A 3 1/2 -mile wildlife corridor protecting access to an ancient spring. A 5-acre pond filled with water captured, treated and stored for reuse. About 1,800 acres of land preserved as open space for elk, wild boars and other wildlife, never to be planted or developed.
Most everywhere you look around Halter Ranch Vineyard in Paso Robles, you find signs indicating the land is as important as the wine. It makes sense when you learn the centuries-old, 2,000-acre ranch is owned by a noted conservationist and philanthropist, Swiss billionaire Hansjörg Wyss.
The wines are far from an afterthought, though. Wyss, who bought the ranch in 2000, has invested heavily in the vineyard, hospitality and winemaking operations.
The vineyard — featuring 281 acres planted with 13 varietals — is governed by a balance of nature and science, with bat and owl boxes, raptor stands and beneficial insect gardens to encourage natural pest control alongside high-tech sensors monitoring transpiration and sap flow that have saved an estimated million gallons of water.
When grapes arrive at the modern, 32,000-square-foot, gravity-flow winery, they are treated as gently as possible. They make their transition to wine without any pumping and wind up in 20,000-square-foot wine caves — the largest in the region — dug 30 to 60 feet underground over six years.
Take one of Halter Ranch’s complimentary daily tours and you’ll emerge from the caves onto the festive patio with plenty of seating, a stone pizza oven and Santa Maria-style barbecue grill. It leads to the winery’s new tasting room, a striking space with sweeping views of the vineyards.
Halter Ranch’s flagship wine — a Bordeaux-style blend named for the property’s 500- to 700-year-old Ancestor Tree, the largest known living coastal live oak in the world — isn’t currently available in the tasting room, but six other releases are sure to please any palate.
A refreshing grenache blanc balances floral and fruity flavors, revealing notes of honey and melon. Strawberry, watermelon and kiwi mingle with a crisp minerality in the dry, Provence-style rosé.
The luscious syrah is layered with dark berries and mocha, while the plush malbec delivers plum on an earthy backdrop. The cabernet sauvignon brings in a bit of malbec and petit verdot to round out the tannins and create a long, rich finish.
Rhone varietals come together in CDP, a fruit-forward blend that balances spice, weight and acidity.
The wines benefit from a blend of art and science. Winemaker Kevin Sass, who came to Halter Ranch from Justin Vineyards and Winery in Paso Robles in 2011, has earned a reputation as a master of the craft. He also employs detailed phenolic, or chemical, analysis in Halter Ranch’s advanced lab, testing for disease, flavor, color and even aging potential.
“We go way beyond Brix,” the sugar-level measurement, Sass said. “We have 50 things we run here.”
One of the best ways to experience Halter Ranch is through the three-hour excursion tour — named best vineyard experience by Sunset magazine’s Travel Awards in 2015. Riding around in a 1984 Land Rover, with scenic stops for wine along the way, you’ll see the sustainable farming practices employed in the Sustainability in Practice (SIP)-certified vineyard.
On the older part of the property, you’ll hear about its history, spanning from its days as a seasonal Native American village to the 1970s, when aviators and celebrities including Ronald Reagan would fly in for barbecues and hunting parties. Also on the property is the historical house built by a hog farmer in 1881 that was used in the 1990 horror movie “Arachnophobia”; the film is shown each year in the barn, which has been converted to event space.
Throughout the new tasting room and winery up the hill, you’ll also experience the luxury of a billionaire-bankrolled expansion, including extensive masonry using stones quarried from the property, pieces from Wyss’ art collection — including a 1960s Alexander Calder sculpture — and an energy-efficient production facility employing natural light and cooling that brings compelling architecture to what’s often a utilitarian space.
To get between the two areas, you cross a picturesque covered bridge built to resemble those in Wyss’ native Bern, Switzerland.
Said Ray King, one of the tour guides, “Hansjörg wanted it to be a bridge from the past to the present.”
