[email protected]. The Terroir of Pinot Noir Wine in the Willamette Valley, Oregon – A Broad Analysis of Vineyard Soils, Grape Juice and Wine Chemistry by Kathryn Nora Barnard A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Environmental Sciences and Resources: Geology Dissertation Committee: Scott F. Burns, Chair Robert B. Perkins Andrew Fountain Martin LaFrenz Teresa Bulman Portland State University 2016 © 2016 Kathryn Nora Barnard Abstract Terroir is determined by a combination of factors in the vineyard including the grape varietal, geology and soil, soil hydrology, physiography, and climate. Although most studies have examined regional differences in wine flavors and associated provenance of wine based on chemistry, few have examined the chemistry of the soil and the ability to trace that chemistry to grape juice and, finally, to the wine.
