[5] Phylloxera would destroy the vineyards just before World War I[5] and Prohibition would postpone any hopes of reopening the winery.

[6] In 1941,[5] 435-acres[5] of Buena Vista land was acquired by United Press news executive Frank Bartholomew at auction.

He replanted some of the original vineyards and in 1943 he bonded the winery and became one of the first entrepreneurs to invest in the California wine industry after Prohibition.

[5] Underwood planted a large vineyard in the Carneros region and built a new modern winery facility.

In 1984 they acquired 1,000 acres, making Buena Vista the largest vineyard estate in the area.

[7] The original hand-dug caves are still on site, and have been re-opened to visitors for tours after a reconstruction effort led by Boisset.

The winery produces 100,000 cases of wine from such grape varieties as cabernet sauvignon, syrah, pinot noir, merlot, sauvignon blanc, zinfandel and chardonnay, as well as a host of wines from unique historical varietals under the "Vinicultural Society" label.

The building, a part of the Buena Vista Winery California Historical Landmark title as #892-1, is a reconstruction of the original villa built by Haraszthy in 1857.
