Behind The Wine: RAEN
Few families have shaped American winemaking as profoundly as the Mondavis. Yet on the windswept hillsides of the Sonoma Coast, brothers Carlo and Dante Mondavi have forged an identity beyond their family's Napa Valley roots. Founded in 2013, RAEN reflects the ambition of two fourth-generation winegrowers pursuing California's potential for world-class Pinot Noir and Chardonnay. Inspired by Burgundy's great vineyards, they turned to the Pacific coast's rugged terrain, maritime climate, and varied soils to make wines prized for their perfume, poise, and sense of place.
Named for Research in Agriculture and Enology Naturally, RAEN places the vineyard at the center of its philosophy. Thoughtful farming, native fermentations, and a light hand in the cellar allow the brothers to translate the character of their coastal sites into wine. Their efforts have attracted international attention, including James Suckling's selection of the 2023 Royal St. Robert Pinot Noir as his No. 1 American Wine of 2025. RAEN now occupies a distinctive place in California fine wine, carrying forward the Mondavi family's ambitions on an entirely different stretch of coast.
History of RAEN
RAEN's story begins more than a century before its founding, with Cesare Mondavi's arrival in America from Italy in 1906. Alongside his wife Rosa, Cesare laid the foundations of a family wine business that would help transform Napa Valley. The Mondavis acquired Charles Krug Winery in 1943, and in 1966 Robert Mondavi established his namesake estate, becoming a central figure in California's emergence as a serious fine-wine region. His willingness to challenge convention, look abroad for inspiration, and invest in quality would influence generations of winemakers, including his grandsons Carlo and Dante.
Although the Mondavi name became synonymous with Napa Valley Cabernet Sauvignon, Pinot Noir also held an important place in the family's thinking. In the early 1970s, Carlo and Dante's father, Tim Mondavi, was among the California winemakers exploring the variety's possibilities, taking inspiration from Burgundy. Raised around the vineyards and cellars of Robert Mondavi Winery and Opus One, the brothers learned both the discipline of winemaking and the value of understanding individual sites. Their education extended beyond Napa, with Carlo studying in France and Italy and Dante pursuing studies in Switzerland and at the University of California, Davis.
A formative experience came in 2002, when the brothers accompanied their grandfather Robert to Burgundy, visiting renowned estates including Domaine de la Romanée-Conti. Robert wanted his grandsons to encounter the vineyards and wines that had informed his own ambitions decades earlier. The trip deepened their fascination with Pinot Noir and the relationship between soil, climate, and the finished wine. Burgundy was more than a stylistic model: it showed how one grape variety could reveal meaningful differences between neighboring parcels.
The family's course changed in 2004, when Robert Mondavi Winery was sold to Constellation Brands, ending the family's ownership of the estate. Robert, Tim, Marcia, and the next generation went on to establish Continuum Estate in 2005, pursuing Cabernet Sauvignon on Napa Valley's Pritchard Hill. Carlo and Dante contributed to the venture, but Pinot Noir kept drawing their attention westward. Years spent exploring California's coastal vineyards convinced them that western Sonoma's remote hills offered the long growing seasons and demanding conditions needed for the wines they envisioned.
In 2013, Carlo and Dante founded RAEN as an independent venture, selecting cool, elevated sites along the Sonoma Coast. Their inaugural vintage comprised three tiny Pinot Noir bottlings, each drawn from a different coastal vineyard to highlight its origins. When the wines debuted in 2014, individual cuvées averaged fewer than 100 cases, a measure of the project's intimate beginnings. Pronounced rain, RAEN's name also evokes the brothers' belief that great wine starts with the natural cycle of rainfall, soil, vine, and sunlight.
Over the next decade, RAEN grew from a small family project into a closely followed Sonoma Coast producer. The brothers broadened their work with coastal sites, introduced Chardonnay, and strengthened their commitment to organic and regenerative farming. In 2016, Carlo launched the Monarch Challenge, encouraging agricultural practices that support biodiversity and reduce reliance on herbicides. Recognition for the 2023 vintage brought the estate wider attention, but its underlying purpose remained the same: to explore how clearly Pinot Noir and Chardonnay could speak of the Pacific coast.
Terroir
Along Sonoma County's western edge, where redwood forests descend toward the Pacific, RAEN works with vineyards shaped by ocean winds, morning fog, and cool, extended growing seasons. The maritime influence slows sugar accumulation and allows Pinot Noir and Chardonnay to develop flavor while retaining the acidity that gives these wines their energy. Ripening here can be demanding, but the reward is fruit with fragrant detail, measured concentration, and the freshness needed to age gracefully.
