Dayton, Ore. -- Northwest wineries are aiming for cleaner sorts of their incoming fruit this year, with sophisticated equipment designed to weed out material other than grapes (MOG), from greenery to grubs.While its grapes typically arrive at the winery in good shape, relatively free from material thanks to careful hand harvesting, 15,000-case Domaine Serene in Dayton, Ore., employs a “bug sucker” to remove lighter material that might otherwise cling to grapes prior to crush.
