The following article first appeared in Blancpain’s magazine, Lettres du Brassus. Founded in 1735, Blancpain has the distinction of being the oldest Swiss watch house. Its nearly three-hundred-year history has been marked by important milestones in watchmaking: the Fifty Fathoms, the world’s first modern diving watch, selected by the US Navy and navies around the world; the Ladybird, the world’s smallest round mechanical watch; the reintroduction of the moon phase complication credited with starting the revival of mechanical watchmaking in the early 1980s; the world’s most complicated automatic winding wristwatch; and much more. There is a natural affinity between Peter Michael Winery and Blancpain. Both celebrate and honor artisanal handcraft, devotion to quality, and obsessive attention to detail, at the same time supporting important environmental preservation initiatives.

Is this really how a wine tasting is supposed to go? Sir Peter Michael’s son, Paul, had his baptism in the family wine business—now in its fourth decade—from day one, so to speak. Trudging up steep slopes soaring along the flanks of Mount Saint Helena, which dominates the landscape north of California’s famed Napa Valley, Paul worked side by side with the crews on the gritty backbreaking tasks never celebrated in romantic odes to wine but central if one actually wants to produce it: removing stones; clearing trees, stumps and brush; planting vines; and installing irrigation. So it was beyond question that when the first release, a 1987 Chardonnay, left the Peter Michael cellars, a bottle would be expressed to Paul, then enrolled in Switzerland’s prestigious École hôtelière de Lausanne (Lausanne Hotel Management School). How better to celebrate this debut than to organize a tasting with the school’s professor of enology?

What followed was a slashing wound. Far from eager to taste the California wine being offered, the professor’s advice was to steer away, observing: “The important wine you need to know about does not come from California; it comes from France and, of course, a little from Switzerland.” Evidently, news of the Judgment of Paris had escaped his attention. This was, of course, the late Steven Spurrier’s 1976 tasting pitting California wines from Napa against the best that France had to offer: first growth Bordeaux and Grand Cru white Burgundies. Judged by French restaurateurs and sommeliers in a blind tasting (the identities of the wines hidden), a Chardonnay made by Mike Grgich at Chateau Montelena and a Cabernet Sauvignon made by Warren Winiarski at Stag’s Leap sent shock waves around the world with their triumph over their French rivals.

Hobbled by arthritic notions of important wine geography, that Lausanne professor certainly locked himself in a comfort zone of microscopic dimensions. Imagine trying to stretch his imagination to embrace the expanse of what Sir Peter Michael’s winery represents. It is a stitching together of ownership by a British family, vineyards located in California, and inspiration drawn from French Burgundies and Bordeaux. The record of the ensuing decades teaches never to prejudge or to apply blinders. The Peter Michael scorecard: seven wines placed in the Wine Spectator’s list of the top 100 wines of the world, four in the top ten, eleven awarded the rarely given lofty score of 100 points from the Wine Advocate, and numerous others with 99 points. As for the École hôtelière, a dramatic reversal. As its graduates fan out to hospitality businesses around the world, the wine curriculum now fully reflects that globalization. And as the coda to that “tasting that never was” of the 1987 Chardonnay, the school’s tasting room now bears the Peter Michael Winery name.

Yet Sir Peter did not come to California to make wine. He is an engineer by training and was drawn to Silicon Valley in the 1970s to found an electronics company focused on generating special effects for television. The climate and the beauty of the countryside surrounding San Francisco seduced him, planting the notion of owning property somewhere near the Bay Area. That it should be a winery, of all things, grew out of a failed bottle of French wine. Dining in the Fairmont San Francisco’s restaurant, an ordered bottle of French Burgundy disappointed, prompting Sir Peter to ask the sommelier to recommend something local. The sommelier selected a bottle of Chateau Montelena Chardonnay, the winery that upended the French in 1976. It was a revelation. That night Sir Peter vowed that the property he would buy would be a vineyard.

Finding the land was not easy. Sir Peter and his family surveyed some forty different sites in the Napa Valley and its surroundings. Their search eventually brought them to today’s location in Knights Valley, northwest of the heart of Napa Valley. What greeted them on their inspection was a dusty cattle ranch with what could be charitably called a rather neglected Victorian dwelling. But what the family also discovered was a breathtaking pastoral setting, slopes with volcanic soil ideal for growing grapes, and year-round sources of water, with both a creek and small lake. The decision to purchase was made at once. To his European sensibilities, however, what he saw seemed upside down. On the hillsides there were no vineyards: the only plantings were on the valley floor. The hillsides were given over to the cows as pastureland. In France it would, of course, be the opposite with vines on the hills, other agriculture and animals on the flat land. After the purchase, months were devoted to scouring the 800-acre parcel to define the locations of the best soils for vineyards, all of which were found at altitudes above 900 feet, some of which were not only well above that height but also upon rocky slopes with pitches rivaling those of Côte-Rôtie in the northern Rhône region of France. To the locals who followed Napa convention of less labor-intensive valley planting, the Michaels were seen as “mad Englishmen” toiling on the hillsides.

