American winemakers are bringing a new level of sophistication to sparkling wine, with bottles aged for five to nearly 20 years offering greater complexity, richer textures and flavors that rival some of Champagne’s finest offerings.

Although the United States has long been recognized for producing quality sparkling wines, extended aging is emerging as a growing category. These wines spend years resting on their lees after secondary fermentation, allowing them to develop deeper flavors, finer textures and greater complexity.

Producers in California and Oregon are leading the movement, combining traditional winemaking techniques with the distinctive characteristics of their local vineyards.

Domaine Carneros Brings Extended Aging to Napa Valley

Founded in 1987 by the family behind Champagne’s Taittinger, Domaine Carneros has become a prominent name in American sparkling wine. Its flagship Le Rêve Blanc de Blancs is made from Chardonnay grown in California’s Carneros region.

The winery’s 2018 vintage spent seven years aging on its lees, a process that contributes to its creamy texture and layered flavor profile. The wine combines notes of citrus, lychee and Bartlett pear with the richer characteristics associated with extended maturation, including brioche, shortbread and crème fraîche.

Domaine Carneros CEO Remi Cohen explains that prolonged lees aging allows yeast cells to break down gradually, releasing compounds that enhance the wine’s flavor and texture.

The cool, consistent conditions of the 2018 growing season also helped preserve acidity while encouraging gradual fruit development, giving the wine a balance of freshness and richness.

Schramsberg Showcases Nearly Two Decades of Aging

Further north in Napa Valley, Schramsberg Vineyards has been producing sparkling wine since Jack and Jamie Davies acquired the historic estate in 1965.

Their son, Hugh Davies, who took over leadership in 2005 after years of working at the winery, says the producer has continually sought to improve the quality of its wines.

One of its latest releases, the 2007 Late Disgorged J. Schram, blends Chardonnay and Pinot Noir sourced from vineyards across Napa Valley. The wine reflects a growing-season widely regarded as one of the decade’s strongest.

After nearly 20 years of aging, the bottling demonstrates how extended maturation can create greater richness and complexity. Barrel fermentation and malolactic fermentation in the base blend contribute to its fuller character, while the naturally high acidity associated with California’s cooler North Coast vineyards provides freshness and a long finish.

Davies also points to the wine’s enduring fruit character as an expression of the region’s Pacific-influenced terroir.

Oregon Producers Explore the Benefits of Patience

Oregon is also establishing itself as a destination for premium sparkling wine, building on its reputation for Chardonnay and Pinot Noir.

Domaine Willamette’s 2017 Extended Tirage Brut, its first long-aged release, was developed to explore how additional time on the lees could enhance texture, depth and integration.

Director of winemaking and vineyards Terry Culton says seven years of aging allows the wine to evolve beyond the bright fruit and freshness associated with younger sparkling wines. The result is a more developed expression of traditional-method winemaking that retains the character of the Willamette Valley.

Rather than attempting to imitate Champagne, the winery aims to apply the region’s established standards of craftsmanship while highlighting Oregon’s cool climate and distinctive vineyard conditions.

Gran Moraine is pursuing a similar approach with its Yamhill-Carlton Extended Tirage Brut Rosé NV, which spends six years aging on its lees.

Winemaker Shane Moore says the grapes are harvested to preserve acidity and freshness, providing the structure needed for prolonged aging. Over time, the wine develops more intricate flavors and finer bubbles as the prominence of fresh fruit gradually gives way to additional layers of character.

Extended-Aged Sparkling Wines Find Their Place at the Table

Beyond their complexity, these wines are gaining recognition for their versatility with food.

Arthur Hon, a sommelier at New York City wine bar Lei, favors Domaine Carneros 2000 Le Rêve Late Disgorged Blanc de Blancs for its velvety texture and combination of salted caramel-like apple, toasted almond and citrus notes.

He recommends pairing the wine with roast chicken or pork Milanese, noting that the dishes’ savory qualities complement the sparkling wine’s fruit and umami characteristics.

At Jory at the Allison Inn & Spa in Newberg, Oregon, wine director Elaine Kim pairs Gran Moraine Extended Tirage Brut Rosé NV with wagyu steak frites. Its acidity and layered flavors offer a refreshing counterpoint to the richness of the dish.

As American producers continue experimenting with longer aging periods, the category is gaining a clearer identity of its own. Rather than simply reproducing the style of French Champagne, these wineries are using traditional techniques to showcase the distinctive qualities of California and Oregon.

The result is a collection of sophisticated sparkling wines that demonstrate how time, craftsmanship and regional character can transform American bubbly into a serious contender in the world of fine wine.
