For a time, Zinfandel was thought of as indigenous to the United States. Still, that commonly held belief was proven premature as the connections to Italian Primitivo proved the two nearly an exact genetic match.

Though that association with California has not always been a positive one, Zinfandel has long been an important part of Californian fine wine, and the variety is seeing a resurgence.

Conventional wisdom holds that Zinfandel made its way to California with those seeking their fortunes as part of the Gold Rush in the 1850s. Perhaps the first Zinfandel of note was made by Joseph W. Osborne from a vineyard in Oak Knoll District, now one of the sub-appellations of Napa Valley. The praise his wine garnered resulted in the broad planting of the grape, which grew to the most planted in California in the early 1900s.

America’s great mistake of Prohibition would destroy many, though not all, of these old Zinfandel vineyards and set the grape and American wine back decades. The historical setback would derail the development of California’s fine wine culture.

Many vineyards that remained after Prohibition were located in California’s Central Valley, a region known for quantity production rather than the production of fine wine. Napa Valley, with wines showing promise in the mid-1800s, wouldn’t come to international prominence for more than another 100 years.

As California’s reputation for wine progressed, Zinfandel found itself squeezed out in many places by Cabernet Sauvignon. This trend, coupled with the soaring commercial success of the sickly sweet, blush wine known as ‘White Zin’, has saddled the once noble and benchmark variety in California with a poor reputation.

‘It’s no secret that California Zinfandel has been subject to misunderstanding,’ says Frank Family Vineyards winemaker Todd Graff. ‘In the 20th century, a majority of California Zinfandel planted was either overly jammy and high in alcohol or semi-sweet and pink. There are many of us trying to shift that narrative today.’

Yet it is California’s Zinfandel legacy which may save it and return it to its rightful place atop America’s pantheon of fine wines.

‘Old vineyards produce some of the world’s richest, most characterful and delicious wines’, says Don Hartford, co-owner of Hartford Family Winery. ‘In California, we have 100-year-old Zinfandel vineyards that display intense aromatic, flavour and textural complexities.’

‘California Zinfandel is remarkable for the age of its vineyards, the people who farm them and the vibrancy of the Zinfandel varietal. For these reasons, I think California Zinfandel will be important for years to come,’ Hartford concludes.

Opulence meets restraint in this Mt Brave bottling from the high elevation Mt Veeder AVA in Napa Valley. Aromas of spiced black plums, cinder, smoke and dried floral notes are underpinned by an esoteric mint note. The palate is lush, rich and brooding.

From vines with 100 years of average age, up to 120 in the oldest vines from 60m above the valley floor, comes a mountain Zinfandel grown in cooler climes – savoury with fresh fennel frond, mint and sage with ample blackberry aromas. There is an absolute freshness to this Zinfandel, it eschews stereotypes the grape has become saddled with. Fresh evergreen tips and ripe blackberry fruits meet spiced notes of fig, clove and fresh mint – a deliciously balanced Zinfandel from these masters of Pinot and Chardonnay in Sonoma.

These grapes were picked at 34 brix, and the wine was made in 75% new American oak. The result is ripe and opulent. Made in a digestif style, this sweet late-harvest Zinfandel is rich, ripe and alluring – aromas of rum raisin cake, Christmas spice, evergreen tips and sugar plums. The palate is rich and robust yet shows a real balance. Flavours of ripe damson, candied ginger, chocolate cake and blackberry tart are marked by a sweetened spice and a finish that lingers.

Undeniably drinkable and fresh, the North Coast Zinfandel from Kendall-Jackson may serve as a bellwether of the style of wine the grape can produce with a depth of dark fruits that is lifted by undeniable freshness.
