Viticulture

Colorado is home to approximately 800 acres of wine grapes. About 85 % of the acreage is in Mesa and Delta County accounting on average for 95 % of the state’s grape production. The dry and hot climate during the growing season provides ideal conditions to produce high quality grapes and wines. However, erratic and extreme cold temperature events during late fall and the dormant season lead to severe vine and crop damage and limit the area where vines can be grown.

Cold Hardiness Research

One research focus of the Viticulture Program is on understanding, avoiding, and mitigating cold temperature injury. Other research areas include cover crops and irrigation management, cultivar and rootstock selection, evaluation of new cultivars, and alternative management practices to protect the graft union from cold injury.
