Napa Valley,CA—On the heels of the Napa Valley Vintners’ eighth trade mission to China, Wines & Vines talked with Marc Cohen, owner of 1,000-cases Howell at the Moon Winery, Angwin, about his successful penetration of the desirable Chinese market. It was, he said, a slow process. You may remember that in 2006, Wines & Vines published a six-part series (“The Start-up Winery” by Jane Firstenfeld), detailing Cohen’s laborious creation of the winery. In late 2009, we documented its successful switch to selling direct to retailers in New York and New Jersey.
