Pedroncelli Winery

1220 Canyon Road Geyserville CA 95441
www.pedroncelli.com

Region: Dry Creek Valley, Sonoma County

Owners: Pedroncelli Family

Winemaker: Montse Reece

About: The Pedroncelli story is the immigrant experience coming to life as the American dream. Founded in 1927 by Giovanni & Julia Pedroncelli, we are a four-generation family winery and grape growers for 98 years.

We have ridden the waves of progress and technology staying true to ourselves and our style. We set our sights on what is important: sharing our wines with generations of wine lovers. We want people to sip and savor the moment whether it is an experience on our estate or at home. Our wines tell the story of longevity, craftmanship and integrity-they tell the story of vintage and vineyard one glass at a time.

What is your favorite undiscovered grape? Sangiovese! The grape itself is famous in Italy but here in California is creates its own delicious and intriguing red wine. I call it California Chianti for short.

What was your first experience with an undiscovered grape? Among the first ‘undiscovered’ grapes I found was a Fiano–so different than the traditional white wines I was familiar with from California. Crisp, deep flavors with a beautiful nose–refreshing and paired well with the seafood dish I was having.

What do you love most about the undiscovered grapes? Undiscovered grapes are the hidden jewels in the wide world of wine. Find one and share it with others who may not know about it. You’ll treasure the moment and be inspired to find more hidden jewels.

Region: Lodi

Owners: Jeff & John Perlegos

Winemaker: Jeff & John Perlegos

About: Growing up in the central valley of California, we’ve inherited a sense of pride from our Greek parents and have continued to farm vineyards and make wine, incorporating the Mediterranean lifestyle and culture into our everyday lives. We don’t make wines that are made to have an instant and powerful impact like tasting room wines; our wines are wines of finesse and elegance, and are made to be enjoyed with friends, family, and food.

What is your favorite undiscovered grape? Assyrtiko – represents our Greek heritage, and makes one of the great wines of the world

What was your first experience with an undiscovered grape? It was Cinsault, and I could smell its wonderful aromas in the restaurant from across the room.

What do you love most about the undiscovered grapes? The mystery of trying something new

Post & Vine Wines

PO Box 5142, Napa CA 94581
postandvine.com

Region: North Coast

Owner: Rebekah Wineburg

Winemaker: Rebekah Wineburg

About: Post & Vine is a North Coast-based winemaking project focused on sustainably-produced wines from historic vineyard sites. Founded by Rebekah Wineburg in 2012, Post & Vine works exclusively with sustainably-farmed old vines and implements a meticulous, low-intervention mentality in the cellar to produce small amounts of artisanal, site-specific wines that deeply reflect the unique places from which they come. All of our wines are produced from hand-harvested fruit, indigenous yeasts, and are bottled unfined and unfiltered. The resulting wines are joyful, honest, and deeply speak to their place of origin.

What is your favorite undiscovered grape? Carignane is my favorite “undiscovered” grape and is the focus of my work at Post & Vine. I have always been captivated by the depth and character that old vines bring to our wines. Old vines possess deep root systems that access nutrients and minerals from far below the surface. They are in perfect balance with their environment, needing few, if any, outside inputs, and this results in grapes with concentrated flavors and a unique expression of terroir. At Post & Vine, we are fortunate to work with Carignane grapes from vineyards that have stood the test of time. Old-vine Carignane exhibits remarkable depth and complexity, offering tasting notes of dark fruits, pepper, licorice, and savory spices. These old vines yield smaller quantities of fruit, but each grape is packed with intensity and character. The resulting wines are a true reflection of their heritage, offering a taste experience that is both rich and memorable.

