Silver Oak Cellars, a winery in Oakville, Calif., Oct. 25, 2018. Owner David Duncan expects the main challenge facing Silver Oak over the next decade is not marketing, or finding customers, but finding enough high-quality raw materials to sate the looming boom in demand; he recently bought the cooperage where his barrels are sourced.
