonora the most common attachment is to local variants of A. angustifolia (the bacanora-base species), particularly forms with a marked grayish-waxy leaf surface that visually resemble the Durango cenizo. In Chihuahua the name is occasionally used for A. asperrima and other arid-zone agaves. In some Puebla contexts the name has been recorded for A. potatorum. The common thread is the leaf bloom; the underlying species varies by latitude, elevation, and local naming tradition.

Editorial guidance. Treat "cenizo" as a regional-instability name. When the producer is in Durango, default to A. durangensis. When the producer is in Sonora or Chihuahua, demand explicit species attribution before mapping the name to a taxon. The instability is not a failure of producer knowledge; it is a feature of how local agave names have evolved across a country with deep regional fragmentation in mezcal tradition. The botany chapter works through this and several adjacent cases (notably tobalá and espadín for the opposite pattern of name stability) in its discussion of how local names map to Linnaean species.
