Bankers by profession, Jim and Mary are no newcomers to wine. They've owned one of America's oldest wineries, Hermannhof, since 1974. It's located in their home state of Missouri, where Jim was raised in a farming tradition.The wines at Hermannhof are good, but the Missouri climate is not conducive to growing the European varietals that have made France and California famous. This winemaking couple are constructing their dream winery on the Star Lane property. It's dug into the hillside for efficient use of energy and will host some 26,000 square feet of caves for barrel aging.
