The winery was born in 2004, when 4 friends, passionate about wine and Argentina, decided to enter the wine world by choosing one of the most elegant and distinguished terroirs for red wine in the province Lujan de Cuyo, best known as the land of Malbec.
Winery Acreage: 48 hectares (119 acres)
OTAVIANO WINERY:
The winery has a very modern design and was built with material from the region. It is surrounded by the vineyards and overlooks the Andes Range.
Traditional and cutting-edge techniques are mixed in our production in order to obtain high quality wines.
The winery has stainless steel fermentation and conservation tanks with temperature control, an underground cellar perfectly conditioned for wine aging in oak barrels and a storage room where bottles finish their maturation process.
LOCATION:
Otaviano Winery and Vineyards is located in the highest part of Alto Agrelo, Luján de Cuyo, 300 meters south of the International Route 7 (Km 8)
The estate has 48 hectares of vineyards with the winery in its centre. The place has an incredible view of the Andes Mountain Range and it is ideal to enjoy our sunsets.
ELABORATION:
Our Wines are designed from the vine. There is a thorough work carried out through the different varietal sectors. The vine load is carefully regulated to obtain the perfect balance of the plant and in so doing, get wines that express the maximum potential of our terroir.
In the winery, the grapes are carefully selected with traditional and cutting-edge techniques. By keeping strict control of all the process variables, we are able to preserve and enhance the quality of our wines. These are characterized for being honest, expressive wines with a perfect balance between the fruit of each variety and the ageing in oak.
Our vineyards are located at 1,050 mts above sea level, at the foot of the Andes, where the thermal amplitude and the perfect sunlight give way to a well balanced and high quality harvest. Different grape varieties are selected from the native land, which has deep ground and sandy characteristics. The crops are carefully handled with accurate viticulture techniques and the environment is well taken care of with low impact agrochemicals. The grapes are harvested in 18 kg cases when the vines express their maximum potential.
MALBEC (24 HECTARES)
This variety from the Southwest of France is the one that has experienced the best adaptation to the Argentinean soil, providing exceptional wines of intense aroma, very concentrated purple color and pleasant taste. Without any doubt Argentina produces the best Malbec specimens in the world. Malbec is made as a light young red wine with fresh fruity aromas or as a wine with good body and storage capacity with highlighted ripe berry aromas. It is grown in every viticulture region in the country and provides the best samples in Mendoza, in the regions of Lujan de Cuyo and Maipú. Because Malbec is an emblematic and standard variety, the wineries in Argentina experience an interesting growth in the international market and it is very well positioned among the best wines in the world.
CABERNET SAUVIGNON (12 HECTARES)
Historically associated with the Grand Bordeaux region, it is the most widely recognized red variety in the world. This is due to the particular adaptation of this vine in different winemaking regions, without losing its essence. It produces a wine rich in tannins and color that blends with other less tannic varieties, such as Merlot or Cabernet Franc. These young wines are rough and hard and this is the reason why they are better aged in oak or in the bottle to tame their consistent structure. They are powerful wines, with pleasant aromas and notes that remind us of berries, green peppers and spices.
SYRAH (6 HECTARES)
Of French origin, it is mainly found in the Rodano Valley and is part of great blends, such as L’Hermitage, Chateauneuf du Pape or Cote Rotie. This grape provides very vigorous, solid wines which are rich in tannins and have long conservation. Aging in wooden casks and bottles suits them really well. These wines have intense aromas which remind us of berries, spices and leather. Just like Malbec, Syrah or Shyraz has adapted quite well to the Argentinean soil, giving excellent varietal and blended wines.
PETIT VERDOT (1.5 HECTARES)
It is a high quality red Wine grape, whose origin is unknown. It was first planted in France, mainly in Bordeaux as a complement to the wines of the region. Its late ripeness did not call the attention of the winemakers at first and was eventually left unnoticed by the middle of the XX century. The name comes from the French and means “small green”, referring to its size and the problem this grape endures when the berries fail to develop properly. Not long ago this grape had a comeback and has become more and more popular, especially in Australia, Chile, Argentina, USA and the original region of Bordeaux. These grapes provide very good color and aromas of berries, spices, chocolate and figs. On the palate, the wine is characterized by strong tannins, good volume and acidity.
CABERNET FRANC (1.5 HECTARES)
Cabernet Franc is a red grape From Bordeaux. Its origin goes back to the XVII century where it was mostly grown for blending with Cabernet Sauvignon and Merlot to obtain wines in the Bordeaux style. Genetically speaking, it is the father of Cabernet Sauvignon and this makes them perfectly compatible in winemaking terms.
Cabernet Franc produces intense red wines with more aromatic, herbaceous and complex notes than Cabernet Sauvignon. On the palate, it is also lighter, softer and less acid.
CHARDONNAY (3 HECTARES)
Chardonnay takes its name from the small French town in the Burgundy area, and is certainly one of the most appreciated varietal wines in the world. It is an easy to grow grape because of its remarkable ability to adapt to different climatic conditions. The grape from cool climates provides predominant fruity notes, such as apple and pineapple whereas the grape from warmer climates in characterized by tropical fruit notes. It takes part in the elaboration of the best sparkling wines in the world. Chardonnay wines take good level of fermentation and aging in oak and therefore provide aromas such as vanilla, butter and honey. Due to the versatility of the grape, it can be found in Argentina in many possible ways, being either fresh and light or very complex.
SAUVIGNON BLANC (3 HECTARES)
It is the main white grape from Burdeaux and the Loira Valley in France and the world. It has adapted very well to different viticulture regions in the world, such as the Northeast of Italy, Chile, Argentina, and the coast valleys of California and Australia. However, it is the Sauvignon Blanc from New Zealand which outstands in the world. It offers herbal and citric aromas, sometimes with smoked or wild notes. In Argentina, this grape has gained an important place among the fine white wines and has a very promising future

