Mayu operates in Chile's Elqui Valley, a region in Coquimbo known for its cool-climate precision and mineral-driven wines. The winery's portfolio centers on two distinct expressions of the valley's terroir: a Reserva Syrah that channels the region's capacity for structured, age-worthy reds, and a Don Mauro Vineyard Gran Reserva Carménère that showcases the indigenous Chilean variety's dark fruit and spice. A Pedro Ximenez rounds out the range, offering a fortified counterpoint. Wine Advocate, Decanter, Wine Spectator, Wine Enthusiast, and Falstaff have all assessed Mayu's releases, with the Reserva Syrah earning particular recognition among prestige critics. The winery's focus remains on varietal expression within Elqui Valley's distinctive growing conditions.
