Creator:: Watson, Barney, Specht, Anna, and Hellman, Ed
Abstract:: Stuck and slow fermentations are a major concern of winemakers. If the levels of fermentable nitrogen in juice are too low, fermentations will be slower and may stop or 'stick' before all the fermentable sugar is utilized by the yeast. Sluggish and stuck fermentations are also sometimes accompanied by production...

Creator:: Watson, Barney and Price, Steve
Abstract:: Different fermentation practices are generally believed to affect wine composition and wine quality of Pinot noir. Oregon winemakers, for example, commonly attribute differences in color and phenolic extraction to differences in processing. There is, however, little information from replicated trials with controls demonstrating the cause and affect of these perceived...

Creator:: Kennedy, James A., Pastor, Jose Luis, and Watson, Barney
Abstract:: The objectives of this research are to monitor tannin and anthocyanin changes during berry development and over several growing seasons to understand how the vintage effects wine composition. Specifically, the objectives of this research project are : · Determine the effect of berry development on the composition of phenolics (tannins...

Creator:: Sreniawski, Mike and Watson, Barney
Abstract:: Traditionally, winemakers have relied upon 'spontaneous' malolactic fermentation (MLF) from indigenous species which may take weeks or months to go to completion depending upon the wine and the cellar conditions. Control of MLF has increased with the development of pure MLF bacterial starter cultures. Pure cultures started from slants generally...

Creator:: Osborne, James P. and Qian, Michael
Abstract:: Wine aroma is one of the most important aspects of wine quality and yeast contribute a significant amount of the volatile aroma compounds in wine. However, our understanding of the contribution of specific yeast to Pinot noir aroma is still limited. In particular, the contribution of non-Saccharomyces yeast species present...

Creator:: Hjorth, Heather and McDaniel, Mina
Abstract:: The sensory evaluation of the 2000 vintage Pinot noir wines from the Oregon State University viticulture trials at Benton Lane Vineyard was conducted by a panel of 11 semi-trained panelists using a modified version of free-choice profiling. 36 wines were made from 3 replications of the 12 field treatments. For...
