With all of the mergers and changes of ownership, it's hard to keep track of who owns what winery in California. While it may no longer qualify as "news," 2006 saw a flurry of notable acquisitions of historic estates. Francis Coppola took over Chateau Souverein in Sonoma and renamed it Francis Coppola Family wines. Michael Mondavi purchased Carneros Creek Winery from the Mahoney family. The winery is now the home for I’M, Oberon, and Hangtime wines, while Francis Mahoney retains the Mahoney Vineyards and Fleur de California Brands, which continue to be produced at the winery. And Jess Jackson and family purchased Napa Valley's Freemark Abbey Winery, Sonoma Valley's Arrowood Vineyards & Winery, and Santa Maria's Byron Winery in a bankruptcy sale.
