WINEMA k ING turable Brett population, thus treating the symptom rather than the cause. Oops. NES is not only more accurate and sensitive, to reach its threshold of detectability quantifies the size of the original popula- tion. Through a photoactive method that counts only viable cells, Mills showed evi- dence that SO2 increases the viable uncul- it also can be done in 90 minutes as opposed to the two- to 10-day wait time normally as- sociated with plating. As DNA probe tech- nology becomes refined in the coming years, a brave new microbial world, which was there all along, awaits our comprehension. Also of interest Even though not directly related to PMW, I can't omit mention of some other highlights: • A fascinating CAT scan talk by Andrew McElrone about drought tolerance and PD resistance, including a sobering assessment of water politics in California. • An update on GC MS/MS and HS-SPME for more precise detection of haloanisoles (e.g. cork taint) as well as key volatiles such as terpenes and norisoprenoids by Sue Ebeler, who also contributed substan- tially to several other presentations. Dr. Ebeler also presented Dynamic Changes in Volatiles in Cab Sauv with and without References 1. r. Gawel, a. Oberholster, and I.l. francis.

Rodgers of Cypress Semiconductor for his generosity in setting the new Da- vis winery up with 152 of the world's most high tech experimental fer- menters, but Roger Boulton certainly tried. The new fa- cility certainly de- serves a visit. • David Block was equally effusive about the Davis campus's first LEED-certified building, the Jess S. Jackson Sustain- able Winery Building, conceived by Dr. Boulton's outrageous vision and funded by the Jackson family prior to Jess' un- timely death. • Lest it escape attention, one of the most medically significant presentations was that of Dr. Waterhouse's research assistant Ying Yng Choy, who showed that grapeseed pro- cyanidins persist into the colon and can ex- ert local biological action resulting in a pro- tective effect against colon cancer. Roger Boulton Clark Smith is winemaker for WineSmith and founder of the wine technology firm Vinovation. He lectures widely on an ancient yet innovative view of American winemaking. SUPPORT RESEARCH & WINE INDUSTRY NEEDS THROUGH THE AMERICAN VINEYARD FOUNDATION Finding Solutions Through Research tolerance to abiotic stressors like drought and salts, with new selections from the Walker program now available to growers. Drs. Walker and Cousins continue to develop rootstocks resistant to phylloxera and nematodes while displaying Dr. Qian and others are studying the impact of closures with different oxygen transmission rates on aroma development with a focus on volatile sulfur compounds during post bottling aging. This work should help the industry make informed closure selections.
