identify and remove MOG By Thomas Ulrich
Conn Creek Winery uses optical sorting technology for its Anthology project.
Highlights
• Optical sorters got significant tryouts in California during the 2010 harvest.
• Using electronic vision, they can remove more MOG than hand sorting with a pace three times quicker and a cost of about $140 per ton.
• Optical sorters require careful calibration, but winemakers at Clos Pegase and Gundlach Bundschu were pleased with their results.
