Clase Azul Tequila Mezcal San Luis (750 ml)

When Arturo Lomelí launched Clase Azul in 1997 at $100 a bottle — a moment when the category ceiling sat at roughly $18 — he was not refining tequila convention but deliberately rupturing it. That same transgressive logic governs the San Luis Potosí mezcal expression: a spirit that sits outside the Tequila DO entirely, produced from agave native to San Luis Potosí rather than the Jalisco Highlands that define the core range.

The Clase Azul distillery anchor is Los Altos de Jalisco — red volcanic, mineral-rich soils at high altitude near Arandas — where cool nights and elevated terrain push Tequilana Weber Blue Agave to 6–9+ years of maturity, yielding oversized, sugar-dense piñas. The San Luis expression draws on a different agave-growing tradition entirely, shifting both raw material and regional terroir outside Clase Azul's established Jalisco identity.

Production follows the brand's signature protocol: piñas slow-roasted in traditional masonry brick ovens for a minimum of 72 hours, fermented with a patented proprietary yeast strain, distilled twice, and subjected to triple filtration — the process that defines the house's characteristically full-bodied, low-heat profile and that purists argue trades raw agave expressiveness for textural luxury. Bottled at 40% ABV. The hand-painted ceramic decanter is produced by Mazahua artisans in Santa María Canchesda, each vessel requiring approximately two weeks to complete.

The special feature here is categorical: this is not tequila. By stepping into mezcal from San Luis Potosí, Clase Azul breaks from its own Jalisco DO identity — the only expression in the core range to do so — making it the brand's most explicit statement that the ceramic vessel and production philosophy travel beyond the blue agave monoculture.
