The Slate Steep and the Riesling Vine: A Glass at Dr. Konstantin Frank Winery

Driving along the western spine of Keuka Lake, the landscape of the Finger Lakes reveals its prehistoric bones. The hillsides are not merely slopes; they are steep, shale-heavy inclines carved by retreating glaciers ten thousand years ago. In the middle of this dramatic geography sits a modest estate with a profound legacy. Dr. Konstantin Frank Winery isn't just a place to sip a glass of Riesling; it is the site of a radical horticultural defiance that forever changed the American palate.

While the region is now internationally recognized for its world-class cool-climate wines, this wasn't always the case. For centuries, experts insisted that European Vitis vinifera grapes—the Rieslings, Chardonnays, and Pinot Noirs of the world—could never survive the brutal winters of Upstate New York. Today, as you stand on the terrace overlooking the distinct 'Y' shape of Keuka Lake, the thriving rows of old-growth vines tell a different story.

Local Story

The story of this vineyard is inseparable from the man who gave it its name. Dr. Konstantin Frank was a Russian-born viticulturist of German heritage who arrived in New York in the 1950s with a Ph.D. and a controversial theory. He believed that the failure of European grapes in the Finger Lakes wasn't due to the cold, but rather to the rootstock. He argued that if these noble varieties were grafted onto hardy, native American roots, they would not only survive but thrive in the mineral-rich slate soil.

He was dismissed by the academic establishment at the time, but he eventually found a partner in Charles Fournier of Gold Seal Vineyards. In 1962, Frank founded his own winery on a steep, gravelly plot in Hammondsport. He planted the first Riesling, Chardonnay, and Pinot Noir in the Eastern United States. Walking through the '1962 Block' today, you are looking at some of the oldest vinifera vines in North America. These vines have roots that reach deep into the Devonian shale, producing fruit with a complexity that rivals the great estates of the Mosel or Alsace. The air here often carries a crisp, lakeside breeze, a reminder of the lake's 'thermostat' effect that protects these delicate buds from the spring frost.

Experience Guide

Visiting the winery today is an exercise in intentionality. The tasting room, perched high above the water, offers a panoramic view that justifies the trip alone. The experience usually begins with a flight that highlights the estate's versatility—from their sparkling wines produced using the traditional method to their signature dry Rieslings.

When you taste a Dry Riesling here, look for the 'petrichor'—that distinct scent of rain on dry earth—and a bracing acidity that cuts through the fruit. It is a direct reflection of the slate beneath your feet. For those looking for a deeper dive, the 1886 Tasting Room offers a curated experience that pairs limited-production wines with seasonal small bites, often sourced from local Finger Lakes farms. The Zuro app can help you map out a route through the nearby village of Hammondsport to complement your visit with a stop at a local creamery or bakery. Because the winery remains family-owned, now in its fourth generation, there is a palpable sense of stewardship in every glass poured.

The Terroir of Keuka Lake

Keuka Lake is unique among the Finger Lakes for its shape and its depth. The steepness of the hillsides around the lake provides excellent drainage, which is crucial for high-quality viticulture. The shale and slate soils reflect heat back up to the vines during the day and provide the sharp minerality that defines the region’s best white wines. At Dr. Konstantin Frank, the elevation plays a significant role, ensuring the grapes retain the acidity necessary for aging. The winery also produces a notable Rkatsiteli, a Georgian grape variety that honors Dr. Frank's Eastern European roots and serves as a rare find in American tasting rooms.

Beyond the Bottle: Hammondsport and the Lake Shore

A visit to the winery is best paired with an exploration of Hammondsport, a village once voted the 'Coolest Small Town in America.' The town square is a throwback to a slower era, anchored by a park and a handful of independent shops. The Glenn H. Curtiss Museum nearby offers a look into the region's other claim to fame: aviation history. After a morning of tasting, many visitors head to the lakefront at Depot Park to watch the seaplanes take off, a sight that has been common on Keuka Lake for over a century. The combination of deep history, pioneering spirit, and natural beauty makes this corner of the Finger Lakes feel remarkably self-contained.
