Lower Lake, Calif. -- Lake County continues to be the North Coast wine region’s Cinderella -- before the fairy godmother appeared. But a large new vineyard development there could wave the magic wand and attract more visitors to the geographically attractive county north of Napa. Clay Shannon, a local grower and vineyard manager who started making wine a few years ago, is developing a 240-acre plot on rolling hills overlooking giant Clear Lake into five separate wineries plus amenities prohibited in Napa like inns, a deli and event facilities -- as well as a farmers market selling produce from his and others’ farms and multiple tasting rooms. In the works for more than two years, Shannon is already hosting weddings, barbecues and other functions at the vineyard. Its first tasting room opens at the end of July.
