Buna 42

Buna — listed in some directories as Buna 42 — is a specialty coffee roaster and espresso bar based in Mexico City whose conservation mission is woven into the business model rather than appended as branding. Founding date and founder names are not disclosed on the company's own channels, but The Coffee Vine has cited it as one of Mexico City's first "next-level specialty coffee bars," placing it among the wave of CDMX roasters who helped shift the capital's café culture toward third-wave standards.

As Daily Coffee News reported in April 2021, Buna evolved beyond its origins as a café to develop what the publication called "a unique vision for protecting Mexican ecosystems." The company's current direct-to-consumer operation — a Shopify storefront with a subscription tier and a wholesale channel aimed at local businesses — reflects significant growth from a single espresso bar. Their roastery and community space, called La Tostadora, serves as a venue for workshops, tastings, and talks, positioning the brand as a node in Mexico City's broader specialty coffee ecosystem.

Buna's retail catalog centers on Mexican-origin coffees marketed under the label "café rico," a phrase that doubles as a quality claim and a nod to the brand's conservation framing — rico evoking both flavor richness and biodiversity. The company applies the same sourcing logic to honey and cacao, which it sells alongside coffee under a "del campo a tu mesa" (field to table) positioning. The model implies direct or near-direct relationships with smallholder producers working in biodiverse Mexican growing regions, though specific varietal, processing, or terroir details are not foregrounded on the current homepage.