The early ambitions were modest—coyly retiring, in fact. Since these Knights Valley hillsides were not then known for producing world-class wine, the hopes were that a few bottles of claret could be made that would not embarrass the family at dinners with their English friends. Helen Turley was retained as the first wine maker and initial plantings placed upon today’s Les Pavots vineyard. Like all of Peter Michael vineyards, Les Pavots bears a French name—a nod to French traditions—and was conceived to be a Bordeaux blend of Cabernet Sauvignon, Cabernet Franc, Merlot, and Petit Verdot. That decision to feature a Bordeaux blend was bold, as it ran against California convention during the 1980s. At the time, the most prestigious California reds were overwhelmingly Cabernet Sauvignons. Indeed, California labeling laws prohibited selling wines as Cabernets unless the percentage was above 75 percent. This rule placed Bordeaux blends, customarily falling below that limit and that could only be labeled “red wine,” at a disadvantage in the market, since it was Cabernets that consumers had been “trained” to seek out.

Les Pavots in many ways is the symbol of the estate. “Pavots” are poppies, and when the family first saw the land, it was covered with them. Being in California, they were of the golden variety, in contrast with the European species that the Michaels knew best, which are red in color. The logo for all the Peter Michael wines features a red poppy stylized to call to mind as well an English hunting horn.

The first plantings may have been the Bordeaux reds of Les Pavots, but the Chardonnays soon joined. Many in the wine world have had doubts about the wisdom of trying to produce Bordeaux-type wines and Burgundy wines, such as Chardonnay, at the same time. This was the view offered by Jean-Guillaume Prats, the CEO of the renowned Domaines Baron de Rothschild (Lafite) and the former CEO of Château Cos d’Estournel in Bordeaux. During a lunch with the family, he counseled that, “The thing is either you are Bordeaux or Burgundy, but you can’t be both.” Sidelight: that advice may have reflected beliefs at the time, but today several owners straddle the two regions. The Chardonnay vineyards lie above Les Pavots, extending up to an elevation of 2,000 feet. The higher elevation exposes them to cooling sea breezes, essential to achieving elegance and balance in the otherwise warm climate of California.

The soils on the upper slopes also offer more compressed volcanic ash, ideal for Chardonnay, giving the wines a natural acidity for freshness. Currently there are four distinct vineyards planted in Chardonnay: La Carrière (the quarry), which is the steepest with a 46-degree slope on one of its parcels; Belle Côte (the beautiful slope); Mon Plaisir (my pleasure); and Ma Belle-Fille (my daughter-in-law, named after Paul’s wife, Emily, Sir Peter quipping that many brownie points were earned by appending that name). As the name suggests, La Carrière boasts the rockiest soil, lending its bottlings the most pronounced mineral notes. Belle Côte has a deeper soil, giving it added richness and exoticism. Mon Plaisir is planted with a classic California Chardonnay clone known as Old Wente; the other vineyards are planted with a mix of historic California clones and the French Dijon clone. The largest and the highest in elevation of the four is Ma Belle-Fille. Its elevation gives it an extra dimension of complexity. For the future, a new parcel has been cleared on the upper slopes. Both its wines and name are waiting in the wings, as for the moment it is simply called “Vineyard Nine.”

With this diversity of elevations and undulating exposures, Peter Michael adheres to the French practice of harvesting by block. Each of these vineyards is subdivided into blocks that take into account the different degrees of ripeness of the fruit during the harvest period.

The family’s affinity for Burgundy is expressed further in its Seaview plantings. Seaview is found in the hills bordering on the Pacific, a ninety-minute drive to the west in the Fort Ross-Seaview AVA. This is Peter Michael Winery’s site for Pinot Noir. Although the parcel comprises some 400 acres, plantings are confined to a mere 29 acres. As with the Knights Valley vineyards, Seaview’s are found high up east-facing slopes, thus limiting the effects of ocean winds, providing a degree of shelter from winter storms, and, vitally important, placing the vines above the fog line. In many ways the microclimate is that of the Gualala River, which lies at the base of the hills. As with the Chardonnays, there are distinct cuvées: ‘Ma Danseuse’ (my dancer, as Sir Peter met his wife in dancing school); ‘Le Caprice’ (named after the capricious nature of Pinot Noir); and ‘Clos du Ciel’ (the sky). ‘Ma Danseuse’ is the most elegant of the three; ‘Le Caprice’ offers riper fruit and denser texture; ‘Clos du Ciel,’ found in the warmest section of the estate, is the most complex and age-worthy.