RAEN's sites lie in two contrasting parts of the Sonoma Coast: Freestone-Occidental and Fort Ross-Seaview. Around Freestone-Occidental, vineyards overlooking Bodega Bay encounter thick morning fog followed by afternoon sunshine. Goldridge sandy loam and iron-rich Franciscan soils contribute to the area's varied growing conditions. Farther north, the ridges of Fort Ross-Seaview climb toward 1,000 feet above the Pacific, with some sites rising above the fog. More direct sunlight, persistent winds, and exposed slopes create a different balance of ripeness and structure.
The geology is just as varied as the climate. At Sea Field, vines grow in marine-derived soils and fractured rock associated with an ancient seabed. Elsewhere, shifts in slope, exposure, and soil depth change how vines access water and how fruit ripens. Those differences help explain the range of styles within RAEN's Pinot Noirs, from open, floral expressions to wines with darker fruit and firmer tannins. The Pacific is the common thread, but no two sites tell quite the same story.
The Vineyards of RAEN
RAEN works with approximately 38 acres of coastal vineyards devoted to Pinot Noir and Chardonnay. Carlo and Dante Mondavi approach the sites much as Burgundy's domaines approach their individual climats, looking for the qualities that separate one parcel from another rather than aiming for a uniform house style. Across Freestone-Occidental and Fort Ross-Seaview, differences in vine age, exposure, and planting density give the brothers a varied set of raw materials. The focus remains on small lots and wines that retain a clear connection to their origins.
Bodega Vineyard is a 1.8-acre Pinot Noir site overlooking Bodega Bay in Freestone-Occidental. Its steep, southwest-facing slopes sit around 600 feet above sea level, with dense meter-by-meter plantings that demand hand cultivation. Redwood trees, coastal oaks, and native vegetation surround the two small blocks. Just uphill, the upper estate block provides a foundation for Royal St. Robert, the Sonoma Coast cuvée honoring Robert Mondavi. Fruit from other carefully chosen coastal parcels contributes additional dimensions to that wine.
Farther north, Sea Field Vineyard occupies 4.8 acres on a remote Fort Ross-Seaview ridge roughly 1,000 feet above the ocean. The site is known for Pinot Noir grown in marine-influenced soils and fractured rock. Nearby, the 7.8-acre Pacific Rock Vineyard rises between 940 and 1,000 feet, with a southwest-facing exposure and persistent coastal winds. These neighboring vineyards yield different expressions: Sea Field tends toward perfume and delicacy, while Pacific Rock offers greater density and grip. Pacific Rock received its first vineyard-designated release with the 2024 vintage.
Chardonnay has its own foothold in RAEN's coastal portfolio. At Charles Ranch Vineyard in Fort Ross-Seaview, vines planted in 1981 grow around 1,200 feet above sea level. The mature Wente-clone plantings and naturally modest yields provide fruit with depth, texture, and acidity. Lady Marjorie takes a different approach, bringing together Chardonnay from selected Sonoma Coast sites in a cuvée named for the brothers' grandmother, Marjorie Mondavi. The contrast illustrates how RAEN uses both individual vineyards and thoughtful blending to explore the variety.
Farming is central to that work. RAEN emphasizes organic and regenerative practices intended to sustain soil health, native vegetation, and beneficial wildlife. Its Freestone-Occidental home estate has been certified organic since 2022, while the broader approach reflects the brothers' interest in reducing chemical inputs and strengthening the surrounding ecosystem. The objective is practical as well as philosophical: healthy, balanced vines give the cellar the best chance to work with fruit that needs little correction.
Winemaking
In the cellar, Carlo and Dante Mondavi work alongside winemaker Melanie McIntyre with a preference for restraint over intervention. Recent RAEN Pinot Noirs are fermented with 100% whole clusters, retaining stems that can add floral lift, spice, and a fine tannic framework. Fermentations begin with yeasts naturally present on the fruit rather than commercial inoculations. These choices demand careful attention to fruit and stem maturity, but they help produce wines with a fragrant, savory dimension that distinguishes RAEN's style.
After fermentation, the Pinot Noirs are gently pressed and aged primarily in neutral French oak for approximately 10 to 18 months, depending on the vintage. The restrained use of new wood keeps fruit, floral notes, and site character in the foreground. Chardonnay follows a different path: whole clusters are pressed before native fermentation in barrel, building texture without sacrificing brightness. RAEN generally avoids fining and filtration, seeking to carry the wines' natural detail through to bottling.
The approach may sound straightforward, but whole-cluster fermentation and low-intervention élevage leave little room to hide imperfect fruit. Harvest timing, gentle extraction, and barrel selection all matter. Rather than chasing weight or overt oak character, RAEN aims for wines that balance ripe fruit with tension, supple texture, and a lingering savory finish. The result is recognizably Californian in origin, yet guided by the same attention to site that first drew the brothers to Burgundy.
