When Constellation purchased Ravenswood for $148 million in 2001, the consensus was: “Uh-oh.” No way, we thought, will the giant alcoholic beverage company allow Joel Peterson to make those single-vineyard old vine zinfandels with the same individuality, if at all. These fears proved groundless, as a decade shows. Peterson founded the winery in 1976, and it’s a measure of his dedication — and the slim profits that the winery generated — that he kept his day-job as head of a medical laboratory at Sonoma Valley Hospital until 1992, when the success of the Ravenswood Vintner’s Blend wines enabled him to devote what must be his every waking moment to making wine and running the facility. Under review today are three samples of Peterson’s genuinely old vine products, as in each vineyard — Old Hill Ranch, Barricia, Belloni — contains at least part of the original vines planted more than a century ago. What I like about these zinfandels is that they deliberately eschew the blockbuster qualities of high alcohol, deep extraction and super-ripe fruit; don’t look for anything plummy and jammy in these wines, no cloying boysenberry flavors or alcoholic heat. Peterson’s hallmarks are purity and balance in terms of structure and fruit. He succeeds admirably.
When one steps into Old Hill Ranch, in what is now the Sonoma Valley AVA, there’s a feeling of being on sacred ground. The vineyard was planted around 1880 by William McPherson Hill, who established his farm in 1851. The property passed through his descendents until Otto and Anne Teller acquired it in 1981 and decided not to uproot the historic but abandoned overgrown vines but to restore the vineyard to productivity, working with Joel Peterson, who released Ravenswood’s first Old Hill zinfandel in 1983. The vineyard contains more than 30 varieties of red grapes, the majority zinfandel but also a remarkable array of the well-known and the obscure. It is now farmed by Otto Teller’s stepson, Will Bucklin, who has his own label.

The Ravenswood Old Hill Zinfandel 2011, Sonoma Valley — 75 percent zinfandel, 25 percent mixed black grapes — offers a medium ruby-magenta color and pungent aromas of fresh raspberries and blueberries infused with lavender and graphite, with hints of dried thyme and cedar, all highlighted by some clear wild berry notes. The wine is quite dry but balanced and integrated, its moderately dense but supple tannins and lithe acidity providing support for black and blue fruit flavors inflected by pepper, cloves and a touch of mint. The wine aged 19 months in French oak, 30 percent new barrels, but the influence stays firmly in the background. The finish is clean and well-knit, packed with spice and graphite minerality. 14.9 percent alcohol. Production was 1,200 cases. Drink now through 2018 to ’21. Excellent. About $60.
Barricia looks Italian or Spanish, but it’s a combination of the first names of Barbara Oleson and Patricia Herron, who bought the historic property in 1978. How historic is it? In the 1840s, the land belonged to Sonoma pioneer General Mariano Vallejo, who traded it to his children’s music teacher for piano lessons. Of the 10 acres of zinfandel vines on the estate, six were planted before 1892, the rest in 1995; two acres of petite sirah were planted in 1998. The vineyard now belongs to Mel and Angela Dagovitz.

The Ravenswood Barricia Zinfandel 2011, Sonoma Valley, is a blend of 75 percent zinfandel and 25 percent petite sirah grapes. Fermentation is by indigenous yeasts; the wine aged 19 months in French oak, 40 percent new barrels. The color is intense medium ruby; the wine is bright, clean, fresh and spicy, roiling with notes of macerated raspberries, plums and mulberries wreathed with hints of white pepper, leather and loam. In the mouth, this is, characteristically, muscular and sinewy but light on its feet and enlivened by brisk acidity; still, the tannins build incrementally, chiseled and faceted, along with granitic minerality, leading to a very dry, almost austere finish. 14.8 percent alcohol. Production was 1,250 cases. Try from 2015 through 2020 to ’22. Excellent. About $35.
The property that became Belloni Vineyard was planted around 1900 and acquired by Italian immigrant Ricardo Belloni in 1971. Joel Peterson started making zinfandel from the vineyard after meeting Belloni in 1991. The owner died in 1997, but his widow, his children and grandchildren keep the legacy going. This is a flat, sea-level site in a cool foggy Russian River Valley climate.

The Ravenswood Belloni Vineyard Zinfandel 2011, Russian River Valley, is a blend of 75 percent zinfandel and 25 percent mixed black grapes — Peterson’s magic numbers; the wine is fermented on native yeasts and aged 19 months in French oak, 25 percent new barrels. The color is glowing medium ruby; the vivid bouquet offers spiced and macerated black and red cherries and raspberries with notes of sandalwood and fruitcake, licorice and lavender, staying just on this side of the exotic. As with its sister wine from Barricia, the Belloni ’11 gradually layers its sleek tannins, its granitic core and its seething acidity in seamless balance, while the oak component provides supple framework and foundation. 14.5 percent alcohol. Production was 800 cases. From 2015 through 2019 or ’20. Excellent. About $35.
