Don was a serious collector (and consumer) of fine wines for over thirty years. In January of 2003 we brought a small knoll 3.5 miles north of Saint Helena in the heart of the Napa Valley. Included in this two acre parcel was a rocky .75 acre Cabernet vineyard planted in 1996, a very modest vineyard cottage (originally a stone barn built in 1921), a guesthouse and a winery. After an internal remodel of the cottage, many gallons of paint and extensive landscaping, the knoll became our home.
Many years ago we read the book Shibumi, which became one of our favorites: adventure, intrigue, romance, the book has it all. The book introduced us to the concept of Shibumi, a Japanese word describing a physical and emotional state which most nearly translates to “the pursuit of perfection though simplicity” or “Effortless Perfection”. Life on our little knoll in a simple cottage surrounded by vineyards, canopied by majestic oaks and blessed with bucolic 360-degree views, is truly one of perfection through simplicity. Hence when we decided to make wine under our own label, “Shibumi Knoll Vineyards” seemed perfect.
We feel blessed to live in the beautiful Napa Valley and thank you for loving our wines.
It is said by Burgundian vinters that the grape is simply a vehicle that allows the vineyard to express itself. Shibumi Knoll is located in the center of the Napa Valley .3 miles off Highway 29 and a quarter mile from the Napa River. It is on the alluvial fan of Mill Creek and is composed of 80% rock. Thus the wine shows the grace of Napa Valley Cabernet yet has the structure we see in wines from stony hillside vineyards. We harvest the grapes when they are ripe but not overly so. Therefore our Cabernet shows many qualities of a great red Bordeaux. Because of these qualities it is a favorite at The French Laundry.
Our first vintage of Shibumi Cabernet was the 2003. The grapes were processed at Benessere Winery located about a half mile north of Shibumi Knoll. There, while watching the grapes being processed, Don met another vintner, Eugena Keegan, who was bringing in Pinot Noir and Chardonnay grapes from Sonoma County. Eugena asked Don if he’d like to barrel taste her wines. The last wine he tasted, a chardonnay from Buena Tierra Vineyards, he felt was stunning. Eugena was moving to Oregon so he approached the owner of Buena Tierra Vineyards, located on the Russian River in Sonoma county about buying the grapes. The owner explained that because the vines were 35 years old and grape production was down, he was going to replant the 2.4-acre block. Don offered to pay full production price for whatever grapes were harvested, an agreement which has continued for 12 years.
The Shibumi Knoll Buena Tierra Chardonnay has proven to be among the best in the country. The 2005 vintage received a 97 from The Wine Spectator, tied for the highest score given California Chardonnay in the first decade of this century.
This ancient block of vines has produced some incredible Chardonnay vintage after vintage.
In the summer of 2012 Don was walking the Buena Tierra Vineyard with Thomas Brown when Thomas pointed to a small block of Swan clone Pinot Noir and said “I could make some great Pinot Noir from these grapes.” 2012 was our first vintage from this block. Our Pinot Noir is a favorite of many among the wines we produce.
The 2020 Cabernet is a shining example of how delicious, elegant and beautiful our Cabernet can be. The aromas of ripe plum, black cherry and stone fruits entice the nose. The wine is beautifully structured with a soft, velvety feel on the palate. The soft, subtle tannins make it seem that you are drinking a more mature wine. The hint of spice integrated with dark stone fruits segue into a long, lingering and enticing mouthfeel. This vintage is not one to miss, it’s approachable now and destined to be off the charts in years to come

Lastly, the 2020 Cabernet Sauvignon Shibumi Knoll Vineyard is all varietal and spent 22 months in 75% new barrels. It's another beautifully balanced and impeccably made wine from this team that has tons to love, and in this case, it certainly represents a relative value as well. Cassis, darker chocolate, scorched earth, and graphite are just some of its aromatics, and it's concentrated and has full-bodied richness, fine tannins, and the pure, layered, impressive style of the vintage front and center.

100% Chardonnay aged 14 months in 30% new French oak.
Review:
“Stone fruits, buttered citrus, white flowers, and a subtle hint of green almonds all emerge from the 2021 Chardonnay Buena Tierra Vineyard, a medium to full-bodied, ripe, yet elegant Chardonnay. I love its overall balance, and it brings an impressive mix of richness and elegance.”

Shibumi Knoll Chardonnay Corazon del Rio is made from 100% Chardonnay aged 14 months in 20% new French oak.
Review:
“The 2021 Chardonnay Corazon Del Rio Vineyard is another brilliant Chardonnay (these are all made by Thomas Rivers Brown) from the Russian River Valley. Bright citrus, honeyed flowers, and subtle toasty oak notes define the aromatics, and it's medium-bodied, has a fresh, focused mouthfeel, terrific balance, and a great finish. I'd be thrilled with bottles in the cellar.”

Shibumi Knoll Pinot Noir Sonoma Coast is made from 100 percent Pinot Noir, 20 percent in new French Oak.
Review:
“Moving to the reds, the 2021 Pinot Noir Sonoma Coast comes from the Riddle Vineyard in Sonoma and spent 10 months in 20% new French oak. Black raspberries, sappy herbs, spring flowers, and some black tea notes all give way to a medium-bodied, elegant, vibrant Sonoma Pinot Noir with supple, fine-grained tannins and a great finish. It will age, but it's too good to resist today.”

Argot Simpatico Ranch Chardonnay is made from 100 percent Chardonnay.
Powerful aromas of key-lime, white flowers, orange blossoms and a fierce, flinty, sauvage note define a wildly complex nose. Once in the mouth, gracefully pronounced textures coat the palate delivering an exotic interpretation of cool-climate Chardonnay character — lime peel, orange blossom, ginger and clove —lingerings deep into a vibrant finish.
Planted 1978. Shallow volcanic soils on the gently-sloped, south-facing foothills of Bennett Peak on Bennett Valley’s floor. One of California’s coolest Chardonnay vineyards. In the final year of 3-year draught cycle, Simpatico Ranch saw its earliest ever harvest and smallest crop, exposing a reserve of exoticism and minerality previously untapped. A watershed vintage for both the vineyard, and appellation. Night harvested by hand on 9/16, whole-cluster pressed direct to barrel; no settling to ensure maximum lees contact. Barrel fermented on heavy lees. Malolactic fermentation. 16 months in French oak, 50% new. Finished 2 months in steel tank, low Sulphur during barrel elevage.
Review:
The 2021 Chardonnay Simpatico Ranch needs a lot of swirling before it shoots from the glass with notes of lemon tart, orange blossoms, candied ginger, and fresh nectarines with hints of crushed rocks, struck flint, and nutmeg. The medium to full-bodied palate delivers amazing tension, with tight-knit citrus and spice layers and a fantastically well woven satiny texture, finishing long and layered. "We only get about 1.5 tons per acre here," said owner/winemaker Justin Harmon. "This comes from old vines on AXR rootstock."

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.
