Calcu works the coastal side of Colchagua's Marchigüe sector, where Pacific breezes moderate warm days and granitic clay soils naturally limit yields. Its gravity-fed winery uses geothermal energy, cutting gas and electricity use while handling fruit gently.

Marchigüe

Small-block selection from the Pacific-influenced side of Colchagua, made in a gravity-fed geothermal winery.

Pink grapefruit and mango; Sauvignon brings freshness while Semillón adds mid-palate complexity and a long, juicy finish.

Ceviche, grilled prawns, salads or sushi.

A familiar Bordeaux pairing recast through coastal Chile, with more texture than straight Sauvignon and more freshness than warm-climate Semillón.
