Oregon ‘Pinot noir’ grape anthocyanin enhancement by early leaf removal

Creator:: Lee, Jungmin and Skinkis, Patricia A.
Abstract:: Complete cluster zone leaf removal of 'Pinot noir' was initiated at three separate pre-veraison growth stages (bloom, grain-pea size, and bunch closure) and maintained leaf free until harvest, for four growing seasons (2008-2011). Fruit anthocyanin composition was examined at harvest for the last two vintages (2010 and 2011) and compared...

Determining the Impacts of Dormant Pruning Methods and Nitrogen Fertilization on Vitis vinifera 'Pinot noir' Bud Fruitfulness and Yield

Creator:: Ulmer, Miranda R.
Abstract:: The majority of grapes grown in Oregon are produced in Western Oregon’s Willamette Valley, where two-thirds of the acreage is planted to Pinot noir. The production of Pinot noir in the Willamette Valley comes at a high cost, and growers are seeking ways to increase profits while maintaining quality fruit...

Development of volatile composition and C₁₃-norisoprenoid precursors in Pinot noir grape, Development of volatile composition and C13-norisoprenoid precursors in Pinot noir grape

Creator:: Yuan, Fang
Abstract:: This study first investigated the developmental changes in the volatile composition and carotenoids of Pinot noir grapes. Grape berries were sampled every week from pea size to harvest during the 2011 and 2012 season. Carotenoids and organic acids were analyzed by HPLC. Volatile compounds were extracted from crushed berries using...

Volatile composition of Pinot Noir grapes and wines under different viticultural practices in western Oregon

Creator:: Feng, Hui
Abstract:: High vegetative growth of Pinot Noir vine is a common problem in most vineyards of Oregon's Willamette Valley, where sunlight exposure and heat accumulation are limited. Consequently, growers in this region commonly use vineyard management strategies to regulate vine vigor and improve grape and wine quality. Wine quality is greatly...

Sensory and chemical analysis of 1997 Oregon Pinot noir enzyme treated wines

Creator:: Goldberg, Naomi
Abstract:: Pinot noir has a reputation for lower color stability than other red wine varieties. Because it has relatively low anthocyanin and phenolic content and lacks acylated anthocyanin pigments compared to other red vinifera varieties, color extraction and stability are particularly important. Varying the processing during fermentation of red wine can...

Grape and Wine Aroma Influenced by Vine Nutrient Status, Vigor and Crop Levels in Oregon Pinot Noir

Creator:: Yuan, Fang
Abstract:: Wine volatile composition is one of the most important constitutes of wine quality, and it is greatly influenced by number of factors. The studies herein were conducted to evaluate the grape and wine aroma affected by different vine nutrient status, vigor and crop levels of Oregon Pinot noir. In the...

Spatiotemporal Phytohormone Distributions in Developing Pinot Noir Berries and the Effects of Two Viticulture Practices Thereon

Creator:: Schmidt, Joseph A.
Abstract:: In recent years, many studies have focused on the molecular and biochemical mechanisms regulating the development of wine grapes. The course of grape berry development is directed by genetic design and is mediated by phytohormones, which regulate grape berry growth and development by orchestrating a complex network of interacting genes,...

Impacts of crop level and vine vigor on vine balance and fruit composition in Oregon Pinot noir

Creator:: Vance, Amanda J.
Abstract:: Vineyard management strategies, including vineyard floor management and crop level management, can be used to influence vine vigor and fruit composition. Two studies were conducted to evaluate the impact of these practices on Pinot Noir in Oregon's Willamette Valley. Managing crop levels is common in cool climate vineyard production though...

Influence of vine vigor and shading in Pinot noir (Vitis vinifera L.) on the concentration and composition of phenolic compounds in grapes and wine

Creator:: Cortell, Jessica M.
Abstract:: In 2003 and 2004 vigor zones were delineated in two commercial vineyard sites based on vine growth variation to assess fruit and wine phenolic chemistry. In 2004, the effects of shading on the accumulation of phenolic compounds were also investigated. Model extractions were done from the shading experiment and the...

Composition of Pinot noir Wines Produced from Different Crop Levels

Creator:: Li, Jingwen
Abstract:: The production of high-quality wine is an important target for wineries worldwide, and low crop level (yield) has been one vineyard management criterion long believed to achieve wine quality. Low yields are most often achieved by removing clusters from the grapevine. Some studies show that cluster thinning can enhance grape...
