There’s a special kind of magic tucked into the foothills outside of Eagle, Idaho, where a small family-owned winery is quietly redefining what Idaho wine can be—effervescent, elegant, and rooted in sustainability. Welcome to 3100 Cellars, Idaho’s first and only dedicated sparkling winery, founded by Hailey and Marshall, a couple whose story is as bright and layered as the wines they craft.
The journey began in Italy. Fresh out of college and unable to land a job during the Great Recession, Hailey volunteered at a small, woman-run sparkling winery in exchange for room and board. “I had a fancy degree in international affairs and religious studies,” she recalls with a laugh, “but once I started making wine, that was it—I was hooked.”
Years later, while working a harvest at Telaya Wine Co. in Idaho, the idea started to bubble up again. Hailey and Marshall took a weekend boating trip in Hell’s Canyon, where she couldn’t stop talking about how no one in Idaho was making sparkling wine. Finally, Marshall said, “Well, do you want to make bubbles?” And that was the beginning.
The name 3100 Cellars isn’t random—it’s a nod to Idaho’s natural wonder. There are over 3,100 whitewater river miles in Idaho, more than any other state, carving its way through Idaho’s wine country and symbolizing the connection between land, water, and craft. For Hailey and Marshall, the river is not just geography—it’s part of the story. Many of their wines are named for iconic river rapids and experiences, adding a sense of place to every bottle.
Even their river-themed business has a deeply personal connection—it’s symbolic of how they met. Hailey was a guest on a trip down the Middle Fork of the Salmon River, and Marshall was her river guide. Their love story started on the water, and that same adventurous, flowing spirit now runs through their wines.
Each wine in our lineup tells a story—one rooted in movement, place, and the untamed beauty of the river. Whitewater, a crisp and vibrant brut-style sparkling Chardonnay, channels the exhilarating rush of river rapids. Pool & Drop, made from Gewürztraminer, captures the rhythm of calm pools and sudden plunges, offering a bright, aromatic profile as dynamic as its namesake. And Pick a Line, a Syrah Rosé, invites you to choose your own path—bold or breezy—just like navigating a tricky stretch of current. Every bottle is an adventure waiting to be poured.
By 2014, they were making their first ton of Chardonnay. Then came the estate vineyard. In 2017, Hailey’s parents—who had been inspired by their daughter’s passion—offered to buy land and plant vines. “They didn’t want to get in the way of our winemaking decisions, but they wanted to support the dream,” Hailey said. The vineyard was planted in the rolling hills just outside of Eagle, and the foundation for 3100 Cellars was laid.
Her parents built a shop and residence on the property, not as a winery at first, but as a getaway and a practical place for family. With time, the team began the process of applying for a conditional use permit to convert the space into a working winery and tasting room.
That process, however, wasn’t without hurdles. “We didn’t realize when we bought the land that it would take a conditional use permit,” Hailey explains. “And we didn’t fully understand what that entailed.” Located in unincorporated Ada County, outside of the city of Eagle, their permit opened the door for public comment—bringing out both supporters and vocal critics.
“There was a lot of concern at first from some neighbors, especially after COVID when tensions were high,” Hailey said. “But since we’ve opened for tastings, we’ve met so many neighbors who love that we’re preserving agriculture out here. They’ve become some of our biggest fans.”
While 3100 Cellars does have the permit to build a full winery building, for now, they’ve held off. “With the restrictions we were given, we weren’t sure it made financial sense to invest millions in a new building,” Hailey said. “So we’ve made the space we have work. It’s not perfect, but it’s home.”
What sets 3100 Cellars apart isn’t just their commitment to bubbly—it’s their dedication to sustainability. Recently, they became Idaho’s first LIVE Certified winery. LIVE stands for Low Input Viticulture and Enology—a certification that promotes environmental stewardship, from native habitat and water conservation in the vineyard, to recycled packaging in the winery.

Running a winery takes a village, and Hailey is quick to praise her team. “I hired a wine club manager last year, and she’s been phenomenal. She handled everything for our recent release brunch,” Hailey said. “I felt like I just showed up and everything was already perfect.”
“We also have a tasting room manager that everyone LOVES when they come to do a tasting at our place. She has made it possible for us to be open consistently Thurs-Sat by appointment and has helped us get through the growing pains of being open for tastings for the first time.”
From a dream sparked in Italy, to a vineyard planted by her parents in Eagle, 3100 Cellars is a true labor of love—and bubbles. With a growing following, sustainable roots, and a deep respect for Idaho agriculture, Hailey and Marshall’s vision is not just thriving—it’s sparkling.
To experience it for yourself, book a tasting, pop a cork, and raise a glass to what’s possible when passion meets perseverance.
