There are more than 427,000 acres of grape vines planted in California, covering over 700 miles from Riverside County to Mendocino County. The wine regions in California are divided into four different regions. California would be the fourth largest wine producer on the planet if it were a country.
The 107 American Viticulture Areas include the Sonoma Valley Napa, Rutherford, Russian River Valley, and AVAs. California’s Central Valley is the largest wine region and stretches for more than 300 miles from the northern Sacramento Valley to the southern San Joaquin Valley. Almost 75% of all California wine grapes are produced here including California's bulk, box and jug wine producers like Franzia, Gallo, and the Bronco Wine Company.
California is divided into four regions that include the North Coast, Central Coast, South Coast, and the Central Valley. The North Coast includes Sonoma County, Napa Valley, Mendocino, and Lake County. The Central Coast covers the Santa Clara Valley, San Lucas, Santa Cruz Mountains, Paso Robles, San Lucas, The Santa Ynez Valley, Livermore Valley, and Santa Barbara County. The South Coast includes Temecula Valley, Leona/Antelope Valley, Ramona Valley, and San Pasqual Valley. California’s Central Valley includes the Sierra Foothills and the most notable being Lodi.
Trefethen Family Vineyards Dragon's Tooth Red is made from 49% Malbec 37% Petit Verdot 14% Cabernet Sauvignon.
Our Nana, Catherine Trefethen, was Welsh. Her twin loves of wine and family were the original inspiration for our estate in Napa Valley’s Oak Knoll District. Celebrating our heritage, “Y Ddraig Goch”, the symbol of Wales, adorns this bottle of Dragon’s Tooth, a provocative blend born from the rockiest part of our vineyard.
This wine opens with expressive aromas of cherry and blackberry accented with notes of fig, tobacco leaf, and sarsaparilla. Full-bodied and balanced, the integrated flavors of ripe dark fruit lead to a lush and abundant finish.
Winery Chef Chris Kennedy enjoys Dragon‘s Tooth with earthy and rich cuisine. He suggests pairing it with our Creamy Mushroom Pasta. The complementary flavors, textures, and intensity of both the dish and the wine are stunning.
Review:
“Intrepid aromas of richly peppered blue and black fruit with a sheen of minty refreshment. Structured, polished and densely textured, with indulgent tannins and a penetrating bead of fine acidity. Built for the long haul.”

Winemaking: This wine is a classic Bordeaux blend of 78% Cabernet Sauvignon, 10% Malbec, 8% Merlot, 2% Cabernet Franc, 2% Petit Verdot.
. The 2010 growing season was moderate, thus promoting slow ripening and full flavor development. We hand-harvested and fermented each variety separately, then moved the wines to barrel, where they aged twelve months. Once we determined our blend, we returned the wine to barrel for an additional twelve months, to 'marry' the varietals. We used tight-grained French oak barrels (45% new) from coopers Taransaud, Vicard and Bossuet.
Winemaker Notes:
Complex, rich aromas foretell rich flavors of black currants, allspice and a hint of clove. The wine is full bodied, with velvety texture, smooth tannins and an extensive finish. Beautifully balanced, this Cabernet will age for ten more years.
Alcohol: 14.25 percent by volume
Review:
"Savory, dried red capsicum with cedar, cocoa powder and dried mushrooms on top of black cherries. Juicy and layered with some currants and savory earthy spices on the palate. Not quite deep, but a very elegant and savory expression of cabernet with a very long, subtle finish. A little sweet-sour, but quite refined and approachable, too. Drink now."

Block 21 Cabernet is a single vineyard selection from the Trione Cloverdale Ranch, located on the western flank of the Mayacamas Mountains, in the northern portion of Alexander Valley. The vines, planted in 2001 with Bordeaux clone 337, grow in clay and sandy loam soils underlain with a high percentage of gravel. Cabernet Sauvignon grown in this ideal terroir develops deep, concentrated flavors and fine, smooth tannins.
The Trione Block 21 Cabernet Sauvignon is deep, dark, and foreboding. The wine is rich with black currant and dark chocolate aromas and flavors. Inhale, close your eyes and envision an old saddle, favorite wallet or baseball glove, those rustic leather notes are prominent. The structure is tight but has length and verbosity. This wine is age worthy and will continue to develop for 10 years and beyond. Cheers!
Review:
The winery’s 135-acres of vineyards at Cloverdale Ranch is home to Block 21, sporting some of the warmest temperatures in the area. Aged 24 months in French oak. Broad and sturdy, with backbone and finesse. A gentle giant, its firm, expressive tannins bearing weight on the palate. Dark chocolate, espresso, used saddle leather, and graphite form a consortium of elegance.

