Research Update: Grape Powdery Mildew Management

March 15, 2017|OWB Funded Research, Scientific Research, Viticulture + Enology|

Walt Mahaffee, USDA, and Brent Warneke, Oregon State University, are researching how to improve the efficiency of grape production by optimizing fungicide selection and timing to manage powdery mildew of grape berries. This research will determine the most effective fungicide application timing with relation to grape inflorescence development / phenological stage and how fungicide mobility [...]

Research Update: Integrative studies of vector-related field epidemiology for grapevine red blotch-associated virus

February 16, 2017|OWB Funded Research, Scientific Research, Viticulture + Enology|

Grapevine virus diseases are of serious concern for vineyard managers and winemakers in all Western production regions. Grapevine red blotch-associated virus (GRBaV) impacts grape berry quality. Growers and scientists alike have noticed a consistently lower °Brix at harvest of infected vines, resulting in removal of symptomatic vines from vineyards. What's more concerning is that GRBaV [...]

Research Update: Statewide Crop Load Project Continues Long-Term Research to Understand the Complex Yield-Quality Relationship

January 19, 2017|OWB Funded Research, Scientific Research, Viticulture + Enology|

The Statewide Crop Load Project is a long term industry-collaborative study that scientifically evaluates the impact of yield on wine quality across Oregon vineyards. The project focuses on Pinot noir, as a recent study in Oregon indicated that it is more commonly crop thinned to specific yield goals in an attempt to reach a higher fruit quality [...]

Research Update: Molecular and Biochemical Analysis of Phenolic Acid Decarboxylase from Brettanomyces Yeast Isolates

November 16, 2016|OWB Funded Research, Scientific Research|

Contamination by Brettanomyces is a major contributor to spoilage of finished wine. One mechanism of spoilage is through metabolism of grape-derived compounds, hydroxycinnamic acids (HCAs). Brettanomyces yeast converts these compounds into volatile products responsible for off-aromas and flavors, notably 4-vinyl phenol (4-VP) and 4-ethyl phenol (4-EP). This “Brett taint” is often described as horse blanket, [...]

Research Update: Impact of Pre-Fermentation Cold Soak Conditions on Microbial Populations and Consequences for Wine Aroma

October 19, 2016|OWB Funded Research, Scientific Research, Viticulture + Enology|

Wine aroma is one of the most important components of wine quality and can be impacted by grape variety, viticultural practices and winemaking procedures. One particular practice that is employed during Pinot noir production to impact wine aroma is cold soaking. In this process, grapes are held at cold temperatures to prevent growth of Saccharomyces [...]

Pest Management Strategic Plan for Wine Grapes in Oregon

July 18, 2016|OWB Funded Research, Scientific Research, Viticulture + Enology|

In a proactive effort to identify pest management priorities and lay a foundation for future strategies, wine grape growers, commodity group representatives, pest control advisors, regulators, university specialists, and other technical experts from Oregon formed a work group and assembled a Pest Management Strategic Plan for Wine Grapes in Oregon, which was funded through an OWB research [...]
