The 2006 vintage marks the twentieth year of J. Lohr's production of Riverstone Chardonnay from their vineyards in the Arroyo Seco region of Monterey County. Each year, starting in 1995, they have experimented with and have incorporated higher percentages of traditional Burgundian production techniques into Riverstone, until the desired complexity and end-results were achieved.

The result is a complex and nuanced Chardonnay with an abundance of Arroyo Seco fruit, with subtle barrel fermentation and malolactic character. The vines are grown primarily on Elder loam soils underlain by "riverstones" deposited over thousands of years from the Arroyo Seco river, allowing a four-foot rooting zone that keeps the vines' vegetative growth and fruit in balance. Additionally, the cool climate and winds of the Salinas Valley extend the growing season and retain the natural grape acids and intense varietal character of the Chardonnay.
