Francis Darroze grew up working at his family's two-star Michelin restaurant in the Bas-Armagnac region — his father Jean Darroze was the chef known as 'King Jean' of Landes gastronomy. From the age of 15, Francis accompanied his father on visits to local Armagnac producers in search of quality bottles for the restaurant cellar. By 1974, after years of sommelier-side sourcing experience, he set up Darroze in Roquefort as a producer-trader specialising in single-vintage, single-estate, cask-strength Bas-Armagnac — a deliberate break from the prevailing model of large-house multi-estate blending.
Bas-Armagnac is the south-western sub-appellation of the broader Armagnac AOC and is recognised as the source of the most cellar-worthy expressions of the spirit. Darroze sources finished spirit from approximately 30 small Bas-Armagnac estates and ages each separately under their own estate name — Domaine de Bellair, Domaine de Cravanceres, Domaine de Gaube, Domaine de la Gardenne, Domaine de Piheron, Domaine de la Poste — preserving each estate's distinctive character through extended barrel ageing in Roquefort and Labastide d'Armagnac. The bottlings are cask-strength (typically 40–50% ABV) and unfiltered, releasing vintage spirit from the cellars.
The Darroze range is organised around two principles: single-vintage estate releases (each labelled with the source estate and the year of distillation, ranging from the late 1940s to recent vintages) and the Grands Assemblages blends (multi-estate blends matured for specified periods — 12, 20, 30, 40 years). Marc Darroze, Francis's son, joined in 1996 as a trained oenologist and now leads the business. The current cellar holds a deep stock of older vintages, with releases of 60-year-old and older Armagnacs appearing periodically in the catalogue.
