Arroyo Seco

Arroyo Seco is an American Viticultural Area (AVA) in Monterey County, on the eastern side of California’s Salinas Valley near Greenfield. Its name refers to the generally dry Arroyo Seco watercourse, which descends from the Santa Lucia Mountains into the valley. Although the vineyards are inland, cooling marine air moving in from Monterey Bay through the valley is a defining influence. Warm, bright days give way to cool nights and frequent morning fog, extending the growing season and helping grapes retain acidity.

Soils are largely youthful, deep alluvial deposits left by the Arroyo Seco: sand, loam, gravel and rounded stones washed down from the mountains. They are generally free-draining and often stony. With appropriate vineyard management, this can restrain vine vigour, while making careful irrigation important. The combination of sunshine, cool air and drainage suits grapes that benefit from gradual flavour development, though temperature and wind vary noticeably across the AVA.

Chardonnay is the region’s principal calling card, made in both bright, citrus-led styles and riper, barrel-influenced versions. Pinot Noir can enjoy a long ripening period in the coolest sites, producing wines that are usually light to medium-bodied and red-fruited. Riesling and Sauvignon Blanc may show lively acidity with floral or herbal notes. Warmer sites also ripen Cabernet Sauvignon, Syrah, Grenache and Tempranillo; these reds often combine ripe fruit with more freshness than counterparts from California’s hotter inland areas.

An AVA is a geographical origin, not a quality classification: it does not prescribe varieties, yields or maturation methods. For a US wine labelled with Arroyo Seco as its appellation, at least 85% of the grapes must generally come from the AVA. Producers working with fruit from the area include Ventana, J. Lohr, Wente, Muirwood, Kendall-Jackson, Scott Family Estate and Joullian. Many Chardonnays are appealing when young, while more concentrated examples and serious reds can reward several years in bottle.