What was your first experience with an undiscovered grape? I was first introduced to Carignane early in my career while working in the cellar at Rudd Winery in Napa Valley during the 2003 harvest. One day, I noticed a darkly colored variety with large clusters and small berries being brought across the crush pad, destined for a port-style wine for their Edge Hill project. Intrigued by the bright acidity and the unique blend of fruit and spice flavors, I felt compelled to learn more. It turned out that the grapes were from old-vine Carignane grown at the Testa Vineyard in Redwood Valley, Mendocino. I reached out to the Testa (Martinson) family, kept in touch, and when I was ready to start my own brand in 2012, I decided to focus exclusively on old-vine vineyards, producing an Old Vine Field Blend from the Testa Vineyard for Post & Vine Wines.

What do you love most about the undiscovered grapes? I love making wines from these lesser-known varieties. The old vine vineyards that I work with are able to express authentic and honest character and stay true to their origins. The wine represents the past, present, and future all at the same time and I am honored to be a part of their story.

PRIE Winery

15628 N Alpine Rd, Lodi, CA
priewinery.com

Region: Lodi and Red Hills AVAs

Owner: J. Gash

Winemaker: J. Gash

About: Prie is an organic, regenerative vineyard and winery specializing in old world style, low alcohol wines that reflect balanced farming practices and thoughtful winemaking.

What is your favorite undiscovered grape? Prieto Picudo continues to teach me the most about soft approaches to winemaking. Working with this Spanish variety has refined how I think about gentle extraction and letting the grape guide the process rather than imposing too much on it.

What was your first experience with an undiscovered grape? Early on, I explored Vermentino, Nebbiolo, and Mencía. Each one opened my eyes to different possibilities. Those experiences shaped my appreciation for varieties that don’t follow the mainstream playbook and how they can express something unique in our climate.

What do you love most about the undiscovered grapes? The challenge of discovering how to finesse the nuances of the final wine. Vintners and growers are constantly learning, adjusting farming, timing, cellar work, to bring out what makes each grape distinctive. It’s problem-solving that keeps the work interesting.

Rideau Vineyard

1562 Alamo Pintado Rd, Solvang, CA 93463
rideauvineyard.com

Region: Los Olivos District, Santa Ynez Valley, Santa Barbara County

Owner: Martin Gauthier

Winemaker: Adrienne Rule

About: Planted exclusively to Rhône varietals, our vineyard was originally planted to five blocks in 1997 and expanded to a sixth block in 2017. Each clone is planted and farmed in the location and soil that best suits it. Its deep, well-drained soil, combined with the coastal weather influences of the nearby Pacific Ocean, leads to the delicately balanced flavor profile of distinct minerality, baking spices, and earthiness that we covet in our estate wines. With a new vineyard planted in 2023, we have expanded our estate program and added additional varieties.

What is your favorite undiscovered grape? Carignane

What was your first experience with an undiscovered grape? The first time I discovered Viognier, I was unimpressed. But the first time I was able to WORK with Viognier and produce it, I discovered that it was a beautiful, expressive variety that can age for years. After that, I started making it in different styles to explore the possibilities.

What do you love most about the undiscovered grapes? Watching people try them for the first time and realize that there are so many more wine options than they thought.

Ridge Vineyards

17100 Montebello Road, Cupertino, CA 95014
ridgewine.com

Region: Santa Cruz Mountains & Dry Creek Valley

Owners: RIDGE

Winemaker: John Olney, Shauna Rosenblum

About: In 1962, Ridge Vineyards made its first Monte Bello, and two years later, its first Zinfandel. Since that time, Ridge has championed single-vineyard winemaking, searching California for those rare and exceptional vineyards where climate, soil, and variety are ideally matched.

What is your favorite undiscovered grape? Valdigue, also known as Napa Gamay. It’s a fun, lighter style and is a nice complement to our wine program.

What was your first experience with an undiscovered grape? My first experience was tasting our RIDGE Valdiguié from Frediani Vineyard, and it was pretty special. It’s a bit “out of the norm” for RIDGE since we rarely focus on lighter-style reds, and it’s also unique in that it comes from Napa Valley. The wine’s bright, refreshing style is best served slightly chilled and pairs beautifully with a wide range of foods.

