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.

What is your favorite undiscovered grape? Trousseau

What was your first experience with an undiscovered grape? Traveling through Italy, we ordered a bottle of Timorasso at a restaurant in Piemonte, and we were blown away by both the richness and delicate balance. We sought bottles out from the producer, now retired, Walter Massa, for the rest of the trip!

What do you love most about the undiscovered grapes? This world of wine is so vast, and there is always something new to discover. And then, these wines we fall in love with slightly change with every vintage, and we get to taste the nuance and hoard our favorites to enjoy with friends.

tablascreek.com

Region: Paso Robles

Owners: The Haas and Perrin families

Winemaker: Neil Collins

About: Tablas Creek Vineyard, in the Paso Robles Adelaida District, is a pioneer of the American Rhone movement and the first Regenerative Organic Certified™ winery in the world.

What is your favorite undiscovered grape? It’s unfair to ask us this! So, let’s go with the two rarest grapes we grow. On the white side Picardan. When we planted our half-acre it increased the world’s footprint by 40%. And on the red side, Vaccarese, where when we bottled it in 2019, we think it was the first 100% Vaccarese from anywhere in the world in 50+ years.

What was your first experience with an undiscovered grape? My first wine tasting memory — the first time I remember tasting a wine and understanding what the adults were talking about — was Gewürztraminer. It really did taste like rose petals, which I thought was so cool.

What do you love most about the undiscovered grapes? They offer an incredible variety of flavors and character, thrive in a variety of climates and soils, and can be remarkably valuable in blends as well as on their own.

Tansy

6450 1st St., Forestville, CA 95436
tansywines.com

Region:  Sonoma

Owners: Kitty Oestlien and Shelley Lindgren

Winemaker: Megan Glaab

About: Kitty Oestlien and Shelley Lindgren founded Tansy Wines in 2020 with friendship and camaraderie at the core, and haven’t looked back. It started with a conversation around a table at Shelley’s A16 restaurant, known for introducing southern Italian wines to diners. They talked about how well these varietals grow in California, and what an incredible adventure it would be to make these wines themselves.

As they started down the path, they also saw an opportunity to create a modern wine brand, one that is owned by women, made by women, and is synonymous with the things they hold near and dear—community, organic, and sustainable farming, and sitting around a table. They’re still building that vision, and thank you for joining them on the journey.

What is your favorite undiscovered grape?

Shelley – Ruche is a small percentage of what is in our Field Blend, but its lavender and floral aromatics are the first notion that there is something wonderful and magical happening, unique to its small production in Italy and even smaller in California.

Kitty – Too hard to choose. We love Fiano.

What was your first experience with an undiscovered grape?

Shelley – Being an Italian-focused sommelier, there is a world of forgotten grapes being rediscovered and enjoyed more than ever before. With such a deep history of viticulture and agriculture, including grapes as a big part of the economy and culture, wine is preserved as a part of the local lifestyle and is important to the heritage and history of Italians. Many of the Italian grapes were planted in the late 1800s in California and are currently having a resurgence.

Kitty – Years ago, I remember that I was dining at A16 and I felt like a Chablis, so Shelley Lindgren recommended a Sicilian Carricante. Wow, DELICIOUS. This changed my perspective on white grape varietals, for the better.

What do you love most about the undiscovered grapes? 

Shelley – Undiscovered grapes tell their story of survival and journey of where they originated and what life was like during their journey, mostly through Europe to the New World.

Kitty – I love how well they pair with the locally farmed fruits, vegetables, and meats that are available in California. Napa and parts of Sonoma have climates that mimic parts of Italy, so the pairings are perfect! I also love the history and origins of these grapes. It’s a great way to learn more about the world!

What is your favorite undiscovered grape? Counoise

What was your first experience with an undiscovered grape? I can still remember the first time I smelled a Gewurztraminer – those hauntingly beautiful aromatics were like nothing I had ever experienced in a wine before – and to this day, the aromatics of this variety remain so special to me.

What do you love most about the undiscovered grapes? I love how they provide distinctive flavors and aromas that expand ones horizons as to what wine can be.

