Rick Quinn and David Nichols started as neighbors, became friends, and eventually joined forces to fulfill their shared dream of creating a winemaking legacy in Paso Robles.

In 1997, Rick and David began planting vineyards, and by 1999, they established their family winery in the coastal mountains of the Willow Creek District. They chose the name Opolo to honor Quinn's Serbian heritage, referencing a rosé-style wine native to the Dalmatian Coast.

Although the modern winemaking era in Paso Robles was just beginning, Rick and David recognized the region’s immense potential. They focused on Zinfandel, a heritage grape of Paso Robles, as well as Bordeaux and Rhône varieties that would come to define the area's reputation.

Since then, Opolo has become a cornerstone of the Paso Robles experience, known for its widely acclaimed estate wines, warm hospitality, and legendary wine club. Today, Opolo offers a diverse selection of wines, including the iconic Mountain Zinfandel, limited-release reserves, and vineyard designates. Visitors are invited to explore the world of Opolo at their tasting room.

Caymus Vineyards is located in the center of the Napa Valley. Primary production is Cabernet Sauvignon grown on low-fertility soils on both the valley floor and the mountains that surround the valley. Attention to viticulture details, some dry farming, high-density plantings (with some blocks spaced as close as meter x meter), thinning of the yield, along with healthy vines and harvesting at an elevated degree of ripeness – all of these elements produce a unique and singular style of Cabernet.

While the wine has sufficient tannins and structure for long-term bottle aging, Caymus Cabernet is dark and concentrated, with ripe, luxurious, fruit-driven softness that shows from the day of release.

In addition, Caymus produces a smaller amount of Special Selection Cabernet. A limited bottling of Napa Valley Zinfandel honors winery co-founder Charlie Wagner Sr., for whom it was a favorite. All a part of Wagner Family of Wines.

The Historic Galleano Winery was founded in 1927 by Domenico Galleano. Remarkably, the winery complex has remained largely unchanged to this day.

Galleano Winery is notable for being the last remaining bonded, Prohibition-era winery still owned and operated by its founding family at its original location in the Cucamonga Valley. The Galleano family takes great pride in the fact that the Cantu-Galleano Ranch complex is listed as a landmark on both the California and National Register of Historic Places.

Located in Mira Loma’s Wineville area, Galleano Winery retains much of its 1927 charm. It sits at the southern fringe of the Cucamonga Valley, a region made famous for winegrowing by Secondo Guasti, who, like Domenico, hailed from northern Italy’s Piedmont region. The name "Cucamonga" translates to "sandy place," aptly describing the alluvial plain that descends from the eastern slopes of the San Gabriel Mountains.

During the 1940s, the Cucamonga Valley boasted more than 45,000 acres dedicated to vineyards and approximately 60 wineries, showcasing the area’s rich viticultural history.
