Saxum Vineyards

SAX-um

Saxum Vineyards was founded in 2000 by Justin Smith on the James Berry Vineyard in Paso Robles' Willow Creek District, which his parents Terry and Carolyn Smith had planted in 1981 on steep calcareous limestone hillsides. Saxum produces Rhône-style blends (predominantly Grenache, Syrah, Mourvèdre with Counoise and other supporting varieties) plus single-block bottlings; the 2007 James Berry Vineyard was named Wine Spectator's Wine of the Year in 2010, an unprecedented honor for a Paso Robles wine. Annual production is intentionally limited and the mailing list is closed.

📜Origins and Founding

Justin Smith grew up on the James Berry Vineyard, which his parents Terry and Carolyn Smith had purchased and planted in 1981 on steep calcareous limestone hillsides in what would become the Willow Creek District AVA west of Paso Robles. The Smith family sold fruit to other producers through the 1980s and 1990s. After studying viticulture and enology at Cal Poly San Luis Obispo and working harvests in Australia and France, Justin returned home in the late 1990s convinced that the family vineyard could produce world-class Rhône-style wines under its own label. He founded Saxum (Latin for 'stone,' a reference to the vineyard's limestone soils) in 2000, with the inaugural commercial vintage that year. The wines drew immediate attention from California critics, and within a decade Saxum was widely considered the most prestigious Paso Robles Rhône-style estate. The 2010 Wine Spectator Wine of the Year designation for the 2007 James Berry Vineyard cemented that reputation globally.

  • Studied at Cal Poly San Luis Obispo; harvest experience in Australia and France before founding Saxum 2000
  • Saxum (Latin for 'stone') named for the limestone hillside soils of the James Berry Vineyard
  • 2010 Wine Spectator Wine of the Year for the 2007 James Berry Vineyard cemented Saxum as Paso Robles' most prestigious Rhône-style estate

🎯Why It Matters

Saxum's 2010 Wine Spectator Wine of the Year for the 2007 James Berry Vineyard was a landmark moment for Paso Robles and for American Rhône-style wines broadly. No Paso Robles wine had ever held the #1 position in Wine Spectator's annual ranking, and the recognition validated decades of Rhône Rangers Movement investment in the AVA by Tablas Creek, Booker, L'Aventure, and others. Saxum's stylistic combination - Justin Smith's emphasis on whole-cluster fermentation, blending traditions inherited from Châteauneuf-du-Pape, and the unusual concentration of the steep limestone James Berry site - demonstrated that California Rhône wines could achieve a level of distinction that paralleled Châteauneuf and Hermitage. The Saxum model influenced a generation of Paso Robles Rhône-style producers and shifted critical attention toward the AVA's western limestone hillside terroir.

🍷Style and Winemaking Approach

Justin Smith's winemaking philosophy emphasizes blending traditions inherited from Châteauneuf-du-Pape combined with whole-cluster fermentation and minimal intervention. Saxum's reds typically combine Grenache (the foundational variety), Mourvèdre (for structure and dark fruit), Syrah (for color and complexity), and supporting varieties (Counoise, Tannat, Petite Sirah, Cinsault). Whole-cluster percentages vary by block and vintage, typically running 30 to 70 percent. Fermentation is in small open-top tanks with native yeasts. Aging is in French oak (typically 25 to 40 percent new) for 18 to 22 months - substantial barrel time for the structure of the wines. Bottling is unfined and unfiltered. The wines display dense black fruit, savory herbal lift, structured tannins, and substantial alcohol (typically 14.5 to 15.5 percent), with substantial cellaring potential (10 to 20 years).

  • Blending traditions inherited from Châteauneuf-du-Pape: Grenache foundational + Mourvèdre + Syrah + supporting varieties
  • Whole-cluster fermentation 30-70% by block and vintage; native yeast in small open-top tanks
  • 25-40% new French oak for 18-22 months barrel aging; bottled unfined and unfiltered
  • Dense black fruit + savory herbal lift + structured tannins; alcohols 14.5-15.5%; 10-20 year cellaring potential

🏆Landmark Achievements

Justin Smith was named Winemaker of the Year by Food and Wine Magazine in 2010 and inducted into the Vintners Hall of Fame at the CIA Greystone in 2019. The 2007 James Berry Vineyard's Wine Spectator Wine of the Year designation in 2010 was a singular career honor; the 2008 vintage of the same wine was ranked #4 in Wine Spectator's Top 100 the following year. Multiple Saxum bottlings have scored 95 to 99 points across Wine Advocate, Wine Spectator, and Wine Enthusiast over the past two decades. Saxum's commercial success - closed mailing list, long wait times, secondary-market premiums - rivals the most prestigious Burgundy and California Pinot Noir estates. The estate's recognition has extended to broader Paso Robles recognition: subsequent prestige projects in the AVA have benefited from the validation Saxum's success represents.

🍇Vineyards and Sources

The James Berry Vineyard, planted 1981 by Terry and Carolyn Smith, is Saxum's foundational source. The vineyard occupies approximately 30 acres on steep calcareous limestone hillsides in the Willow Creek District, with elevations of approximately 1,300 to 1,600 feet and slopes up to 30 percent grade. Soils are predominantly calcareous shale and limestone derived from the Monterey Formation, with very thin topsoil. The vineyard is planted to Grenache, Mourvèdre, Syrah, Counoise, Tannat, Petite Sirah, Cinsault, and other Rhône varieties, organized into small designated blocks that source the single-block bottlings (Bone Rock, Rocket Block, Heart Stone). Adjacent properties in the Willow Creek District provide additional fruit for selected cuvées. Farming is non-organic but follows sustainable practices, with substantial canopy management to limit yields on the steep hillside.