What do you love most about the undiscovered grapes? What I love most about these lesser-known varieties is that they often come from historic vineyards and offer a glimpse into how winegrowing was done decades ago. It’s fascinating to taste something that was intentionally planted and popular in the early 1900s; it feels like sipping a piece of history.

San Rucci Winery

6201 Schirra Ct, Suite 7, Bakersfield, CA 93313
sanrucci.com

Region: California’s Central Valley

Owners: The Merz Family

Winemaker: Bill and Tony Merz

About: San Rucci is an urban winery based in California’s Central Valley. The name San Rucci is the combination of our two family names – the San Filippo’s and the Becherucci’s. Because we do not own any vineyards, we can work with grape growers throughout the state to craft a variety of wines, including some Italian varieties that are not often found throughout the New World. Salute!

What is your favorite undiscovered grape? Montepulciano, because it is delicious!

What was your first experience with an undiscovered grape? I was at an industry event. The event had a tasting of wines made from lesser-known grape varieties. The variety that surprised me the most at the time was Graciano. Since then, it has been very fun tasting other lesser-known varieties that are being grown throughout California and the US.

What do you love most about the undiscovered grapes? I think the thing I like the most about the forgotten grapes is the curiosity of what could be. There are so many forgotten grapes that are unique on their own, but then add terroir, and it’s fascinating. There will always be a place for grapes like Cabernet, Zinfandel, and Chardonnay, but there are so many other varieties that make interesting and delicious wines. It is fun to introduce the forgotten varieties to wine drinkers.

St. Amant

1 Winemaster Way, Bldg. I Lodi, CA 95240
stamantwine.com

Region: Lodi

Owner: Barbara Spencer

Winemaker: Stuart Spencer

About: Tim Spencer was a rebel, a troublemaker, an outside-of-the-box thinker. Tim went left when everyone else went right. In the 1970’s, when California was just falling in love with Chardonnay and Cabernet, he planted Touriga Nacional, Tinta Cao, Bastardo and other Portuguese varieties. His Vision was simple: Grow world-class port-styled wines in his Amador County vineyard. The first harvest was sold to an equally passionate winemaker that failed to pay for the grapes. Tim, undeterred, took matters into his own hands, and bootlegged several hundred gallons of freshly fermenting wine. He concluded he was quite capable of going broke himself and didn’t need anyone else’s help. That was 1981, and that wine became his very first vintage port. And St. Amant Winery was born! Over the next two decades, Tim became a leading expert, expanding the St. Amant line-up to include dry table wines, white ports, and tawny ports all from traditional Portuguese varieties. When we moved our winery to Lodi in 1996, our own vineyard was dying of phylloxera, leaving us with no grapes. Tim struck an arrangement with the Lodi Winegrape Commission: if growers brought us two tons of grapes, we’d make the wine and give them 25 cases, keeping the rest. At the time, Lodi had only a handful of wineries, and most of its grapes went to large producers with no interest in showcasing Lodi. We discovered many of the forgotten grapes of early California viticulture. From Barbera to Alicante Bouschet, and 30 years later we continue to produce wines from these Heritage Varieties.

What is your favorite undiscovered grape? When asked about his favorite wine, my father liked to joke that his wines were like children. He always had a favorite, which one just depended on the day. In all seriousness though, I would say Bastardo (Trousseau). Bastardo is an obscure, and aptly named, thin-skinned Portuguese variety with tight clusters, uneven ripening, quick to rot and a real bastard to grow. A variety few farmers would choose to plant, but my dad did, believing his best ports always had a touch of Bastardo. Equally crazy, foolish, or rebellious, after taking over the winemaking in 2006, I doubled down on Bastardo, tripling our planted acres.

What was your first experience with an undiscovered grape? When my father first planted  our vineyard in 1972, he planted 2 acres of an obscure white grape. A grape so obscure that no one had reported planting the variety in Amador County, and it accounted for only 0.7% of the acreage in California. The grape: Sauvignon Blanc.

