Cucamonga Valley Wineries

Commercial wine production in the Cucamonga Valley began in 1839 when Tiburcio Tapia, the Mexican-era owner of Rancho Cucamonga, planted the first commercial vineyard on his land grant. Tapia's vineyards were initially planted with Mission grapes — the variety the Spanish missions had used for sacramental wine since the 1700s — but were quickly expanded to include European varieties as additional cuttings became available through Pacific trade.

After California's transition to American territory in 1848 and statehood in 1850, the Cucamonga Valley wine industry expanded rapidly. By the 1870s and 1880s, the valley was producing both table wines for the growing California domestic market and bulk wine that was shipped via the Southern Pacific Railroad to East Coast markets. Several of the largest wine estates in 19th-century Southern California — including the Cucamonga Vineyard Company, which at its peak held over 1,000 acres — were located in the valley.

The pre-Prohibition era was the valley's first great boom. Zinfandel was planted extensively from the 1870s onward, drawing on cuttings imported from European sources and becoming the dominant red variety across the region. Some of those original Zinfandel plantings survive today — a small number of producers source fruit from vines that have been continuously productive for 130 to 140 years, making them among the oldest commercial vines in California.

Prohibition (1920-1933) damaged the Cucamonga Valley wine industry but did not destroy it. Many local wineries survived by producing sacramental wine (legal under the Volstead Act for use by religious institutions) and by selling fresh grapes to home winemakers — a legal practice that became remarkably profitable as East Coast home winemaking exploded during the Prohibition years. The valley's grape acreage actually increased during portions of Prohibition because of the home-winemaking grape market.

Repeal in 1933 allowed legal commercial wine production to resume, and the valley experienced a substantial recovery through the 1930s, 1940s, and into the postwar period. But the longer-term threat was suburbanization. Beginning in the 1950s and accelerating through the 1960s, 1970s, and 1980s, Inland Empire population growth converted vineyard land into housing developments, shopping centers, freeways, and industrial parks. By 2000, the valley's vineyard acreage had dropped from its early-century peak of over 35,000 acres to a few hundred — a roughly 99 percent decline.

The 1995 AVA designation marked the beginning of a deliberate preservation and revival effort. Several historic wineries that had survived the suburbanization era — Galleano Winery, Filippi Winery, Joseph Filippi Winery — formalized their commitments to maintaining production. A small number of newer boutique producers entered the valley in the 2000s and 2010s. Today the valley is genuinely small but stable, with perhaps a dozen working tasting rooms producing wines from both estate-grown fruit and grapes sourced from the few remaining historic vineyards.

Galleano Winery is the largest and most historically significant operation currently in the valley. Founded in 1933 immediately after Repeal and continuously operated by the Galleano family since, the winery sources fruit from some of the valley's oldest Zinfandel vineyards (several plantings date to the 1880s) and produces a substantial range of red and white wines under multiple labels. The tasting room is open most days and offers tasting flights at modest prices. Galleano is also a California Historical Landmark and the visitor experience includes a free informal tour of the historic winery buildings.

Joseph Filippi Winery — a separate operation from Filippi Winery despite the similar names — is another long-established Cucamonga Valley producer with a substantial tasting room and event space. The winery has been operated by the Filippi family for multiple generations and offers regular tastings of Zinfandel, Cabernet Sauvignon, and various Mediterranean varieties that thrive in the warm Inland Empire climate.

Several smaller boutique producers — including newer operations that have entered the valley since the 2000s — round out the available tasting room options. Most have limited hours (typically Thursday through Sunday afternoons) and small production runs, but their wines are often available only through direct tasting-room purchases and represent some of the more interesting expressions of Cucamonga Valley terroir. The Rancho Cucamonga Visitor Center and the 1937 Route 66 Service Station can both provide current lists of operating tasting rooms.

The natural Rancho Cucamonga heritage day combines wine country with the Sycamore Inn and the 1937 Service Station — three sites that capture the area's three overlapping historical eras. The classic plan: 1937 Service Station mid-morning (45 minutes), Sycamore Inn for lunch or a midday visit (90 minutes including a meal), and one or two wineries in the afternoon (2 to 3 hours). The total itinerary runs 4 to 6 hours depending on pace.

For visitors who want to focus on wine country specifically, plan a full half-day of winery visits. Most tasting rooms charge $15 to $30 per tasting flight; appointments are generally not required at the larger wineries (Galleano, Joseph Filippi) but are appreciated at the smaller boutique producers. Driving between wineries is straightforward — most are within 10 minutes of one another in the valley — but visitors should plan for a designated driver or use rideshare given the tasting volume.

For visitors continuing east toward San Bernardino (15 miles east) or west toward Glendora (5 miles west) and Pasadena (20 miles west) along Route 66, the Cucamonga Valley wineries fit naturally into a broader San Bernardino County or San Gabriel Valley Route 66 itinerary. The historic Route 66 alignment along Foothill Boulevard passes within a few miles of most of the valley's tasting rooms, making the wine country detour a relatively minor diversion from the main route.
