IN SITU Mezcalería

IN SITU Mezcalería opened in the city of Oaxaca in 2010, founded by Ulises Torrentera and Sandra Ortiz. The business operates as both a mezcaleria and a retailer, built on years of the founders traveling to visit palenques directly and taste through their production before selecting what to carry. The site describes the collection's origin in their own words: "Many roads traveled, palenques visited and mezcals tasted."

From that groundwork the founders created an in-house label, Tochtli, meant to gather the range of what they encountered on those trips rather than to represent a single palenque or region. This positions IN SITU as a curator of traditional mezcal drawn from multiple producers and villages across Oaxaca, rather than a single-origin producer itself, with selection driven by direct, hands-on relationships with the maestros mezcaleros behind each bottle.

The mezcaleria functions as a tasting destination in Oaxaca city as well as an e-commerce operation shipping within Mexico. The site does not publish specifics on individual agave species or named palenque partners for each product, so those details are not asserted here; what is documented is the founders' direct-visit sourcing model and the fifteen-plus years the business has operated in Oaxaca.
