WineEast Grapegrowing Establishing a Noiret Vineyard Vine training program, spacing and root system impact yield and fruit composition By Justine E. Vanden Heuvel N oiret is an interspecific red hybrid wine grape that was released by Cornell University in 2006. The original cultivar description (Reisch et al. 2006) describes the growth as semi-upright to semi-trailing and reports that Noiret is smaller than both Concord and GR7 with respect to yield and vine size. However, anecdotal reports from Finger Lakes growers suggest that Noiret vines can be vegetative and unruly. Many growers are interested in planting this cultivar, but there is little research to provide guidance about the appropriate viticultural practices for Noiret. Should the vines be own-rooted or grafted? What training system should be employed? How close or far apart should the vines be spaced? The objective of this field study was to investigate the impact of training system, vine spacing and rootstock on vine growth, yield components, fruit composition and consumer preference for Noiret wines produced from a young vineyard. Materials and methods Vineyard site and experimental design. The planting was established in 2007 at the New York State Agricultural Experiment Station in Geneva, N.Y., in a block with deep, well-drained Honeoye fine silt loam. Rows were spaced 9 feet apart and oriented north-south. The experiment was replicated five times. The treatments were training system, as the main plot high-wire cordon (HWC) vs. low cordon with vertical shoot positioning (LVSP), and vine spacing as the subplot (6 feet vs. 8 feet), with root system (own-rooted vs. grafted on 101-14 Mgt) randomized among the sub-plots. Panels were 24 feet Wine East HIGHLIGHTS • New York field study about the recently introduced red hybrid A wine grape Noiret investigated the impact that planting and training decisions have on grape and wine production. • igh-wire cordon was compared to low cordon with vertical H shoot positioning; vine spacing was 6 feet vs. 8 feet, and root systems were own-rooted vs. grafted on 101-14 Mgt rootstock. • arly results suggest that the inherent vigor and downward E growth habit of Noiret make it unsuitable for a VSP trellis system in the early years of the vineyard.
