absolutioncellars.com

Region: Paso Robles

Owner/ Winemaker: Dirk Neumann

About: We specialize in limited-production, handcrafted, single-vineyard wines from select vineyards all throughout the beautiful Central Coast. With over 20 different varieties and wines made each year, you’ll find something to please every palate. Each wine that we make is the best version of itself – a unique portrait of place and time, an honest expression of where and when the grapes were grown.

What is your favorite undiscovered grape? Cabernet Franc – it’s the parent of Cabernet Sauvignon, Merlot, and Carmenere, yet it is often used almost exclusively as a blending component. I believe it deserves a starring role, which is why I make 100% Cabernet Franc, and a Cab Franc-dominant blend!!

What was your first experience with an undiscovered grape? Trebbiano – like sunshine in a bottle, it’s the perfect wine for all the fresh seafood we have access to right off our docks. While it is virtually unheard of as a domestic grape here in the US, it is the most widely planted white grape in Italy, where it is also used to make balsamic vinegar, and France, where it is known as Ugni Blanc and also used in Cognac and Armagnac production – talk about a versatile grape that makes some of the best things in the world, including of course an amazing white wine!

What do you love most about the undiscovered grapes? I love introducing undiscovered grapes to a new audience that would otherwise have never had the opportunity to try them. There is something so awesome and rewarding when you see someone’s eyes light up at a whole new variety!

ACORN and Ancient Oak

PO Box 20 Fulton, CA 95439
acorn.wine

Region: Russian River Valley

Owner: Melissa Moholt-Siebert

Winemaker: Melissa Moholt-Siebert

About: I am thrilled to have the opportunity to continue the legacy of field-blend wines in the Russian River Valley, started by Bill and Betsy Nachbaur when they founded ACORN about 25 years ago. I bought ACORN from Bill and Betsy and am continuing and extending this vision. In this, I get to work with grapes that are not the “usual” for the Russian River Valley — such as Sangiovese, Gruner Veltiner and Cabernet Franc. I make the ACORN wines using family-farmed, field-blend grapes and native yeast fermentation.

What is your favorite undiscovered grape? Gruner Veltliner. I am excited to explore the textural qualities that can be expressed when grown in the Russian River Valley.

What was your first experience with an undiscovered grape? Drinking Pinot Meunier from the Van der Kamp vineyard was a revelation. Related to Pinot Noir, but a character all its own. So ethereal and enticing.

What do you love most about the undiscovered grapes? Helping to expand knowledge and love of grapes other than the “big 5” of Chardonnay, Cabernet Sauvignon, Merlot, Pinot Noir, and Sauvignon Blanc. There is so much to explore in the world of wine!

What is your favorite undiscovered grape? Picpoul Blanc is probably our favorite grape to work with; always brings a great acidity, green apple character and perfect for California’s climate.

What was your first experience with an undiscovered grape? Bourboulenc! We were the first to plant Bourboulenc in the U.S. and knew it was a blending grape, but was surprised at it’s great acidity, salinity, notes of cantaloupe and kumquat. This grape loves to be paired with fresh sweet corn and is a staff favorite!

What do you love most about the undiscovered grapes? Love the uniqueness of these grapes that you can’t find in the store!

Alamati Wine

90 Easy Street, Buellton CA, 93427
alamatiwine.com

Region: Santa Barbara County

Owners: Cooper Allebrand and Niko Comati

Winemakers: Cooper Allebrand and Niko Comati

About: Alamati is a shared project by two best friends and local Santa Barbara winemakers. Cooper Allebrand and Niko Comati both work as assistant winemakers for prominent wineries in Santa Barbara. We both grew up together in Santa Barbara and started Alamati out of a shared passion for wine, food, and our local community. Santa Barbara County’s uniquely diverse growing regions allow us to work with the grape varieties we love without compromising quality. Lesser-known grapes that began as an experiment for us have become a crucial aspect of our project’s identity. Our goal is to make delicious wines while also working to support and build relationships with local artists, chefs, and musicians. The name Alamati is a blend of our two last names and is a representation of our friendship and 50/50 share of both business and winemaking.

What is your favorite undiscovered grape? We started our project out of love for Nebbiolo. While Nebbiolo is not “undiscovered” by any means worldwide, it is not an easy variety to find in Santa Barbara. Our experience with it has shown that it grows beautifully here. Niko was fortunate to be able to work a harvest in Piemonte and brought back a firsthand knowledge of how classic producers make it. Working with Nebbiolo also led us to add Dolcetto to our collection, which has become one of our favorites as a perfect complement to go along with our Nebbiolo. Dolcetto also probably fits the “undiscovered” label better.

What was your first experience with an undiscovered grape? Dolcetto was the grape we discovered at the start of our project. The grower we work with recommended adding it to our program due to the fact that Nebbiolo needs much more time in barrel for aging. Dolcetto has become our everyday drinker. It needs very little aging time and jumps out of the glass in terms of fruit and energy. It is a fan favorite and something that is very versatile in terms of food pairing as well.