There are several other noteworthy bottlings. From Knights Valley, ‘L’Après-Midi’ (afternoon). This is found on a parcel just below Le Pavots and is a classic white Bordeaux blend of Sauvignon Blanc and Sémillon. ‘Point Rouge’ (red dot) represents the rarest of the Chardonnay offerings. It is a blend of the finest barrels from Knights Valley. Its name refers to red dots that are placed upon the barrels that are judged to be the best. Another small-blend Chardonnay, ‘Cuvée Indigène’ (indigenous cuvée), is a blend of Old Wente clones from select estate vineyards. There is one offering that originates in the heart of the Napa Valley from Peter Michael’s vineyard on the eastern hills above the famed Oakville bench. Bearing the Au Paradis (in paradise) name, this is a small-production Cabernet Sauvignon.

Taken together, the Peter Michael estates comprise over 1,100 acres. Yet only 200 acres have been planted. The remaining acreage has been left as wildlife corridors. As a testament to the family’s commitment to be worthy stewards of the land, all the estates have been officially certified “Fish Friendly Farming” and “California Sustainable.”

Managing vineyards this dispersed is an enormous undertaking. For more than three decades Sir Peter has entrusted the care of his vines to Javier Aviña. He has been called upon to do more than the traditional planting, plowing, pruning, irrigating, and other core tasks of vineyard care. Aviña keenly observed the dangers of wildfires that have in years past ravaged sections of the hills bordering the Napa Valley. Prescient, he convinced the family that it must invest in aggressive removal of dead trees, overgrown dry brush, and other wildfire fuels that surrounded the Knights Valley property. His foresight proved its merits in 2020 when a virulent wildfire propelled by fierce winds broke out in the region. Areas not as wisely cleared were destroyed; all the vineyards and buildings on the estate escaped unharmed. His current challenge: rationing irrigation water from reservoirs on the slopes badly depleted by two years of drought.

Equally vital has been the engagement of the estate’s winemakers. The succession represents a who’s who of California winemaking stars. Working with their first winemaker, Helen Turley, the family established the style that has been carried forward for nearly four decades. There has been a tendency in some quarters in Napa to emphasize blockbuster power over refinement and complexity. The family inclined away from the punch-in-the-nose school of superman wines, insisting on a Burgundian approach favoring complexity, nuance, and a clear expression of the particularities of the vineyard, a property that the French call “terroir”. She was followed by Mark Aubert, who after several years went on to found his own, now acclaimed, winery in Napa. Two French winemakers followed Aubert’s departure, Luc and Nicolas Morlet, who remain close to Peter Michael as consultants. The current winemaker is Robert Fiore. A good part of his educational background points away from winemaking, as his degrees were in geology and geophysics. Those degrees were followed by the pivot toward wine with studies of viticulture and enology at UC Davis and most importantly, a long sojourn in Burgundy working at Domaine Michel Lafarge in Volnay. That combination has given Fiore a perfect platform for his winemaking. UC Davis enjoys worldwide renown for its advances in all the scientific and technical aspects of winemaking. Burgundy is where the emotion, soul, and artistry of winemaking find their finest expression. Fiore is proud to have a foot in each camp.

“Working with their first winemaker, the family established the style that has been carried forward for nearly four decades.”

Sir Peter is modest about the toil and mammoth investments over four decades that have placed the family’s offerings at the very pinnacle of California winemaking, preferring to talk instead about the role of luck at critical times. He recounts finding legendary critic Robert Parker at an adjacent table in a Calistoga restaurant. Parker and his wine ratings then ruled the world’s wine markets, anointing winners and shattering reputations. As Sir Peter describes it, he saw both the opportunity of a lifetime and peril as he approached Parker’s table to introduce himself, relieved to find one of the family’s wines already there. After that first meeting Parker included Peter Michael wines in tastings conducted in France, with the bottles winning top notes. Another stroke of good fortune was having the wines selected for inclusion at state dinners at the White House.

An anonymous wag once observed that after fifty years of work, he became an overnight success. In the case of Peter Michael wines, it has likewise spanned decades. One thing has become clear
over this time span: the family’s dedication to their “100 × 100” credo, a 100 percent commitment to the land for 100 years.
