Buena Vista in Sonoma is a state historical landmark. It's the first premium winery in California. There had been grapes in the state since the early 1800s, but it was Agoston Haraszthy, the founder of Buena Vista in the mid-1800s, who commercialized and modernized California winemaking.
The winery has gone through numerous owners in the 20th and early 21st centuries and had gotten a little stale.
Jean-Charles Boisset, "the flamboyant Frenchman," purchased the estate less than five years ago and has been quite busy restoring Buena Vista to its past glory -- with some French influence.
At the end of May there was an open house letting folks go through and see what's been done. It's something else!