In the 80’s Sauvignon Blanc plantings soared and my father, always fond of the road less traveled, eventually grafted these vines over to 5 Port varieties which went on to form the backbone of our early work with Iberian varieties.

These early experiences with undiscovered grapes shaped our winemaking philosophy. There is no safety and security when working with the unknown and obscure. No dominant or expected style to ape, and no benchmarks to guide you. Of the 20 or so table wines we produce each year, I think each is remarkably distinct. Our guiding philosophy is not to make wines in a particular style, but to listen to the vineyard, the season and the variety and craft compelling versions of each obscure grape.

What do you love most about the undiscovered grapes? 50 years ago, before today’s bearded beanie-wearing hipster winemakers were even a glimmer in their boomer mom’s eyes, my father chose a different path in California viticulture. His road was not defined by his outfit, or schooling, but by his innate curiosity, entrepreneurial spirit, and love of farming. My dad had a simple vision: To grow world-class port-styled wines in his Amador County vineyard. This was not something he stumbled upon by accident, but an intentional effort of purpose. Some would call him crazy, others foolish, but he rarely cared what other’s thought and instead chose his own path. Today forgotten grapes are at the heart of our winery. We produce wines from obscure Iberian varieties alongside a collection of forgotten Heritage varieties from California’s winemaking past. Some would call us crazy, others foolish, but we have rarely cared what other thought. We have never chased trends or produced wines to please consumers. We produce wines that tell a story.

Starfield Vineyards

2750 Jacquier Road, Placerville, CA 95667
starfieldvineyards.com

Region: El Dorado

Owner: Tom Sinton & Rob Sinton

Winemaker: Rob Sinton

About: Starfield Vineyards is an estate vineyard and winery in El Dorado, halfway between Sacramento and Lake Tahoe — on the Highway 50 corridor near Placerville. Starfield Vineyards is known for its high elevation mountain vineyards in El Dorado and the fresh wines from rare varieties that exhibit the characteristic Sierra Spice from growing grapes in the pine forests of California.

What is your favorite undiscovered grape? Cinsaut is my personal favorite. It was hard to find varietal examples of it before we planted it and it looks almost like a table grape, but it produces a light red wine with vibrant strawberry notes and a hint of leafy-bramble. It’s great straight from the fridge on hot California summer days.

What was your first experience with an undiscovered grape? I always felt like I gravitated toward lesser known grapes so it’s hard to pinpoint the exact moment. I remember going through Cabernet Franc and Assyrtiko phases before I’d ever made it to my Cab Sauv, Pinot, and Chardonnay phase.

What do you love most about the undiscovered grapes? It’s still a rare day when I open a bottle of a variety that isn’t considered an “undiscovered grape”. These varieties offer new drinkers a rare opportunity to discover their own opinions about varieties without the vast input of decades of publications and critics so I think it’s easier to find your own wine-tasting voice when drinking these wines and played an important role in shaping my winemaking (and wine-drinking) preferences.

The Steven Kent Winery

2245 S. Vasco Rd, Ste C, Livermore, CA 94550
stevenkent.com

Region: Livermore Valley

Owner: Steven and Beth Mirassou

Winemaker: Steven, Beth, and Aidan Mirassou

About: The Steven Kent Winery in the Livermore Valley is the preeminent producer of Cab Franc in the US.

What is your favorite undiscovered grape? Cabernet Franc, because it is the most alluring, beguiling, delicious, sexy, food-friendly grape…and it is criminally undiscovered.

What was your first experience with an undiscovered grape? Though I had known of Cab Franc, tasting Loire Valley versions in 2000 opened my eyes to a whole different way of thinking about winemaking and the most important parts of those (and all) wines. Keep the wines as pure as possible and help to shepherd in the most authentic and inherently valuable qualities each grape contains.

What do you love most about the undiscovered grapes? Bottomless allure and complexity, Cab Franc is the sexiest grape alive.
