When you think of world-class wine, your brain probably goes straight to the rolling hills of Tuscany or the foggy valleys of Bordeaux. It definitely doesn't stop in Kewaunee, Wisconsin. But maybe it should. Most people think of Wisconsin and immediately conjure up images of foam cheese hats and bratwurst. Honestly, that's fair. However, Parallel 44 Winery Wisconsin is currently busy proving that the "Frozen Tundra" can actually produce a Petite Pearl that rivals a European red.
It’s all about the latitude.
The winery sits precisely on the 44th parallel north. That’s the same line that runs through Bordeaux, France, and the Piedmont region of Italy. Owners Steve Johnson and Maria Milano didn't just pick a lucky number; they bet their entire legal careers on the idea that this specific slice of Northeast Wisconsin shared a "viticultural soul" with the world's most famous vineyards. In 2005, they planted their first ten acres. People thought they were crazy. Lawyers-turned-winemakers in beer country? It sounded like the setup for a joke. Yet, nearly two decades later, they are the largest producers in the Wisconsin Ledge AVA, an official American Viticultural Area they helped establish.
What Most People Get Wrong About Wisconsin Wine
If you’ve ever had a "Wisconsin wine" that tasted like a fermented juice box, you aren't alone. For a long time, the state's reputation was built on super-sweet fruit wines—think cherry, cranberry, and blackberry. Parallel 44 took a different path. They focus on "cold-hardy" grapes. These aren't your standard Cabernet Sauvignon or Chardonnay vines that would shrivel and die the second a Green Bay winter hits.
Instead, they grow hybrids developed by the University of Minnesota and other cold-climate pioneers. Grapes like Marquette, Frontenac, and La Crescent are the stars here. These vines can survive temperatures as low as -30°F. Basically, they are the survivalists of the plant world.
The result isn't a "fake" version of a French wine. It’s something entirely different. The soil in the Wisconsin Ledge is heavy with limestone, thanks to the Niagara Escarpment. This gives the wine a crisp acidity and a mineral backbone that you just don't find in California. When you sip a glass of Frozen Tundra Red (yes, that's the real name), you're tasting a blend specifically designed to thrive in the Fox Valley's unique "terroir."
The Tasting Experience in Kewaunee
Driving out to Parallel 44 feels like a bit of a trek. It’s about 20 miles east of Green Bay, tucked into a landscape of dairy farms and quiet country roads. Then, you see the Mediterranean-style stucco building. It feels like a glitch in the matrix. One minute you're passing a silo, the next you're looking at a 10-acre vineyard that looks like it was air-lifted out of Italy.
The vibe is surprisingly chill. It isn't pretentious. You won't find wine snobs hovering over your glass telling you they detect notes of "wet pavement" and "pencil shavings."
What to expect when you arrive:
- The Patio: This is the highlight. You can grab a flight and sit outside looking over the vines.
- Wine Flights: Usually around $10 for four generous pours.
- The "Drink Pink": It's a fan favorite. A blend of Frontenac and Foch that’s semi-sweet and way too easy to drink on a Saturday afternoon.
- Cheese Plates: You are in Wisconsin, after all. They pair their wines with local cheeses, which is basically a requirement by law (okay, not really, but it should be).
They also host the Frozen Tundra Wine Fest every February. It’s the largest outdoor winter wine festival in the Midwest. Imagine hundreds of people standing in the snow, wearing parkas, drinking wine. It’s peak Wisconsin.
The Science of the Ledge
Why does this specific spot work? It's the "Ledge." The Wisconsin Ledge AVA is a unique geological feature created by the Niagara Escarpment. This rock formation creates a microclimate. The proximity to Lake Michigan and Green Bay helps moderate the temperatures. It keeps the air just a few degrees warmer in the fall, which gives the grapes a few extra weeks to ripen before the first hard frost.
Without that extra time, the grapes would be too acidic. Steve and Maria were among the first to realize that this "ledge" provided the perfect drainage and sun exposure.
Award-Winning Proof
If you think this is all just marketing fluff, the awards tell a different story. Parallel 44 has racked up hundreds of accolades. We're talking Double Gold medals and "Winery of the Year" titles at international cold-climate competitions. In some blind tastings, their wines have actually scored higher than established labels from California and Italy.
The Petite Pearl is a standout. It’s a newer cold-hardy grape that produces a deeply colored, dry red with soft tannins. It’s probably the closest thing Wisconsin has to a classic cool-climate Pinot Noir or Merlot.
How to Plan Your Visit
The winery has different personalities depending on the season. Summer is for the patio and live music. Fall is for the harvest vibes. Winter is for the "Frozen Tundra" experience.

Actionable Tips for Your Trip
- Download the Wisconsin Wine Wine Trail Map: Parallel 44 is part of a larger network. You can easily hit two or three spots in one afternoon if you pace yourself.
- Try the Bubbler: It’s their sparkling wine. In Wisconsin, we call a water fountain a "bubbler," so the name is a local inside joke. It’s a great palate cleanser.
- Buy a Bottle to Age: While most hybrid wines are meant to be drunk young, some of their reserve reds (like the Marquette Reserve) actually develop nicely over 2-3 years.
- Check the Weather: The patio is the best place to be, but it’s exposed. If the wind is coming off the lake, it can be 10 degrees cooler than it is in Green Bay. Bring a jacket.
Parallel 44 Winery Wisconsin has effectively moved the needle on what people expect from the Midwest. It’s no longer just about survival; it’s about craft. If you find yourself anywhere near the Fox Valley, skip the third brewery of the day and head toward the 44th parallel. You might find that the "Frozen Tundra" tastes a lot better than you imagined.
