James Osborne, PhD in Food Science, Oregon State University Food Science and Technology, “Managing microbes for prevention of common flaws”. James will address the management of wine microbes, the basic microbiology and how various strategies can affect, control, or result in flaws including recent research that may provide state-of-the-art control techniques.

Dwayne Bershaw, MS in Enology, Southern Oregon Wine Institute, “Managing barrels for prevention of common flaws”. Dwayne will provide instruction on managing barrels and cooperage, the basic issues, and how various strategies can affect, control, or result in flaws.
