The Paradigm Winery Estate
Paradigm Winery is located in the Oakville District of Napa Valley just west of Highway 29 and south of the Oakville Grade. The winery is owned and managed by Ren and Marilyn Harris, winegrowers with extraordinarily deep roots in Napa Valley. Marilyn is a third generation grower in Napa Valley and Ren has been farming here since the 1960’s.
They purchased Paradigm in 1976 and began producing wine with the 1991 vintage.
They farm sustainably.
Immediate neighbors of Paradigm Winery are Harlan, Martha’s Vineyard, Dominus, an Opus Vineyard, and a Quintessa Vineyard.
They take 1/3 of their grapes and the rest are sold to Nickel & Nickel, Duckhorn, and Groth.
The annual production is limited to 5,000 cases.
Heidi Peterson Barrett has been making our wine since the first vintage in 1991. Heidi's philosophy in making wines for Paradigm is simple: she feels that she is working with an extraordinary vineyard site that has been farmed impeccably for years. She lets the fruit from this vineyard express its quality and unique terroir with minimal intervention.
The wines are made in a classic style to go with food. The Cabernet Sauvignon barrel aged for 20 months in French oak (only about a third of that is new oak) and for 20 more months in bottle before release. The Merlot ages for 20 months in French Oak (third new) and 14 more months in bottle before release.
Respectable Cab, but lately the Merlot, Zin and Cab Fran have been shining even brighter – they all get the same 20-month French oak treatment; excellent values all around.”

The Paradigm Winery Vineyard
In 1976, it was planted to Chardonnay, Pinot Noir, Chenin Blanc and White Reisling, all commonly grown in Napa Valley. But the Harrises quickly confirmed that the vineyard's soil and microclimate were perfectly tuned for growing the red Bordeaux varietals that inspired their passion for wine. The vineyard is now planted to four blocks of Cabernet Sauvignon totaling 32 acres, three blocks of Merlot totaling 18 acres, 2 acres of Cabernet Franc and one acre of Zinfandel.
This Cabernet Franc is black cherry red in color with aromas of blueberry jam and white pepper spiciness. With wonderful ripeness we were able to make one of our best Cabernet Francs. The wine is very lush across the palate with a silky softness and sweet impression of ripe blueberry fruit. Tannins are very moderate with a nice light texture in the mid palate. This is an easy drinking Cabernet Franc, rich and complete and very enjoyable.
Paradigm Cabernet Franc is made from 85% Cabernet Franc & 15% Cabernet Sauvignon
Paradigm Cabernet Sauvignon is made from 90% Cabernet Sauvignon, 8% Merlot, 1% Petit Verdot, 1% Cabernet Franc
20 months in French oak (only about a third of that is new oak) and for 20 more months in bottle before release
Our winemaking "style" is solely determined by this place or terrior we call "Paradigm." Winemaking is agriculture when you own your vineyards and are able to farm them to promote the very best Earth will give you. All of our selections of wines are made from five varietals on the estate. Every wine is 100% farmed and grown by us.
Complexity in our wines supported by luscious fruit and acidity is our hallmark. Our efforts during harvest and barrel cellaring concentrate on maintaining the freshness from the first day we handpicked each vineyard block. Simple winemaking protocols are employed while crucial “timing” oriented winemaking decisions rule each day.
The 2015 vintage produced delicious concentrated wines in smaller quantity than normal. This black raspberry colored Cabernet has lovely open aromatics of black cherry, berry, and plum layered with a perfect balance of new and used French Oak.

My First comment tasting this wine is "wow!" It's delicious; our flagship wine at Paradigm and it delivers. Dense, deep, ripe aromas of black berry and black cherry-like fruit layered with caramel and toastiness from a nice mix of French Oak barrels. Flavors coat the palate with matching notes in a classic Cabernet Sauvignon presentation. One of our best Cabs to date!
Paradigm Cabernet Sauvignon is made from 96% Cabernet Sauvignon, 3% Merlot , 1% Petit Verdot

Dark Cabernet color with beautiful aromas of black cherry, cassis, plus 5-spice, vanilla. Big, ripe and mouthcoating across the palate. The flavors are similar to the aromas with ripe fruit, berry/cherry pie, moderate tannins, and nice length. This wine shows enough structure to be age-worth, yet soft and balanced enough to enjoy upon release. Flavors linger in this tasty, dense wine. Tastes like Oakville. -Heidi Barrett
Review:
"Pretty cassis and blackberry fruits as well as notes of cedar pencil, spicy oak, and tobacco emerge from the 2016 Cabernet Sauvignon Oakville. Medium-bodied, it has a balanced, elegant texture, moderate tannins, and a good finish. It's a complex, classy wine to enjoy over the coming decade or more. This is a classic, workhorse styled Cabernet from winemaker Heidi Barrett with lots to love. The blend is 87% Cabernet Sauvignon, 7% Merlot, 4% Petit Verdot, and the balance Cabernet Franc, all aged 20 months in French oak."

This wine is deeply pigmented with ruby/garnet color. First sniff is Oakville Cabernet all the way. Nice layers of ripe berry and cherrylike fruit with a matching complement of toasty French Oak from an assortment of Coopers and different barrel ages. Gorgeous across the palate with a silky yet dense mouthcoating impression. Ripeness is key and the result is a wine with perfect balance and flow - just plain delicious. It’s a big, beautiful wine now but has tremendous aging potential. — Heidi Barrett

Deep ruby color with aromas of black cherry and plum, a hint of cedar and soft touch of toasty French oak. Seamless and silky across the palate with a nice mouthcoating texture and nicely balanced acidity for many food pairings. Flavors are similar to the aromas, dark plums and cherries, pomegranate, spice and complimentary sweet vanilla toasty oak. Flavors linger making you want another sip.
The grapes for this wine come from loamy, well-drained soils on our estate vineyard. Dijon and Wente clones are fermented in stainless steel and aged in French oak. This is an elegant chardonnay with a focused mid-palate and the refreshing cool climate acidity characteristic of Sea Smoke Vineyard.
Tasting Notes An elegant Chardonnay with aromas of lemon curd, star fruit, fresh cut peach and wet stone. Complemented by satsuma mandarins and a touch of hazelnut in the focused mid-palate and the refreshing cool climate acidity of our estate vineyard. Winemaking Our estate-grown Chardonnay fruit was picked and hand-sorted in the vineyard before spending the night in our cold room. Chilled grapes were softly pressed and the juice was gently pumped into a stainless steel tank and cold settled. Once the heavy solids were removed, the juice was racked to a stainless steel fermenter, then inoculated for primary fermentation. Following primary fermentation, the wine was racked to barrels, inoculated for malolactic fermentation, then periodically stirred to enhance depth and mouthfeel. The 2023 Sea Smoke Chardonnay was aged for a total of 10 months prior to bottling with no fining and no filtration.
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.
