Of the four wineries below, which was the first to plant chardonnay in the Napa Valley?

D.

Stony Hill, a small cult winery on Napa Valley’s Spring Mountain, planted chardonnay in 1948. At that time, there were only 200 acres of chardonnay in the whole state (compared to the nearly 98,000 acres planted today.) Schramsberg Vineyards planted chardonnay for its famous sparkling wines in 1965. The Robert Mondavi Winery’s first chardonnay was planted in 1970. And Kendall Jackson, which is not located in the Napa Valley, made its first chardonnay in 1982 and now makes some 2 ½ million cases of chardonnay annually.
