Down And Dirty Guide To Napa Valley Zinfandel

We’re talking about Napa Valley Zinfandel. Who’s got the best Zin in the valley? Let’s find out in this down and dirty guide to the best Napa Zinfandel wineries.

While Cabernet Sauvignon reigns supreme in Napa Valley, there’s a grape that deserves more consideration, especially given its longstanding history in the area: Zinfandel.

Primitivo’s cousin, Zinfandel was first planted in California back in the 1830s. DNA testing in the ‘90s revealed Zinfandel is the same as Crljenak Kaštelanski, a Croatian grape. 

Zinfandel once took up the majority of acreage in California until Cabernet Sauvignon overtook it in 1998.

Some protected pockets of Zinfandel still exist in Napa Valley, cultivated and revered by those in the know.

Wait…There’s Zinfandel in Napa Valley? 

Two major events come to the surface in every conversation about American wine history: the devastating effects of phylloxera as well as the long-lasting ramifications of Prohibition.

The pest phylloxera nearly decimated California’s vineyards (not to mention those in Europe) in the 1890s.

Just as winegrowers had pivoted with new, hardier rootstock, Prohibition went into effect at the beginning of 1920. In the thirteen years of the so-called ‘noble experiment’, nearly 700 wineries shuttered in California alone.  

This one-two punch downgraded Zinfandel from being the most widely planted grape in California to playing second fiddle to Cabernet Sauvignon, a grape particularly able to withstand the second coming of phylloxera in the 1980s.

Still, Zinfandel maintains the distinction of being the oldest planted variety in the state.

Old-vine Zinfandel is particularly prized, and as Karen MacNeill points out, while there’s no legal definition, “Many winemakers suggest that a zinfandel vine – like a person – turns the corner, becoming ‘old’ after forty”. 

About Zinfandel in Napa Valley

While Napa Valley is one of the smallest wine-growing regions in the world, its impact on California’s wine identity as well as its popularity with connoisseurs makes it a giant in the industry.

With unmatched microclimate and soil diversity, Napa Valley is uniquely situated to coax excellence from vines planted in one-sixth of the area of famed Bordeaux. 

Not all producers in Napa Valley make their Zinfandel in the same way, yet the appellation’s influence on the grape is apparent.

With very thin skin, Zinfandel grapes can be easily swayed by the terroir of the region. Some Napa producers lean into warm spice and smoke notes brought out by patches of volcanic soil, while others take a Burgundian approach to craft lighter, red-fruited bottlings.

Versatile on the table, Napa Valley Zinfandel can be served with a variety of dishes.

Barbecue, grilled vegetables, roasted lamb, and bold spices are natural pairings. National Zinfandel Day falls on the third Wednesday of November every year.

Though Thanksgiving isn’t for another week, Zinfandel can pair very well with roasted turkey (make room, Beaujolais!).

Best Napa Zinfandel Wineries

The Biale Winery In Napa

Some Napa Valley Zinfandel producers can claim vines older than forty years of age. Robert Biale’s family immigrated from Northern Italy and began growing Zinfandel in Napa in the 1930s.

Perhaps one of the best-known Napa Valley Zinfandels and Biale Winery’s most famous label, Black Chicken, is named for the clandestine way customers would order a jug of Zinfandel from the family in the 1940s. 

The Biale family homestead sold fruits, vegetables, and eggs to the community, receiving daily orders on a party-line phone system.

To keep nosy neighbors in the dark, anyone that wanted an illegal jug of Biale Zinfandel would ask for a ‘black chicken’ in their order. Love it.

The founder of the farm, Aldo, would deliver produce and ‘black chickens’ personally. With the extra boost from this code-name cash, as well as the devotion of Aldo’s descendants, Robert Biale Vineyards now boasts more than 24 unique wines in its portfolio. Some of their vines date back to the 1880s!
