Billionaire Stewart Resnick, owner of California citrus and pistachio farms and brands including Fiji Water, bought Sonoma Valley’s Landmark Vineyards as deals for premium-wine properties rebound. Resnick may double production of Landmark’s highly regarded chardonnay “over a period of time, consistent with quality,” he said in an Aug. 1 telephone interview, a day before completing the purchase of the 18-acre (7.3-hectare) property in Kenwood, California, about 55 miles (88 kilometers) north of San Francisco. It was Resnick’s second vineyard purchase in less than a year, and the price wasn’t disclosed.