Deep red color with violet hues. On the nose, it presents balanced notes of ripe fruit, with spices and herbal aromas that give great complexity. Its aging in oak finishes harmonizing aromatically the wine with notes of vanilla and chocolate. In the mouth, the sweetness of its tannins give a complex and long finish.
Review:
"This has dark, chocolatey character with notes of black fruit, vanilla, pinewood and hazelnuts. Medium-to full-bodied, compact and a little tight with a firm texture and bright acidity. Layered. Needs time to open and soften. Cabernet franc, petit verdot, malbec, cabernet sauvignon and syrah. Drink now."

Review:
Icon is a selection from the winery, that is, of the best barrels of the year, basically with Malbec that occupies 85% of the final blend. The selection is made after a year of aging in barrels. The fruit of this selection is a wine of great depth of flavors, with spicy and herbal touches and with firm, sharp and penetrating tannins. In addition, there are earthy notes that project throughout the palate. An old school wine with an austere structure. One for the Cellar.

"Ripe berry and cassis aromas come with a blast of potent oak, but overall the nose on this Malbec is appealing in a bold manner. Airing is vital to smoothing out the tartaric bite this brings, while flavors of blackberry, dark plum, vanilla and mocha finish long and smoother than the palate. Drink this fully oaked and powerfully built Malbec through 2027. - MICHAEL SCHACHNER"

The Grade Cellar Kingly Project Cabernet Sauvignon is made from Napa Valley Cabernet Sauvignon.
"This is a noble expression of Cabernet Sauvignon" in full regalia, with decadent aromas and a mouthfeel viscous and sleek. "This vintage of the Kingly Project Cabernet Sauvignon enters the scene" -- Thomas Rivers Brown
Review:
The 2018 Cabernet Sauvignon Kingly Vineyard is endowed with tremendous richness and concentration. It emerges from the best spots within Block 5, which is a bit more protected from the elements. The 2018 is a bit closed today, but it has a lot of promise. Time in the glass brings out layers of inky dark fruit and the savory, minerally notes that are such signatures. This potent Calistoga Cabernet needs time to shine, but it is impressive today just the same.

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.
