San Antonio Valley

Sauvignon Blanc that is intensely citrussy and saline; Pinot Noir that is red-fruited and savoury; Syrah that is peppery and medium-bodied.
About San Antonio Valley
San Antonio lies close to the Pacific south of Valparaíso, and it was planted only from the late 1990s — the water had to be piped in before viticulture was possible at all.
The Humboldt Current runs cold along this coast, and the fog and wind it generates make San Antonio and its Leyda sub-valley among the coolest sites in Chile.
Sauvignon Blanc here is sharp, saline and herbal; the Pinot Noir and cool-climate Syrah are among Chile’s best.

Vintage variation
Vintage matters somewhat
A dependable climate with occasional difficult years. Most vintages are broadly similar; the exceptions are the ones worth knowing about.
- Maritime influence. Nearby water lengthens the growing season and brings cloud and rain with it. Ripening is slower and less certain, and the spread between years is wider.
- Growing-season temperature. Cool. There is little heat to spare, so a cloudy summer shows in the finished wine.
Derived from the climate above, not from anyone’s view of particular years. Why there are no vintage scores here.
These are influences on how a wine turns out, not determinants of it. Picking date, yield, vine age and every winemaking decision sit between the climate and the glass.
