Peter is the Executive Director of the Cork Quality Council, a non-profit organization comprised of leading U.S. cork suppliers. The council was formed in 1992 to develop standards for quality assurance practices and to provide an educational resource for natural cork. The CQC has since increased its activities to sponsor research in the wine-cork industry and to manage analytical equipment owned in common by CQC members. Peter currently operates Deerfield Associates, a northern California consulting business involved in wine marketing. Previous positions included president of Windsor Vineyards (California and New York), and president of American Advertising Distributors, a direct mail company based in Mesa, Arizona. Peter joined the Cork Quality Council in 1996 and worked with ETS Laboratories as a co-author on their basic research into the relationship between TCA, corks and wine.
