Upon discovery of the Knights Valley Ranch in 1982, Sir Peter Michael pledged his 100×100 vision for the ranch and winery to remain under family stewardship for 100 years.
Once referred to as Sugar Loaf Ranch spanning just over 600 acres, today the Knights Valley Ranch encompasses nearly 750 acres (304 hectares), inclusive of vineyards on the hillsides of Mount St Helena at elevations reaching 2,000 ft. (609 meters), meandering down through forests to the valley floor where the winery, gardens and olive orchards reside.
Sir Peter and Lady Michael embraced the land as their home away from home, creating a sanctuary for generations to come. Today, their son Paul, and his wife Emily, continue the vision. And with each generation, the commitment and passion deepens.
Peter Michael is an engineer by training, an entrepreneur by daring, and a vintner by adventurous intent. Born in 1938, Peter grew up in Croydon, in South London, not far from Charing Cross. Following meeting Maggie at a ballroom dance class and later marrying, he founded a variety of businesses, ranging from technology to broadcasting, culminating in the establishment of his eponymously named winery in 1987. In 1989, Peter Michael was knighted Sir Peter Michael by Queen Elizabeth II of England.
'Ma Belle-Fille' was named by Sir Peter as a warm tribute to Emily Michael, his "Daughter-in-Law", and mother of the third generation of the family. Planted at the highest elevation on the estate, the marine influence on Ma Belle-Fille vineyard is greater, resulting in cooler daily temperatures in the summer and autumn months. Situated above the summer fog ceiling and exposed to the southeast, the vineyard receives the very first rays of sunshine each morning and remains sunny all day long. This full exposure, combined with cooler temperatures, causes the fruit to mature earlier than the rest of our estate.
Vintage Notes
The combination of a wet winter with significant rains in December through March and cool weather delayed budbreak nearly a month. Flowering and fruit set were also pushed back and the weather during the later flowering was favorable resulting in decent fruit set and slightly above average yields for the Chardonnay vineyards—a marked improvement over the record-low yielding 2022 vintage. The growing season was temperate without major heat spikes allowing the berries to hold onto their acidity which carried through into the wines. Harvest was almost a month later than normal with the last Belle Cote block coming in on November 2nd.

Beautifully perfumed with layers of honeysuckle, jasmine and dried orange peel accented by apricot, vanilla cream and spring flower notes, the 2023 ‘Ma Belle-Fille’ delivers with a rich, creamy entry and generous, structured mid-palate showing great drive and intensity with a long, mouth-watering finish. A truly special wine from an extraordinary vintage.
Review:
So delicious and drinkable from the first whiff to the lingering finish. An uber-chardonnay that packs in all the richness of fruit and smooth spiciness of oak fermentation, with vibrant acidity and a silky texture. Well balanced in a cool, ideal vintage and a great candidate for aging longer term. Drinkable now and best from 2030.

'La Carrière', French for “The Quarry”, reflects the vineyard’s spoon shape and tremendously rocky soils. Situated between 1,200 and 1,700 feet (366 and 518 meters) above sea level on steep mountain slopes exceeding 40 percent in grade, the vineyard has ideal southern and southeastern exposures. The shallow, rocky soils provide excellent drainage with restricted fertility, resulting in lower fruit yields with profound richness and character. ‘La Carrière’ provides a signature complexity and liquid minerality from its mountainous origin.

The name “La Carrière” aptly describes this site’s bowl shape and its tremendously rocky soils. Situated between 1,200 and 1,700 feet above sea level on steep mountain slopes exceeding 40 percent in grade, the vineyard has ideal southern and southeastern exposures. The site’s shallow rocky soils provide excellent drainage, low fertility, and usually the lowest yields on the estate. La Carrière, with its concentrated “liquid minerality,” effectively reflects its mountainous origin.
The 2023 ‘La Carrière’ bursts from the glass with a gorgeous medley of jasmine, white peach blossoms, lemon meringue pie, and white roses with hints of vanilla cream, honey, orange zest, and pastry. A vibrant, juicy entry leads to a well-delineated mid-palate structure and continues into a long, mouth-watering finish. As an expression of the steepest Chardonnay blocks of the Knights Valley ranch, the 2023 ‘La Carrière’ is full of energy with great drive, freshness, and nerve, inviting the consumer to enjoy another glass.
Review:
A driving force of appetizing acidity powers this full-bodied, brilliant, elegant and intricate wine. It offers mineral and citrus flavors in equal measure, starting with a lot of fresh lemon and lime zest aromas, then richer baked apple, lemon blossom and brown butter flavors. Feels so focused, linear and alive. Drink now or
hold. - James Suckling 98 Points
Peter Michael 'L'Esprit des Pavots' Estate Red is made from 59% Cabernet Sauvignon, 22% Merlot, 11% Cabernet Franc, 8% Petit Verdot.
The saturated garnet 2022 ‘L’Esprit des Pavots’ features an intense nose of cassis, black cherry, ripe plum and blackberries with hints of black olive, black tea and baking spices. The soft, supple entry and round generous tannins combine for a plush mouthfeel and elegant finish. This is a fleshy vintage of ‘L’Esprit des Pavots’ which can be approached in its early years but will continue to expand with age.
Review:
“The deep ruby/magenta-colored 2022 Cabernet Sauvignon L’Esprit Des Pavots is a blend of Knights Valley and Oakville… fruity upfront… rich and concentrated… polished tannins and a great finish. A great value in the vintage.”

