Vintage Notes

Winter was short and dry, but a cool summer kept the vines from becoming too water stressed. As flavors intensified in the grapes, we picked on September 30th. During eight days of fermentation, with twice-daily pump overs, a rich and intense wine was made. This intensity required more time in barrel for tannins to soften. It shows complex mountain fruit and firm acid. This excellent vintage will be enjoyable over the next fifteen years.


Since the late 1960s, Ridge has made small quantities—ranging from five to seventeen barrels—of wine from this nineteenth-century vineyard. The vines were planted by Alsatian Pierre Klein, a San Francisco restaurateur. While famous for his Bordeaux varietal wines, which won gold medals at the Paris Exposition of 1900, it was his zinfandel plantings that survived Prohibition and the Depression. In 1936, San Francisco’s Schwabacher family purchased Klein’s Mira Valle property, re-naming it “Jimsomare,” for James (father and son), Sophie (wife and mother), and Marie Louise (daughter). In 1966, vineyard manager Elmano Homem pruned the long-neglected vines, and brought the vineyard back to life. Ridge first harvested the zinfandel in 1968. In the 1970s and 80s we shared in replanting the cabernet vineyards, adding some chardonnay acreage as well, and took over the farming of the ranch in 1996 as part of our Monte Bello Estate. We now refer to it by its original owner’s name as the Klein Ranch. (1400’ – 2000’).
