National treasures: America's old vines and their dynamic and delicious wines

Humans have a strange predilection for new, young, unblemished things.

In viticulture, economics tends to reward a focus on productivity and efficiency. Visually, this is easy to recognise: uniform rows, immaculate canopies and vines farmed for quick returns.

‘A young vineyard reminds me of an army, where everyone looks the same, trained for a mission,’ says Tegan Passalacqua, director of winemaking at Turley Wine Cellars and the winemaker behind his own label, Sandlands, in California, two brands with an explicit focus on historic vineyards.

In a recent conversation with Passalacqua, he reached for a copy of Scottish-American naturalist and writer John Muir’s My First Summer in the Sierra, where Muir writes about his observations on pines and how, while young trees are ‘very straight and regular in form,’ by 50 to 100 years they ‘begin to acquire individuality, so that no two are alike in their prime or old age.’

Old vines, Passalacqua says, do the same. Each grows to express something different from where it is planted, which, among other reasons, is what makes old vines matter and the very thing modern winegrowing was built to erase.

‘That’s the difference between agriculture and agribusiness,’ he says.

Not just the romance

The case for old vines isn't only about romance. Science is slowly supporting the claim that they can produce higher-quality wines with greater aromatic complexity and phenolic structure.

In the United States, old vines are also a living record of American wine history: the field blends planted by immigrants; the vines that survived phylloxera and Prohibition; the foundational plantings that helped establish whole regions.

Still, there’s no legal definition of ‘old vine’ in the US. The Historic Vineyard Society draws its line at 50 years for currently producing California vineyards, with at least one-third of productive vines traceable to the original planting.

The International Organisation of Vine and Wine defines an old grapevine as at least 35 years old. Either way, there isn't much left – America has only a thin and shrinking stock of truly old vineyards, and almost nothing protecting them beyond the goodwill, stubbornness and love of their growers.

Passalacqua sees old vines as a kind of measuring stick. ‘One of the important factors of old vines is they're very educational,’ he says.

‘There's something the farmers and winemakers can learn from them that you might not learn as easily from young vines.’

He also argues that much of the winemaking that exploded in the 1990s in America was built to meet a specific market demand rather than to explore terroir, and that mindset still lingers in much of the industry.

‘Modern winemakers and modern wine drinkers know what they want it to taste like,’ he says.

‘They're not embracing the character of the site. But with old vines, it's really hard not to.’

Not automatically better, but...

In a different conversation, Shauna Rosenblum, winemaker at Ridge Vineyards' Lytton Springs estate, where vines are over a century old, says old vines have ‘soul.’

It isn't only poetry. If you take Ridge’s old Zinfandel vines, interplanted with Petite Sirah, Carignane, Mataro and other varieties, the wines have a character that comes not from a single grape or uniform ripeness but from the tension of a historic field blend.

Rosenblum also notes the resilience older vines can develop. At Ridge, Rosenblum has watched century-old vines test positive for a disease like red blotch and simply carry on – ripening, producing – while the same virus forces young vines out of the ground.

'When you taste younger vines planted in the '90s next to old vines from 1901, there's more to it,' she says.

The vines that have come through something, in her opinion, are the more interesting ones, like people shaped by hardship and 'in it for the long run.'

Old vines are not automatically better, but time can offer something you can't manufacture: identity. And that happens to be what a lot of younger drinkers now say they want – specificity, unusual grapes, a wine with a story rather than a target flavour.

‘When you first begin your wine journey, do you care that you're drinking old vines?’ asks Rosenblum. ‘Maybe not, but then you taste the difference.’

A growing number of American winemakers are betting their reputations on old vineyards.

Labels like Bedrock, Desire Lines and Sandlands have built devoted followings, producing serious wines from grapes most drinkers couldn't name a decade ago.

They're not only preserving old vines but also perhaps teaching a generation to look beyond famous varieties and taste what old vines offer.
