Van Williamson, winemaker and owner of Witching Stick Wines, brought a wine produced with Pinot vines that had been grafted onto Zinfandel rootstock. He said he likes to see about 2 pounds of fruit to each vine, but he saw something more like 20 pounds per vine in what he described as the big vintage of 2016. While Williamson said some of the debate on crop level and row density in California is overrated, he was clear that he never wants to see his vines hang that much fruit again. The vintner also mentioned he thought a wine produced with machine-harvested grapes was a successful trial. He said the labor situation could become so severe that it may compel growers, even in Anderson Valley, to use more mechanical harvesters.
