I have 40 years of experience, and specialize in the field of viticulture with specific knowledge in the areas of crop loss, vineyard site evaluation and eminent domain. I have published on such topics as yield, compositional and wine tasting differences between thinning levels on cabernet sauvignon, monitoring spread of grape phylloxera by color infrared photography and ground investigation, and crop response of gewurztraminer to cutworm feeding injury by bud position.