Wine Lineup
Royal St. Robert Pinot Noir
Named in honor of the brothers' grandfather, Robert Mondavi, Royal St. Robert is RAEN's signature Sonoma Coast Pinot Noir. Assembled from select coastal vineyards, including the estate's Freestone-Occidental holdings and distinguished Fort Ross-Seaview parcels, it offers a compelling introduction to the domaine's style. Expressive notes of wild strawberry, red cherry, rose petals, black tea, and coastal forest floor accompany a beautifully refined palate. The wine's combination of aromatic intensity, silky tannins, and vibrant acidity has established it as one of RAEN's most celebrated releases.
Bodega Vineyard Pinot Noir
Produced from a remarkable 1.8-acre vineyard overlooking Bodega Bay, Bodega represents one of RAEN's most distinctive single-vineyard expressions. Its densely planted, steeply sloping vines produce a Pinot Noir of exceptional aromatic complexity and concentration. Dark cherries, crushed raspberries, exotic spices, and floral notes emerge alongside a distinctive savory character. Structured yet remarkably elegant, Bodega captures the intensity and individuality of its remote Freestone-Occidental origins.
Sea Field Vineyard Pinot Noir
Perched approximately 1,000 feet above the Pacific Ocean in Fort Ross-Seaview, Sea Field is celebrated as RAEN's most elegant single-vineyard Pinot Noir. Rooted in ancient marine soils, the vines produce a beautifully lifted wine characterized by rose petals, wild strawberries, blood orange, white tea, and subtle coastal salinity. Its delicate texture, finely integrated tannins, and exceptional length offer a particularly graceful expression of the Sonoma Coast.
Pacific Rock Vineyard Pinot Noir
The newest addition to RAEN's single-vineyard collection, Pacific Rock debuted with the 2024 vintage. Located along a windswept Fort Ross-Seaview ridgeline, the vineyard produces a more powerful, structured expression of coastal Pinot Noir. Dark berries, wild herbs, rose petals, and earthy mineral notes define a wine of impressive concentration and depth. Its inaugural 2024 release earned 100 points from James Suckling, immediately establishing Pacific Rock as an important addition to RAEN's portfolio.
Lady Marjorie Chardonnay
Dedicated to the brothers' grandmother, Marjorie Mondavi, Lady Marjorie brings together carefully selected Chardonnay parcels from across the Sonoma Coast. The wine emphasizes freshness, aromatic clarity, and mineral-driven elegance, with expressive notes of lemon blossom, white peach, honeysuckle, crushed stone, and citrus zest. Native fermentation and restrained oak influence preserve its delicate character, delivering a beautifully balanced Chardonnay that captures the vitality of California's coastal vineyards.
Charles Ranch Vineyard Chardonnay
Sourced from Chardonnay vines planted in 1981 at approximately 1,200 feet in Fort Ross-Seaview, Charles Ranch represents one of RAEN's most compelling old-vine expressions. Its mature Wente-clone vines produce a wine of exceptional depth and texture, combining white flowers, lemon pith, stone fruit, and subtle brioche with pronounced mineral character. Richness and concentration are balanced by vibrant acidity, creating a sophisticated Chardonnay with remarkable length and aging potential.
Critical Acclaim & Prestige
RAEN's critical reputation has grown quickly for an estate founded in 2013. Reviewers including James Suckling and Antonio Galloni have praised the precision and individuality of its coastal wines, but the defining breakthrough came in 2025. James Suckling ranked the 2023 Royal St. Robert Pinot Noir his No. 1 American Wine of the Year and No. 2 wine worldwide. Scored 99 points, the bottling brought international attention to a project that had begun with just a handful of tiny Pinot Noir releases.
The 2024 vintage strengthened that standing. James Suckling awarded the inaugural Pacific Rock Vineyard Pinot Noir 100 points, with 99 points each for Royal St. Robert and Charles Ranch Chardonnay. Bodega Vineyard and Sea Field Pinot Noir received 98 points, while Lady Marjorie Chardonnay earned 97. The range of high scores across both varieties and multiple sites suggests a producer finding consistency without sacrificing the character of individual wines.
Those accolades also mark a shift in how California's finest wines are perceived. The Mondavi name became famous through Napa Cabernet Sauvignon, but Carlo and Dante are making their case with coastal Pinot Noir and Chardonnay, where fragrance, texture, and freshness matter as much as concentration. RAEN's rise is evidence that the family's ambition to compete on the world stage remains alive, even as the grapes, landscapes, and methods have changed.
Conclusion
Robert Mondavi helped convince the world that California could stand alongside Europe's great wine regions. His grandsons have taken that ambition west, to a colder and less forgiving coastline where Pinot Noir and Chardonnay reveal a different side of the state.
At RAEN, the legacy is not simply a famous surname. It is the willingness to explore new ground, trust the vineyard, and make wines that speak clearly of where they were grown.
