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.

In 1987, Jim Summers acquired a 28-acre vineyard nestled in Knights Valley, a region located northwest of Calistoga between Mount St. Helena and the Alexander Valley. At the time, the property was predominantly planted with Merlot grapes, established 30 years earlier by Dan Duckhorn, along with some Muscat Canelli. The inaugural vintage of Summers Ranch Reserve Merlot was produced in 1992, yielding 900 cases. Today, the estate also produces Petite Sirah from the Knights Valley vineyard. Known for its warm climate, volcanic soils, and proximity to Napa Valley, Knights Valley has recently garnered increased attention for its Bordeaux varietals.

In 1996, Summers expanded their vineyard holdings by acquiring 25 acres at the intersection of Highway 128 and Tubbs Lane in Napa Valley. This property, now known as Summers Estate Wines, is home to the Villa Andriana Vineyard, named in honor of their daughter. While the estate has been fully revitalized to maximize its potential, the 40-year-old Zinfandel vines are meticulously preserved. The winery and tasting room, surrounded by over 22 acres of Zinfandel, Charbono, and Cabernet Sauvignon vines, strike a perfect balance between pleasure and productivity.

Summers' signature wine is the distinctive Charbono, a varietal believed to be an early Italian adaptation of Charbonneau, a French grape. Some argue it is closely related to the Dolcetto variety, which is commonly grown in northern Italy. The Charbono vine produces large berries that create a deeply colored red wine, known for its rich fruit flavors and low tannin content when subjected to extended skin contact during fermentation.

The Summers Estate, with its scenic vineyard views in Calistoga, California, stands as a testament to the region's rich winemaking heritage.

When Matt and Maureen Trevisan founded Linne Calodo in 1998, they played a pivotal role in ushering in the modern wine era in Paso Robles. By the early 2000s, Paso Robles had transformed from an unproven wine region to an unstoppable force, thanks in large part to Rhône variety blends that garnered widespread critical acclaim. Linne Calodo was at the heart of this movement, and the rest is history.

This passion for the unconventional endures at Linne Calodo. The defining characteristic of all their wines can be encapsulated in one word: intentional. Matt Trevisan is far from an absentee winery owner; he is the farmer, winemaker, cover crop sower, fix-it man, amateur electrician, and sheep herder. Every Linne Calodo wine is meticulously guided from the field to the bottle under his dedicated care.
