Winemaker Tasting Notes

Aromas of red plum, black cherry, cola, and white peach with earthy undertones. Bold fruit at entry with a medium body. Flavors of lychee, cantaloupe, and baking spices. Full and structured mid-palate tannins that evolve into a long and lingering finish. TG (1/23)

Vintage Notes

This dry growing season began with a chilly winter followed by a warm spring and mild summer. Despite water stress, the conditions led to a typical mid-September harvest. This lower block on Monte Bello with its unique micro-climate, produced an exceptional zinfandel. Barrel-aged for sixteen months, this alluring wine is balanced with bold fruit, rich tannins, and lively acidity. It will develop fully over the next twelve to fifteen years. TG (1/23)


Since the late 1960s, Ridge has made small quantities 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, the Schwabacher family purchased Klein’s Mira Valle property, renaming 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 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.
