Hexagone Café

Hexagone Café is a Paris-based specialty roaster and café founded by four partners — David Lahoz, Sébastien Racineux, Chung-Leng Tran, and Stéphane Cataldi — on the Left Bank in the 14th arrondissement. From its address at 121 rue du Château, it operates as both a retail café and a roasting label, with production handled at a dedicated roastery in Louargat, in the Côtes d'Armor department of Brittany. The dual footprint — Paris café, Breton roastery — gives the operation an unusual geographic split for a French specialty brand.

When the project launched around 2015, Sprudge described it as "an embrace of specialty coffee culture," arriving at a moment when Paris's third-wave scene was still thin on the ground. The founding team set out to make specialty coffee both expert and accessible — a position reflected in the café's reportedly chill, unpretentious atmosphere documented by early visitors and local press.

Hexagone sources only coffees scoring 84 points or higher on the SCA scale — a threshold they peg at less than 1% of global production. Green beans are purchased either through direct relationships with producers or via carefully vetted importers. Roasting happens to order for wholesale and professional clients, in small batches at the Louargat facility, with freshness as an explicit priority; the roastery's blog notes that properly degassed coffee in a sealed bag retains its organoleptic qualities for several months, after which espresso loses body. Aromatic clarity is the stated house benchmark, applied across both espresso and filter offerings. Extraction training and hands-on dialing-in support are built into the brand as a distinct service rather than a secondary offering.
