Extra Añejo

Extra añejo ("extra aged") is the heaviest oak tier of tequila and mezcal. Under NOM-006-SCFI-2012A regulatory-standard NOM is a federal Mexican product norm. Unlike facility NOMs (4-digit identifiers of specific distilleries), a standard NOM defines the rules for an entire category of product: which raw materials are permitted, where the product may be made, how it must be processed, and how the bottle must be labeled. Standard NOMs are written as "NOM-XXX-SCFI-YYYY" where XXX is the standard number and YYYY is the year. NOM-006-SCFI-2012 (Tequila). The official Mexican standard governing every aspect of Tequila production: which agave species may be used (only Agave tequilana Weber var. azul), which states and municipalities qualify, how the spirit must be distilled, what additives are permitted (up to 1% by volume even in '100% agave' bottles), and how the bottle must be labeled. Enforced by the Consejo Regulador del Tequila (CRT). a tequila extra añejo has spent more than three years in oak barrels of no more than 600 litres in capacity, with no upper bound; NOM-070-SCFI-2016A regulatory-standard NOM is a federal Mexican product norm. Unlike facility NOMs (4-digit identifiers of specific distilleries), a standard NOM defines the rules for an entire category of product: which raw materials are permitted, where the product may be made, how it must be processed, and how the bottle must be labeled. Standard NOMs are written as "NOM-XXX-SCFI-YYYY" where XXX is the standard number and YYYY is the year. NOM-070-SCFI-2016 (Mezcal). The official Mexican standard for mezcal production. Defines three production tiers (Mezcal Industrial, Mezcal Artesanal, Mezcal Ancestral) with specific equipment and method requirements for each, lists the permitted agave species and states, and governs labeling. Enforced by the Consejo Regulador del Mezcal (CRM). applies the same minimum to mezcal extra añejo. The category was introduced for tequila in a 2006 revision of NOM-006, codifying what producers had been doing informally for some time and creating a market segment that did not previously exist on the label.

Three years and beyond is the window in which the spirit is reshaped substantially by the cask. Color deepens to mahogany, vanilla and caramel become structural rather than accent notes, and the agave signature can recede into the background. In a poorly judged extra añejo the agave disappears entirely and the spirit drinks closer to a bourbon or a cognac than to a tequila. In a well-judged extra añejo (typically aged in larger casks or in cooler cellars to slow extraction) the agave's vegetal-mineral structure persists as a low note under the oak.

The category overlaps with the cristalino practice: many cristalinos are extra añejos that have been carbon-filtered to strip the color. Triple distillation also appears more often at this tier, both for chemical smoothness and for marketing reasons. The distillation chapter covers the aging chemistry in full.
