About Us


Our Winery is situated under the watchful eye of the Topa Topa Mountain range in the Upper Ojai Valley, surrounded by ancient oaks and majestic redwoods. Owner Lauro Guerra built the winery to pursue his passion for viticulture and wine and to showcase exceptional wines made from grapes grown in the Ojai Valley Region.

The first estate vines were planted in 2009, with varietals selected based on the region’s unique climate and soil, after extensive research and analysis. Some of the plantings brought new varietals to the Ojai region, such as Barbera, Tempranillo, Carmenere and Touriga Nacionale. Others have long thrived in the region, including Syrah, Grenache and Viognier.

In addition to estate grown varietals, we are now producing high quality wines using grapes grown on neighboring farms, as well as grapes sourced from neighboring Santa Barbara county. We select only the highest quality grapes, grown on sustainably farmed vineyards, managed by growers who allow us to maintain careful control of the farming practices and techniques. We regularly visit the vineyards during the growing season to ensure that the highest quality standards are met, and carefully taste and measure for ripeness to determine optimal picking dates.

All of our wine is produced using techniques designed to reveal the flavors inherent in each varietal, as developed by the unique climate and terroir of our vineyards and then are aged in a mix of old and new French oak barrels. We carefully monitor the aging process and, when the wine is ready, bottle it under strict standards. The wine is then further aged until it is ready for your enjoyment.

 Our Winemaker

Winemaker Dominic O’Reilly’s winemaking career began at Owen Roe, his family’s winery, which has facilities in Washington and Oregon. He worked his way quickly from cellar-rat to management, gaining many skills in this fast-paced and competitive industry. Dominic developed a deep-rooted passion for the art of making and tasting wines, and soon began honing skills towards terroir-driven and European influenced styles.

Having begun his education in wine at an early age, Dominic chose to study Philosophy and Literature rather than pursue a degree in enology. After college, he began a life-changing role at the Ojai Vineyard in 2010, where he fell in love with the terroir and regions of Southern California and decided to devote his career to understanding it. Working closely with Adam Tolmach at the Ojai Vineyard, Dominic further refined his skills and style. In 2014, after a year of consulting, Dominic accepted the position of head winemaker for Topa Mountain Winery. Dominic has also broadened his experience with harvests in Australia at Killikanoon Winery, located in the Clare Valley, as well as Isabel Estate in Marlborough, New Zealand. He continues to consult for wineries and vineyards both locally and internationally.

Dominic has taken full advantage of the many microclimates spread across Santa Barbara County and Ojai. With his wines, he has been able to achieve complexity, marrying a balanced and refreshing style with the fruit and flavor evocative of our warmer Southern California climate.
