This limited release wine is created from the fusion of two exceptional parcels of 70% Shiraz and 30% Cabernet Sauvignon. This classic blend is matured in the finest oak crafting an intriguing unison that captures the essence of the vineyard and highlights its unique varietal expression.
Vintage Overview
2013 was a very good season with predominantly mild, dry days. Yields were generally low and this did result in some excellent parcels of fruit being harvested. Vine-balance was carefully monitored, resulting in fruit that demonstrates the vibrancy and fruit-derived characters that we strive for in our wines. By all accounts it was a textbook vintage.
Tasting Notes
Deep inky purple in color. Aromas of blackberry, mocha, mint and spices. Lush, ripe palate dominated by black fruits, cherry and chocolate. An expansive palate with black fruits and nicely balanced by oak.
Made with the greatest dedication and care, select parcels were matured in new and seasoned French and American oak for up to 20 months prior to being selected for this blend. Individual barrels from our family estate that best demonstrate the intensity of our fruit, balanced by integrated oak were selected for the final blend, which was then bottled with minimal filtration.
Pairs well with venison, ribeye steak, lamb.
Review:
70% Shiraz and 30% Cabernet Sauvignon. Fruit and oak combine here to produce a powerful, full-bodied red with coffee, toast, blackberry and rick plum flavours pouring through the palate. Tannin taps gently at the brakes: peppercorn and pine notes add lift: creaminess to the texture keeps everything running smoothly. Screwcap. 14.5% alc.

The Grade Cabernet Sauvignon Serpent's Back Napa Valley is made from 100 percent Cabernet Sauvignon.
Review:
The 2019 Cabernet Sauvignon Serpent's Back shows a more aromatic, high-toned side of this site. Bright red/purplish berry fruit, pomegranate, cinnamon and sweet floral accents are all laced together. The Serpent's Back is the most refined of these three Cabernets, but it has plenty of Calistoga punch.

The Grade Napa Cabernet Sauvignon Winfield Vineyard is made from Napa Valley Cabernet Sauvignon.
“2016 produced wines that are very giving, round, coating and streamlined. Year after this year, this bottling aims to highlight the best attributes of the Winfield Vineyard, and also creates a wine that possesses qualities that allow it to age well in the cellar and evolve over many years.
“This wine expresses a focused balancing act of dark, rich black fruit, and a fine tannin structure, illuminated through the core with a laser-like acidity. The wine displays a deep purple-red hue with a cranberry halo. Aromas of cassis, cinnamon, citrus oil, roasted meat, and lilac swell from the glass.
“The palate is marked by a wave of jet-black brambly fruit up front, followed by an exotic spice mid-palate and a long, complex finish that lasts and lasts expressing notes of flowering jasmine, and oolong tea. The silky tannins hold everything together and will certainly allow this wine to evolve in the cellar for at least 7-10 years.” - Thomas River Brown
Review:
Coming from the Winfield Vineyard in Calistoga, the 2016 Cabernet Sauvignon is another brilliant wine from the hands of winemaker Thomas Rivers Brown. This deep purple-colored effort boasts tons of blueberry and jammy blackberry fruits as well a medium to full-bodied, concentrated, yet elegant style on the palate. It has the purity of fruit that’s the hallmark of the vintage, ripe, sweet tannins, and no hard edges, and is already hard to resist.

The 2019 Cabernet Sauvignon Winfield Vineyard is a blend taken from three blocks in the vineyard. A potent, layered Cabernet, the Winfield is super-expressive today. Dark red cherry, licorice, incense and savory herbs all flesh out in a potent, resonant Calistoga Cabernet that hits all the right notes. This is impressive, to say the least.

From the most recognized Napa Valley red blend comes a distinct, new wine. Made in the same iconic style as The Prisoner Red Blend, we proudly introduce The Prisoner Cabernet Sauvignon. Redefining taste once again.
On the nose, blackberry, currant, and plum are layered with dried, crushed herbs and licorice. On the palate, cedar, vanilla, nutmeg, and toasted coconut lead as plum and dried blackberries culminate in a lush, full mouthfeel and a lengthy, balanced finish.
Chef Brett recommends pairing The Prisoner Cabernet with Grilled Ribeye or Aged Gouda Cheese.
It is the purest example of tempranillo grapes from Rioja Alavesa. Coming from a vineyard over a hundred years old with an extremely low production. You can taste a high concentration of ripe fruit, well-bodied, with a final touch of toffee and lime soil plus a perfect acidity which makes this wine fresh and very tempting.
VINEYARD From the Cuba Negra Vineyard in southern Labastida, the El Belisario bottling comes from Tempranillo vines planted in 1910.
ALCOHOL 14.5%
PROCESS Fermented naturally in oak foudre. Malolactic fermentation and aging occur in 100% new French oak barriques over two years.
TASTING Along with its brilliant garnet color, aromas of cherries, dried plums, black pepper, and savory mushroom leap from the glass. The palate is fresh and concentrated with mixed red and black fruit, chocolate, menthol, and coffee. Displays a surprisingly elegant nature. Pair with game, red meat and dark chocolate.
Review:
One of those wines that makes you belief in the special magic of old vines, El Belisario hails from La Greña, parcel planted on limestone rich soils in 1910. Aged in older French barrels, it's a focused, nuanced, wonderfully expressive Tempranillo with raspberry, pomegranate and red cherry fruit, filigree tannins, energetic acidity and sweet, caressing oak spices.