About: Our goal each year is to make the finest wines possible from the best vineyards on the Central Coast of California. We practice post-modern wine-making techniques to bring old world-style wines into the new world. We do work with some the more popular grapes, but even with these we try to bring someting unique to each small lot we make. We also work with some of the more -off-the-beaten-path grape varietals, including Albariño, Picpoul Blanc, Viognier, Grenache Blanc, Roussanne, Marsanne, Tempranillo, Grenache, Mencía, Tannat, Barbera & Sangiovese.

What is your favorite undiscovered grape? Don’t have a particular favorite. I like doing different, interesting and challenging things. I like to bring new experiences to people.

What was your first experience with an undiscovered grape? Can’t remember the first time, but I’ve been tasting European wines for decades now and wines such as Spanish Albariños & Tempranillos, Italian Barolos and Veneto wines, Austrian Grüner Veltliner, French Tannat & Rosés of Grenache have always piqued our interest.

What do you love most about the undiscovered grapes? I love bringing new experience to people who might not have even heard of such varietals.

What is your favorite undiscovered grape? Trousseau

What was your first experience with an undiscovered grape? Jura Trousseau

What do you love most about the undiscovered grapes? That people just taste from a place of pleasure rather than what they THINK the wine should taste like (as is the case with more typical varietals).

Tres Sabores Winery

PO 238, Rutherford CA 94573
www.tressabores.com

Region: Rutherford, Napa Valley

Owner: Julie Johnson

Winemakers: Julie Johnson

About:

Tres Sabores is nestled into the western hills of Rutherford where Julie Johnson and Jon Engelskirger make their home and grow dry-farmed, no till, CCOF and Napa Green certified Old Vine Zinfandel, Cabernet Sauvignon, Petite Sirah, Pomegranates, Meyer Lemons, and Heritage Olives (and raise Golden Retrievers, Sheep, Goats and Guinea Hens, too!). The estate vineyard has a storied history. Originally planted in the 1890’s, then to pears and walnuts during prohibition, then again to grapes in 1972, wine was produced for Frog’s Leap beginning in 1987 and then for Tres Sabores from 1999 through today.

The adventure into truly “uncharted” territory began in 2014 when, almost (not quite, but almost) on a whim, Jon sourced over half of California’s St Laurent production from Dale Ricci’s vineyards in the Carneros and the magic began. Soon, the serendipity factor really kicked in! A chance meeting with Beckham Vineyards owner and ceramic artist, Andrew Beckham, led to the purchase of Novum Amphora to ferment the St Laurent. An auspicious trip to the Sierra Foothills yielded sources of Picpoul Blanc from “Gold Hill” in El Dorado County. Soon, Tres Sabores was making a range of “newly discovered” varietals including a full range of Rhone Whites, Barbera & Tempranillo from El Dorado County, making amphora fermented and aged St Laurent, and a wildly inventive St Laurent blend “Thinking Cap”. Several ‘careful’ trips to the Willamette for more amphora, countless voyages to and from Apple Hill and Placerville later, the Tres Sabores cellar is full of some marvelous wines.

What is your favorite undiscovered grape? Julie: “Picpoul blanc”, for it’s amazing tropical aromatics and rich phenolic personality. Jon: “St Laurent“, because it’s one shiny little dot along the long arc of wine on the planet.

What was your first experience with an undiscovered grape? My husband, Jon, showed up at the winery one September night in 2014 hauling seven tons of St Laurent from the Ricci Vineyard (“Surprise”!!). He unloaded the bins and held a séance to decide what to do with them. (We’ve loved the results over the years and still make what is roughly 10-15% of the St Laurent in California).

What do you love most about the undiscovered grapes? “Undiscovered grapes” are often varieties developed over the centuries by (local) vignerons, cooperatives, monasteries, etc. that for some reason never got a ticket to the ‘big stage’. (To our detriment!) Now, as the best of these cultivars are being rediscovered, planted, and made into wine, we’re reaping the benefits of varietal diversity. These grapes celebrate the heritage of the communities and people who developed them, a broader range of varieties propel vineyards into a place of enhanced sustainability, the spirit of discovering something ‘new’ piques the curiosity and interest of consumers. These are grapes that help to highlight the past by moving everyone into the future.
