[1] Charles Bundschu, from Mannheim, Germany, joined the company in 1868, and became part of the family when he married Jacob Gundlach’s daughter Francisca in 1875.

[3] The earthquake destroyed the winery's production facilities, one million gallons of wine, and even Charles Bundschu's home.

Walter, of the fourth generation of Bundschus, planted more grapes after the repeal of Prohibition, but the company did not begin producing wine again until the early 1970s.

Unable to obtain premium prices for Sonoma County grapes at the time despite their high quality (and correspondingly lower yield), he decided that the only way to capitalize on the vineyards' value was to produce his own premium-level wine.

Production was initially 70,000 bottles per year but dropped in the late 1990s, as the company focused on the quality of estate-grown Rhinefarm wines.