Obsidian Vineyard Syrah is bathed in terroir. The vines experience severe stress, pushing the roots ever deeper through rock in search of water, producing miniature clusters of intense power. Given the wine’s natural propensity for tannin, we take extreme care in the cellar to chisel/whittle its rough edges and leave room for richness to flatter its distinctive scaffold. The mid-palate supports flavors of roasted coffee beans, sarsaparilla, and dark chocolate. The finish marches on long after most wines have tired.
Our estate vineyard — the six-acre Obsidian Vineyard in the Knights Valley AVA — has an incredibly complex soil structure. It takes its name from a layer of volcanic obsidian rock that was discovered when we drilled for water.
Chocolate ganache, black currants, fig, graphite, and an expansive mouthfeel.
Review:
"Joe Donelan believes his Obsidian Vineyard is one of the world’s greatest sites for Syrah. I’ve visited the site twice, and can say candidly it certainly sits among the most striking vineyards I've ever laid eyes on within the U.S. It sits like a rock on a promontory—two switchbacks to reach the top—and the stones under the top soil, quite literally, never stop emerging from the ground. The place has an ancient, almost sacred, temple-like feel. It is consistently swept by afternoon breezes. The vineyard was replanted in 2017 after fires ravaged it. Winemaker David Milner laid out the site at denser spacing than before, at 2,000 vines per acre to keep yields per vine low while still achieving sensible tonnage, averaging around three tonnes per acre. Viognier was planted for co-fermentations, alongside some Cabernet Sauvignon, for a single vineyard bottling of that grape. ‘God put on his viticultural hat when he designed this site,’ says Milner. The vineyard is planted with ENTA 174, 877, and Alban 1 clones, along with Donelan Heritage selections certified virus-free. The wine, the 2023 vintage release (the first from the new vines), was aged for 21 months in 36% new oak and co-fermented with 1.8% Viognier, using 32% whole clusters. And it is positively gorgeous: composed of nine different blocks, each fermented separately, then assembled through sequential blending, with no racking until bottling. From just five-year-old vines, this wine is utterly extraordinary—something oddly achievable from young vines on rare occasion. I tasted this wine from the same bottle over three days. While the high-toned espresso-bean and cedar accents are present at first pull of the cork, they mellow out a day later, and the fruit profile is so vibrant. This is the sign of an excellent wine. I first tasted wines from the Donelan’s Obsidian Vineyard years ago at Tasting Panel Magazine in the late, great Anthony Dias Blue’s office. Cushing Donelan showed the wines, and to this day, I recall the first moment I put my nose into a glass of Obsidian Syrah. In early January of 2026, as I nosed this brand new release of Obsidian Syrah, I was transported straight back to that tasting twelve years ago. What’s remarkable is that the aromatics are unmistakably the same, yet from these new, more densely planted vines, the aromas are more refined—precision-farmed wines from young vines delivering a level of detail and poise that feels beyond their years. So what’s in the glass? Pure red, black, and blue fruit nuances layered with tobacco, white truffle character, violet pastille, and an intoxicating perfume. White pepper notes emerge on the medium- to full-bodied palate, framed by velvety tannins. Iron-like and crushed slate minerality underpins dazzling black cherry and blackberry fruit, brown spices, and blood orange richness. There’s a velvety, iron-fist quality here that exudes polish, complexity, and undeniable quality. You want to drink it now—and you absolutely can—but it will also reward time in the cellar. Either way, you’ll be utterly wowed. And when you realise the price is under £100, the achievement becomes even more staggering. As these vines mature, what will become of them in subsequent vintages? I suspect that as the vines mature, they'll go in and out of phases, but so long as Mother Nature cooperates, I expect this wine to continue to dazzle each vintage. - Jonathan CRISTALDI"

This is the first vintage of the Obsidian Syrah after wildfires torched the vineyard in 2017, leading to significant redevelopment. Throughout all those years, the Donelans have exhibited remarkable patience and a clear sense of purpose. This is their reward: a truly magnificent, towering wine of the highest level.
Knights Valley is one of the most magical grape-growing districts in the United States, but it is not very well known because only a few estate wineries are located there.
The 2023 Syria Obsidian Estate is one of the most profound, moving wines I have tasted in Sonoma County. Blackberry, gravel, incense, chocolate, lavender, and dried herbs race out of the glass. Delicate yet powerful, the 2023 is spectacular. It is also very fairly priced in today’s market.