'Belle Côte', French for “Beautiful Slope”, was named by Sir Peter after the famous ski run in Courchevel, France. The oldest of the four Knights Valley Estate Chardonnay vineyards, ‘Belle Côte’ consistently exemplifies the potential of crafting exceptionally high-quality Chardonnay from our mountain vineyards. Planted at 1,700 to 1,800 feet (518 to 549 meters), Belle Côte has a southeastern exposure and a western border of native trees, which shelter the vines from the hot afternoon sun. These unique attributes create a naturally cool microclimate that provides an extended growing period and slow-ripening fruit, resulting in a later picking schedule that often continues into October (two to three weeks longer than most Chardonnay vineyards in Napa and Sonoma Counties).

As the oldest of the four Peter Michael Winery estate Chardonnay blocks, 'Belle Côte' exemplifies the consistent quality of Chardonnay these mountain vineyards produce. Due to the naturally cool climate of the site’s high elevation, and mitigated exposure to the hot afternoon sun by its southeastern exposure and a stand of trees on its western border, the vines are allowed to slowly ripen. The growing season for Belle Côte typically extends into October, two to three weeks longer than most Chardonnay vineyards in Napa and Sonoma Counties.
With highly expressive aromatics of orange blossom, jasmine, candied orange peel, and rose petal, the 2023 'Belle Côte' showcases its unique terroir and thirty-three-year-old vines with a rich, creamy entry, dense, broad, juicy mid-palate and a lengthy, refined finish. There is a seamless quality to this wine that matches power, gras, and intensity with structure and weightlessness. The 2023 'Belle Côte' can be enjoyed in its youth or after many years of cellaring.
Review:
This extraordinary estate-grown wine from a great vintage is super vibrant, energized and tangy, with vital acidity supporting luscious ripe pear and apple flavors on a silky texture. Can't think of anything it lacks. Seamless, layered, yet structured and fresh, boding well for longer-term aging. It has a melts-in-the-mouth quality and an extra long finish. Drinkable now and best from 2030.

Each year, Sea Smoke's goal for Southing is to create the ideal marriage of complexity and elegance. The ever-changing nose of the Southing exhibits fresh currant, slight strawberry and rose aromas with notes of dried fruit, fennel, clove and nutmeg. The fine tannins and minerality are enhanced by the estate vineyard's characteristic cool climate acidity.
The nose of our the Cabernet Sauvignon shows remarkable purity, opening with juicy fruit-punch and layered notes of blue and red fruit dried with sweet herbs. The palate builds with blackberry pie filling, baker’s chocolate, and freshly ground coffee, underscored by an earthiness of loam and underbrush. Acidity is finely tuned, carrying structure through the middle and sides of the wine. For those who can wait, cellar this bottle for several years. For those who cannot, double decant 4–5 hours before serving and let the wine come fully alive.

Review:
"How do you do Cabernet the Donelan way—and do it in Sonoma? The answer began with archetyping older styles of Cabernet. The vineyard lies near Skipstone, encompassing sites such as T-T Vineyard, Obsidian, and Constant on Diamond Mountain. For Joe Donelan, the goal was to craft a Cabernet reminiscent of what Mondavi was producing in the 1970s and early 1980s—wines defined by freshness, clarity, and balance rather than sheer weight. The result is vivid, bright, and pure-fruited, with an immediate freshness factor. Red berry fruit, cherry, and cassis lead the way, framed by a medium-bodied structure with velvety-textured tannins and a creamy mid-palate that makes the wine deeply engaging and remarkably easy to drink. Sagebrush and black olive notes lend savoury complexity, joined by subtle hints of tobacco, all carrying through to a long, mineral-driven, fruit-focused finish. - Jonathan CRISTALDI"
