Author: R.A. Hamman Jr.
Must analyses, yields, harvest dates, and winter injury of 32 vinifera and hybrid grape cultivars were evaluated at Colorado State University's Orchard Mesa Center over a 5-year period. The 27-year average heat unit accumulation (10C base) at this site was 3,284, with 163 frost free days (0C base). Vitis vinifera cultivars that were consistently productive, had excellent fruit quality, low incidence of winter injury, and generated very acceptable enological characteristics were 'White Riesling,' 'Chardonnay,' 'Muscat Blanc,' 'Limberger,' 'Cabernet Sauvignon,' 'Merlot' and 'Cabernet Franc' The best French hybrid cultivars evaluated were 'Seyval blanc,' 'Vidal blanc,' Chancellor' and 'Rougeon.'
