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 granitic-clay coastal vineyards.

Blackberry, rosemary, sage and flowers; balanced, elegant and structured with a long fruit finish.

Herb-roasted lamb, grilled mushrooms, pork or hard cheese.

The range's most aromatic and savoury red, for buyers who value varietal character over simple fruit sweetness.
