Zero-Zero Wine
Historic valley viticulture revived. Carolina Alvarado and Arturo Herrera craft additive-free wines from dry-fammed País and Sauvignon Blanc, fermented in cow hide and bamboo.
Carolina Alvarado and Arturo Herrera continue a 400+ year winemaking legacy in Chile's oldest wine valley.
Working together as a team and as part of the Sur Natural association, Carolina and Arturo have established themselves as guardians of the Marga Marga Valley's historic viticultural heritage. They also operate as a small cooperative, supporting local growers in maintaining traditional dry-farming practices.
Carolina Alvarado
Oversees the dry-farmed vineyards and traditional methods. Carolina works closely with local farming families to preserve the historic bush vines of the valley, ensuring sustainable practices and grape quality.
Arturo Herrera
Manages the zero-zero cellar practices and traditional fermentation methods. Arturo specializes in the ancient techniques of cow hide fermentation and bamboo destemming that define their wines.
Nothing added, nothing taken away. Ancient techniques for pure expression.
Cow Hide Fermentation
Red wines ferment traditionally in cow hides (cueros), an ancestral method that provides natural temperature control and gentle extraction. This pre-Columbian technique creates wines of unique texture and earthy complexity.
Bamboo Destemming
Hand-destemming using traditional bamboo implements ensures gentle handling of the fruit. This labor-intensive process preserves berry integrity and avoids the harsh tannins of mechanical processing.
Zero Additives
Strict zero-zero philosophy: no added sulfur, no commercial yeasts, no enzymes, no corrections. Just grapes, time, and tradition. The wine speaks entirely of the vineyard and the vintage.
First planted in 1586. Dry-farmed heritage in Chile's oldest wine valley.
Marga Marga Valley
The historic heart of Chilean viticulture, where the first vines were planted in 1586. This coastal valley near Valparaíso benefits from Pacific breezes and alluvial soils, creating wines of elegance and freshness.
Dry-Farmed Heritage
Unirrigated bush vines of País and Sauvignon Blanc, some over a century old. These vines have never known chemicals or modern irrigation, surviving on winter rains and morning fogs from the Pacific.
Cooperative Model
Beyond their own estate, Carolina and Arturo work as a small cooperative, supporting local growers in the valley. They provide expertise and ensure fair prices for grapes farmed traditionally, helping preserve the region's viticultural heritage.