River Road Ranch is a 115-acre jewel in the heart of the Russian River Valley AVA. Chardonnay vines thrive in well-drained soils, shrouded with fog cooled nights, ideal growing conditions. The grapes for this wine came from two blocks of twelve and fifteen-year-old vines, planted with clones #4, 95, and 2A-Wente.
Bottled poetry is the description of Trione Chardonnay. Burgundian in style of both nose and palate. Rich and inviting, this wine offers a complex mix of toasty baguette, warm melted brie; silky but with the structure demonstrating the aging potential. The wine is tasting great now but will be awesome for the next 5-7 years.

A tribute to the family patriarch, Henry Trione, this deep red wine is an artful blend of the five classic Bordeaux varieties: 35% Cabernet Sauvignon, 34% Merlot, 13% Petit Verdot, 13% Cabernet Franc and 5% Malbec. Cabernet Sauvignon forms the base structure and Merlot contributes fruit flavors and velvety texture; the Malbec, Cabernet Franc and Petit Verdot add depth, color and spice. We harvested the fully ripe grapes from select blocks on three Trione ranches in Alexander Valley, just ahead of early rains.
Winemaker Notes:
Aromas of black currants, blackberry pie and warm spices are the wine’s first impressions. On the palate Henry’s Blend is soft and supple, a seamless integration of ripe fruit, French oak and fine-grained tannins. Delicious now, the solid structure and abundant fruit suggest this wine will age well for 6–7 years with proper cellaring.
Review:
"This is a rich and flavorful red with aromas of plums, currants, mocha, cloves and burnt sage. Fleshy and textured, with a full body and polished, broad tannins. Lovely creamy texture, with a long and toasty finish. 35% cabernet sauvignon, 34% merlot, 13% petit verdot, 13% cabernet franc and 5% malbec. Drink now or hold."

Chateau de Saint Cosme Gigondas is made from 70% Grenache, 15% Mourvèdre, 14% Syrah, 1% Cinsaut.
The wine shows intense blackberry and fig fruit with licorice, violets, and charcoal on the finish. It is remarkably fresh and finessed given the sun and warmth of the southern Rhône. The unique micro-climate combined with 60-year-old vines and traditional winemaking make Château de Saint Cosme Gigondas the benchmark wine of the appellation.
Grenache is the pale-colored, red-fruited, and potpourri-scented red grape variety of the southern Rhône and can be paired with both rustic and sophisticated dishes. Full-bodied Grenache-based wines are ideal with stews, braises, and grilled meats, while lighter versions can work well with dark fish and tomato-based dishes such as ratatouille.
Review:
This rich and impeccably balanced Gigondas has everything we look for in the wines of this appellation. What a wide spectrum of aromas with everything from raspberry to candied orange, plus a slew of delicate spicy notes and fresh Mediterranean herbs. I love the interplay of richness, fine tannins and lively acidity on the generous, but not expansive palate. Very long, refined finish. From organically grown grapes. Drink or hold.

Signature Cabernet Sauvignon is made from 79% Cabernet Sauvignon and nearly equal portions of Petit Verdot, Malbec, and Merlot.
The Signature Cabernet Sauvignon has been a foundational wine for more than five decades. It is a benchmark for the long-lived hillside wines of the Napa Valley, full of structure and aging potential, yet seductively forward in its concentrated varietal character. The dry, rocky soils of Pritchard Hill produce small, intensely flavorful grapes. Crop thinning allows for full, even ripening and elevates flavor complexity.
Review:
Nine different Cabernet clones joined forces for the 2022 Signature, a wine designated in what the winery offers only in extraordinary vintages. The final blend of 82% Cabernet Sauvignon, includes Petit Verdot, Malbec, and Merlot in small quantities. Luscious, as expected, a bath of puréed black cherries and milk chocolate match with teeth-coating plum skin tannins. Spiced red tea, Italian herbs, and a trace of cinnamon-cedar are left behind on the long, silky finish. - The Tasting Panel, July/August 2025
