  A Review of Cold Climate Grape Cultivars

  There has been interest in growing grapes in the upper Midwest and other cold climate regions of North America. One of the problems growers face in these regions is selecting cultivars (cultivated varieties) that will withstand severe winters, mature in short growing seasons, and be productive. As grape acreage increases in cold climate regions, too often cultivar selections are being made based upon testimonial or anecdotal information. With the high costs of vineyard establishment there is an increasing need for a standard reference to assist growers in selecting best adapted cultivars. This publication can be viewed via a PDF reader and by using the bookmark function, you will be introduced to 74 varieties. Previously available in CD format and known as known as EDC 383.
