From the winery:
Arroyo Seco is widely regarded as one of the best places in California to grow Chardonnay. Riva Ranch is the name of the Wente family’s vineyard in Arroyo Seco, where we have been growing Chardonnay since the 1960’s. Wente Vineyards was the first California winery to produce a wine labeled as Chardonnay in 1936. Today, many of the great Chardonnay vineyards in California are planted with the Wente Clone. Riva Ranch is presently planted to three Dijon clones and two Wente clones: clone 2A which had been originally selected for its intense varietal character and low yield, and clone 4, a second generation Wente clone. The cool growing season and the deep gravelly soil ripen the Chardonnay perfectly, creating a natural balance of sugar and acidity.
