Maynard A. Amerine
(October 30, 1911 - March 11, 1998)

Professor of Enology, Emeritus

American enologist, teacher and writer, was trained as a plant physiologist at UC Berkeley in California before joining the revived Department of Viticulture and Enology at Davis in 1935. There he participated in some of the most important branches of its work, including the assessment of vine varieties for the different regions of california and the re-education of the wine industry to restore and advance the technical knowledge lost during Prohibition. With Albert J. Winkler, Amerine developed the system of classifying wine regions by measuring heat summation. The list of his publications extends to nearly 400 items. In his writings, Amerine has addressed nearly everyone interested in wine: enologists, viticulturists, owners and operators, politicians, connoisseurs, and the public generally. His "Wine: an Introduction for Americans" (1965, with Vernon L. Singleton) is a popular authority; he has also made substantial contributions to the literature of such subjects as wine judging methods, wine and must analysis, color in wines, the ageing of wine, the control of fermentation, and the literature of wine. His combination of practical and theoretical scientific knowledge, connoisseurship, erudition, and prolific output made him, to the American public, the pre-eminent member of that group of UC Davis scientists who renewed research on vines and wines after Repeal of Prohibition. His contribution to the improvement of winemaking standards in California following repeal is of fundamental importance. Maynard Amerine served as chairman of the Department from 1957 until 1962 and retired from the University in 1974. He had remained active as a writer and a recognized general expert on wine, particularly wine in California.
From: Thomas Pinney, Professor of English, Pomona College; author of "A History of Wine in America".


The Maynard A. Amerine Endowed Chair is Dr. Linda F. Bisson, Professor of Enology at UC Davis.

Although retired from the University of California for a dozen years, I still maintain a passion for viticulture and the California wine grape industry. I am able to pursue my interests as a part-time consulting viticulturist working primarily with grape growers.

The prices for wine grapes are at an all time high and this has stimulated a major planting boom in many viticultural areas, notably the Central Coast and the Northern San Joaquin Valley. No longer are the wine grape varieties noted for quality limited to cooler growing areas. There is a strong demand for wine from traditional varieties to be sold at supermarket prices. At the same time the demand for premium quality wine, notably red, has strengthened as well. Thus, it is an exciting time for a viticulturist in adapting to new technology with practices such as canopy management, spacing, supports, rootstock, and clonal selection. All this in a favorable climate of grower-winemaker interactions.

In addition to my activities in viticulture, I devote time to volunteer activities with Suicide Prevention and Davis Lutheran Church, as well as with our children and grandchildren.

Kunkee is Professor Emeritus of Enology from the University of California at Davis, having retired some fifteen years ago. Ralph’s major research and teaching interests have to do with: wine yeast, the malolactic fermentation and the sources and controls of microbiological spoilages of wines. The wine yeast studies involved the characterizations, descriptions and utilities of various yeast strains, now standard winemaking tools—-but at that time, they were just beginning their establishments in the California (hence global) wine industry. The research on malolactic fermentation helped bring understanding to this bacterial activity, and how to control it. These research efforts resulted in the publication of nearly 150 scientific articles and co-author of two enological texts. Several of the research articles, and one of the texts, received prize-winning acclaim.

In addition, he played a helpful role several years ago in the transition of the American taste in wines--and the corresponding change in California wine production--from high alcohol dessert/appetizer wines of the time to the lower alcohol table wines of today, by indoctrinating and urging the use of sterile filtration and sterile bottling as the standard means for wine stabilization. He has visited essentially all of major wine growing regions of the world, and spent twelve-month sabbatical leaves in two of them (Germany and France).

Concerning his teaching, Ralph calculated that he taught over 1000 students in his specialty laboratory course: Microbiology of Winemaking—-and most of those students are now widely distributed throughout the wineries of California and of the rest of the world. Although Ralph has retired, he is still involved in lecture presentations, in consultations and in wine judgings. He is currently instructing in a Distance Learning class, “Introduction to Winemaking,” through UCD Extension, with about 100 students annually.

Ann C. Noble

Professor and Sensory Scientist/Flavor Chemist, Emerita
Retired November 25, 2002
Dr. Noble is busy giving short courses in the US and internationally, participating at national and international meetings in the areas of Wine, Sensory Science or Sensometrics and being a wine judge. She says she is working up the energy to write a book on Wine Sensory evaluation.

She is still involved with the Wine Aroma Wheel , selling tee-shirts and wine aroma wheels www.winearomawheel.com and giving seminars on wine tasting.

Since retirement, she has hiked or backpacked in Australia, California and New Zealand and looks forward to hiking in the mountains and gorge scrambling in summer and cross-country skiing in winter.

I manage to come to the Department and the Wickson Hall office I share with Dr. Kunkee a few times a week and work a little and check my e-mail there. Also, further work is done at the home computer.

In a typical year, I have formally consulted with a few commercial organizations and informally with several more and with students and fellow scientists. Books and papers are reviewed for several organizations. An occasional paper is still presented or published, most recently "Barrels for Wine, Usage and Significance" p. 4-9 in Proc. Symp. Oak from Forest to Glass, 15-16 July 1999, ASEV/ES ST. Louis, MO. This brings lifetime published writings to 214.

Family genealogy, financial news, and family affairs are vigorously pursued. Although not nearly as thoroughly as before retirement, I still try to keep in touch with scientific developments in the fields of phenolic compounds and wine aging.
