While life among the vines has always held a certain mystique, the idea of owning a vineyard has become more intoxicating in recent years as many estates have experienced acquisitions like Colgin Cellars'. In the last six months alone, another cult cabernet producer, Grace Family Vineyards, sold to a relative newcomer to the industry, Bay Area strategy consultant Kathryn Green; and the high-end Pritchard Hill label, Brand, sold to former Apple executives Jim Bean and Christine O'Sullivan. Yet few winemakers attain a journey like Ann Colgin's, whose progression from wine enthusiast to iconic vintner with vineyards on storied terroirs seems almost mythical.