Alamitos Vineyards

23505 Alamitos Rd. San Jose, CA 95120
www.AlamitosVineyards.com

Region: Santa Clara Valley & Santa Cruz Mountains

Owners: Shaun Coleman & Chris Maune

Winemaker: George Troquato

About: Nestled in the historic hills of New Almaden Quicksilver Park, overlooking the shimmering Almaden Reservoir, Alamitos Vineyards is a labor of love born from immigrant roots and pioneering spirit. Our story traces back to the Azores Islands of Portugal, where Shaun Coleman’s grandfather, John Enos Vargas, honed his winemaking craft on the volcanic soils of Faial in the early 1910s. Sailing to California in 1923, he became a cornerstone of Livermore’s wine scene, crafting acclaimed whites—including Sauvignon Blanc for the legendary Old Almaden Winery—just miles from our estate. Today, Shaun, a Silicon Valley entrepreneur and grandson of that trailblazing vintner, partners with fellow innovator Chris Maune to revive this legacy on land once alive with quicksilver miners from Cornwall, Spain, and beyond.

Planted in 2015 with custom UC Davis clones on our five-acre estate, Alamitos honors the past while embracing the undiscovered. We’re passionate about unearthing heritage varietals that thrive in our unique microclimate—warm days cooled by evening reservoir breezes—yielding wines of depth and elegance. At the heart of our lineup is Touriga Nacional, Portugal’s crown jewel and a true underdog in California.

Guided by third-generation winemaker George Troquato’s minimal-intervention philosophy and regenerative farming, every bottle tells a tale of soil, history, and innovation. What makes us a perfect pour for the Festival of Undiscovered Grapes? We’re rekindling Almaden Valley’s vinous heritage—once a viticultural hub—with grapes that whisper forgotten stories, from Azorean voyages to Gold Rush echoes. Join us to taste the thrill of the overlooked: where tech-savvy pioneers meet ancient vines, crafting sips that bridge yesterday’s grit with tomorrow’s grace. Alamitos Vineyards isn’t just wine—it’s a resurrection of the wild, wondrous underdogs shaping California’s soul.

What is your favorite undiscovered grape? Our favorite undiscovered grape to work with at Alamitos Vineyards is Touriga Nacional, our estate-grown Portuguese varietal. This grape is a hidden gem in California, often overshadowed by its role in Port but brimming with untapped potential. We love its small, intense berries that yield concentrated flavors—think vibrant violet, black cherry, and subtle spice—crafted into our standout wines like the “Andorinha” Red, “Laura’s Love” Rosé, and “Umunhum” Port. Its versatility lets our winemaker, George Troquato, play with styles, from bold blends to elegant solo expressions, all shaped by our New Almaden microclimate’s warm days and cool reservoir breezes. Touriga Nacional’s rarity in the region and its ability to tell a story of heritage and innovation make it a perfect fit for the Festival of Undiscovered Grapes, showcasing the bold, overlooked character we’re passionate about bringing to life.

What was your first experience with an undiscovered grape? My first encounter with a lesser-known grape was Touriga Nacional, our estate-grown Portuguese varietal at Alamitos Vineyards. I’d known it as a backbone of Port, celebrated for its rich, fortified depth, but its versatility caught me completely off guard. Years ago, while exploring our New Almaden terroir, we planted Touriga Nacional, intrigued by its potential beyond dessert wines. When we first vinified it, I was stunned by its range—vibrant notes of violet, black cherry, and spice unfolded in ways I hadn’t imagined. It shone as a bold red in our “Andorinha,” a crisp rosé in “Laura’s Love,” and even a nuanced Port in “Umunhum.”

What do you love most about the undiscovered grapes? What I love most is how the unassuming Touriga Nacional, so rare in California, could adapt so brilliantly to our warm days and cool reservoir breezes, revealing a chameleon-like character that bridged heritage and innovation in every glass.

Alta Colina Vineyard & Winery

2825 Adelaida Road Paso Robles, CA 93446
altacolina.com

Region: Paso Robles

Owners: Bob & Maggie Tillman (father/daughter team)

Winemaker: Dallas Parnigoni

About: Tucked high in Paso Robles’ Adelaida District, Alta Colina is a second-generation, organically farmed estate dedicated to distinctive Rhône varietals. We grow wines that reflect our rugged hillside vineyard and share the stories behind grapes that deserve a little more love.

What is your favorite undiscovered grape? Mourvèdre. When Mourvèdre is farmed in the right place, it transcends its reputation as a savory blender and offers incredible complexity.

What was your first experience with an undiscovered grape? Stand alone Mourvèdre was new to us in the 00’s and Paso Robles is an incredible place to farm it. When it’s grown in a place with the right kind of sunshine, it’s always a favorite.

What do you love most about the undiscovered grapes? So often in the US, we’re fed the same 6 or 8 grape varieties. Every wine list and every grocery shelf has so many of the same wines. Part of what we love about wine is the range and diversity of grapes.  Where they can grow, and how they’re expressed through a bottle of wine. Tasting something that tastes nothing like anything I’ve ever tried before is the best and keeps me coming back for more!

What is your favorite undiscovered grape? Counoise

What was your first experience with an undiscovered grape? In 2010, the love affair with single-variety Counoise started with our dry-farmed estate fruit. In earlier years, we blended with Grenache or in our Estate GSM, which we still do and love, but there is something special about a single-variety Counoise.

What do you love most about the undiscovered grapes? The surprise and excitement of a new discovery. Usually, these grapes are made to more authentic expressions, which open a whole new realm of wine and wine drinking.

It’s always a joy to share wines made with lesser-known varietals with our guests and friends, and to widen the consumer’s palate by introducing them to a side of wine where they don’t know what to expect. A wine that initiates a good conversation and brings people together is what excites us the most.
