A revolution is happening in Sauvignon Blanc, driven by winemakers like Rebekah Wineburg who are demonstrating the potential of this white variety, says senior editor MaryAnn Worobiec. “She is the ultimate double threat. Not only does she make beautiful, elegant, Bordeaux-style reds, but she’s also making some of the best Sauvignon Blanc coming out of California.”
Wineburg, who grew up in Washington, D.C., was inspired at age 16 to become a winemaker during a family vacation stop in Napa Valley. “Listening to the tour guide talk about winemaking, it struck me that wine is magical”—a combination of art and science that transforms grapes into something that tells the story of a place and time. “I wanted to be a part of that.”
After college, Wineburg studied viticulture and enology at the University of California, Davis—with some help from the Wine Spectator Scholarship Foundation—then did stints at wineries in New Zealand, Australia, Oregon and California before joining Quintessa in Napa Valley in 2015.
In 1989, when Agustin and Valeria Huneeus founded Quintessa in the Rutherford AVA, their vision was clear: Quintessa is a place. Tucked between the Vaca Mountains and the Napa River and surrounded by diverse woodlands, the small vineyard blocks were devoted to Cabernet Sauvignon and tiny amounts of other Bordeaux varieties for a red blend.
Over a decade later, the Huneeus family wanted to add a white wine. “They chose Sauvignon Blanc because of its ability to be transparent to terroir,” said Wineburg. “At that time, Napa Sauvignon Blancs tended to fall into two camps. They could either be fresh and simple or heavily oaked. … But [they] wanted something different, something with more concentration, more layers.”
Illumination is built on three principles, says Wineburg: “First, that great wine speaks of place. Secondly, that expression of place is only achieved through thoughtful farming practices, and finally, that the winemaking practices are to support the expression of place.”
Since its first vintages, Illumination has evolved and been refined. “Blending is the key here,” said Wineburg: blending of varieties, vineyards and fermentation vessels, each chosen to accentuate the character of a vine parcel. Working with all these components allows her to craft a white with layers of complexity.
The Sauvignon Blanc in the blend contributes bright acidity and citrus flavors, while the Sauvignon Blanc Musqué clone brings floral and fruit aromatics, and Sémillon adds weight and viscosity. Wineburg relies on native yeast for fermentation and uses bâtonnage to develop texture while maintaining acidity.
The core of Illumination is the Quintessa estate, farmed organically since its founding and biodynamically for the past 20 years. Estate fruit is joined by grapes from southern Napa Valley and Sonoma’s Bennett Valley, plus old-vine Sémillon from Calistoga, all farmed following similar principles. “It’s only with fertile soil, healthy agriculture and more life in the soil that you get distinctive character in wine,” she says.
Seven different types of fermentation vessels were used in crafting the 2023 vintage, Wineburg explained: concrete eggs to bring out minerality, French oak barrels for creaminess and weight, French acacia wood barrels that emphasize fruit and floral character, neutral oak barriques and cigar-shaped barrels for purity of fruit and roundness, stainless steel barrels for linear acidity and pithiness, and new in 2023, ceramic amphorae to emphasize freshness.
Ample winter rainfall and a mild growing season marked the 2023 vintage, allowing for a long harvest and slow, even development of flavors. The resulting Quintessa Sauvignon Blanc Napa-Sonoma Counties Illumination 2023 (95 points, $60) is fresh and expressive with juicy, vibrant acidity and a compelling texture, says Wineburg. “This is really what makes Illumination stand out—its texture, minerality and sense of balance.” Enjoyable now, this white is also extremely ageable. Says Wineburg, “Illumination embodies everything that I think is most important in wine.”
