Current and new trials Viticulture & Enology Research Priorities
Research priority #1: Cold hardiness and methods of protection Research priority #2: Quality improvement of fruit and wine Research ppyriority #3: Evaluation of winegrape varieties new to Ohio Research Objectives
To evaluate new winegrape cultivars and selections for their potential to be grown in Ohio and produce high quality wines ¾ Viticultural and enological performances
To predict best site-varietyyg matching in Ohio ¾ “Terroir” Varietyy@ Evaluation @ OSU Variety Evaluation Protocol Plant & train several varieties (Year 1-3)
Evaluate viticultural Evaluate enological performance performance (Year 4 – 8 or 10) (Year 4 – 8 or 10)
Identify top viticultural Identify top enological performance performance (Year 8 or 10) (Year 8 or 10)
Identify & recommend “best” performers (Year 8 or 10)
Identify & NOT recommend “t”f“worst” performers (Year 8 or 10) Completed Trials
Planted: 1995 – 1996 RdReds Whites Wooster, Kingsville, Ripley Cab franc Auxerrois 25 varieties planted: hybrids, and vinifera Chambourcin Bianca
We identified a dozen that Frontenac Chardonnay have potential to perform Limberger Pinot gris well in Ohio Noiret Traminette Performance results will Petit Verdot Valvin Muscat be presented at this conference New Germplasm Trials
8 trials since 2004
Variety, clone, and rootstock trials
Emphasis on high wine quality, disease resistance, and winter hardiness

To evaluate new winegrape cultivars and selections for their potential to be grown in Ohio and produce high quality wines ¾ Viticultural performance ¾ Enological performance
To predict best site-variety matching in Ohio ¾ “Terroir” GIS to Predict Site-Variety Matching
