- The role of research and extension in supporting the expansion of the grape and wine industry in USA and in Michigan
- Impact of viticultural practices in improving fruit quality in cold-cool climate viticulture
Similar to other cold-cool climates regions of the World (Austria, Germany, new Zealand and north of France) wines produced in Michigan are aromatic and with distinctive varietal character.
However, the limiting and challenging weather impose great attention on selecting wine grape varieties and cultural practices. While market pricing and demand varieties by wineries may direct growers to plant specific varieties, it is important to carefully consider the varieties that are best suited for each specific sites. There are many factors, which must be considered in planting a new vineyard: crop control and canopy management pivotal for the production of grapes. Crop control is a vineyard practice that includes the adjustment of the vine to balance the amount of fruit with the growth of the vine.
Moreover, to ensure the production of high quality grapes, growers in the Midwest implement canopy management practices especially in vineyards seeking maximum wine quality. Canopy management is the practice that results in the modification of position and amount of leaves, shoot, and fruit in trellis system. Benefits canopy management are maximizing sunlight interception improving fruit quality, increasing air movement leading to faster drying time from rain and thus less disease pressure.
