Calle 23

At a glance

Calle 23 is a craft tequila brand founded in 2007 by Sophie Decobecq, a French biochemist who still owns and runs it independently. The brand is currently produced under NOM 1545NOM (Norma Oficial Mexicana) is the Mexican federal product-standard system. On a tequila bottle the NOM number is the unique identifier of the distillery facility where the tequila was made — every drop in the bottle came from a plant operating under that NOM. Different brands made at the same NOM share a distillery. NOM 1545: Hacienda Capellanía, S.A. de C.V. (San José de Gracia, Jalisco, Los Altos). Calle 23's current production facility; founder Sophie Decobecq. in San José de Gracia, in the Los Altos (highlands) of Jalisco.

Calle 23 is worth knowing for two reasons that have nothing to do with celebrity or luxury packaging. First, it is one of the clearest examples of a woman-founded, scientist-led craft brand in a category dominated by large houses and famous faces. Second, its production history is a useful teaching case in how to read a tequila label honestly, because the brand has moved between distilleries over its life and the bottle's facility code has changed with it.

A biochemist, not a brand manager

Most tequila origin stories start with land, family, or fame. Calle 23 starts with a laboratory. Decobecq trained as a biochemist in France and came to the craft through the science of fermentation rather than through an inherited distillery. That background is not decoration; it is the brand's signature.

The defining choice is yeast selection. Rather than ferment every expression with one house strain, Decobecq works with different cultivated yeast strains chosen for what each one contributes, so that the Blanco, Reposado, and Añejo are not simply the same distillate at different ages but expressions built from different fermentation profiles. This is the kind of decision a fermentation scientist makes and a marketing department rarely thinks to. It is the reason Calle 23 reads, to people who follow tequila closely, as a craft brand with a point of view rather than a label looking for a story.

NOM 1545, and why the number has changed

Every certified tequila bottle carries a four-digit NOM that identifies the distillery facility where the tequila was made, not the brand that sells it. Calle 23 is currently produced under NOM 1545NOM (Norma Oficial Mexicana) is the Mexican federal product-standard system. On a tequila bottle the NOM number is the unique identifier of the distillery facility where the tequila was made — every drop in the bottle came from a plant operating under that NOM. Different brands made at the same NOM share a distillery. NOM 1545: Hacienda Capellanía, S.A. de C.V. (San José de Gracia, Jalisco, Los Altos). Calle 23's current production facility; founder Sophie Decobecq., a facility in San José de Gracia in the highlands.

Here is the literacy point that makes Calle 23 genuinely instructive. Over its life the brand has appeared under more than one NOM, previously 1433 and 1529, as Decobecq moved contract production between facilities. This is not a scandal and it is not hidden: a brand that contracts its production rather than owning its own distillery can and sometimes does change where it is made, and the NOM on the label moves with it. A brand that owns and operates a single distillery, by contrast, keeps the same NOM for its entire life. Neither model is inherently better, but knowing the difference is what lets a reader interpret a label rather than just trust it. When you see the same brand under different NOMs across vintages, you are reading the history of where it was made.

The agave is highland Agave tequilana Weber azul, and the house leans on traditional and craft methods rather than the most industrial extraction technology. There is no evidence the brand uses a diffuser, the extraction machine that enthusiasts treat as a transparency concern, which is consistent with its artesanal positioning.

What is in the range

The core line is Blanco, Reposado, and Añejo, each fermented with its own chosen yeast. Alongside them sits Criollo Blanco, a higher-proof bottling aimed at drinkers who want the spirit closer to still strength, where more of the fermentation character survives the trip to the glass. The through-line across all four is the same: the flavour decisions are made upstream, at fermentation, rather than corrected downstream with additives or smoothed away by ageing alone.

Calle 23 is priced and positioned as an accessible craft pour rather than a luxury or collector bottle. That accessibility is part of the editorial interest: it is a counterexample to the assumption that scientific seriousness and small-batch intent must come at a luxury price. Where the celebrity model sells a name and the luxury model sells a decanter, Calle 23 sells a fermentation decision at a working drinker's price.

The additive-free positioning

Calle 23 is marketed as additive-free, meaning the brand says it adds none of the colouring, sweetener, oak extract, or glycerin that tequila rules permit in small undisclosed amounts.

Tequila's rules (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).) do not force any of this onto the label, since they permit small undisclosed additions, which is exactly why a brand's stated additive-free stance is a positioning claim a reader should weigh rather than a guarantee printed on the bottle.

Where Calle 23 sits

Calle 23 is the craft-and-science counterpoint to the brands that dominate tequila's headlines. It is founder-owned rather than multinational-absorbed, scientist-led rather than celebrity-fronted, contract-produced with an openly changing NOM rather than marketed as a single mythologised estate, and priced for drinking rather than for display. Reading it against a celebrity-founded brand like Casamigos on one side and a single-estate, additive-transparent house like Fortaleza or Tequila Ocho on the other is the most useful exercise: it occupies a distinct corner of the map, where the most interesting decision is made by a biochemist at the fermentation tank.
