Guillaume Langloy founded Loutsa Torréfacteur in 2018 in Lyon, bringing a distinctive approach to specialty roasting built around a color coded aromatic palette that guides drinkers through flavor profiles. Working with a Diedrich roaster, the team develops profiles that balance clarity and depth, making specialty coffee approachable for newcomers and rewarding for seasoned enthusiasts. What began as a single Lyon operation has grown rapidly to encompass five locations in Lyon, four in Paris, and one in Saint Etienne. This expansion reflects both the quality of their roasting and their talent for creating welcoming cafe spaces. Loutsa also hosts workshops and tasting sessions, deepening the connection between their roastery work and the people who enjoy it.
