Our winemaking operations are led by Mike Sinor and Nathan Carlson, both veteran Edna Valley winemakers with longtime personal connections to the estate.

Mike’s first wine industry job was at the Lawrence estate, now home to Center of Effort. Over the past 15 years, he has dedicated himself to the mastery of Burgundian varietals, earning some of our region’s highest ratings along the way. His continual quest for knowledge has taken him to France several times, where he gained immeasurable insights from some of Burgundy’s top producers. At Center of Effort, Mike guides the stylistic direction of our wines.

Nathan’s winemaking experience in the Edna Valley spans more than 12 years. He has also made Pinot Noir in Santa Barbara County, Carneros, the Sonoma Coast and Oregon’s Dundee Hills. His work with wine industry technical leaders has forged close ties with winemakers around the world. At Center of Effort, Nathan oversees our winemaking operations and manages the estate.

Mike and Nathan became friends after frequently crossing paths in the Edna Valley. They now come full circle, back to our estate. Their expertise is instrumental in achieving the rigorous standards of quality and artistry that we demand in our wines.


The origins of the estate date back to 1978, when it was established by Jim Lawrence, who was one of the first vintners to grasp the potential of the Edna Valley. In time, the Lawrence estate became an epicenter of the local wine community, serving as a touchstone for some of the region’s brightest winemaking talents, including our own winemakers.

Today, this estate is the foundation of Center of Effort, where the guiding forces of skillful cultivation, artful winemaking and a passion for excellence come together—and ultimately create the “magic”—in the bottle.

Practices & Techniques

We are steadfast in our commitment to maximizing the potential of our vineyard, as achieved through skillful and sustainable cultivation.

From the start, we have entrusted Kevin Wilkinson of Coastal Vineyard Care with the management and progressive redevelopment of our estate vineyard. He and his team care take several top vineyard estates in Edna Valley and Paso Robles including the Stone Corral Vineyard, immediately adjacent to our own. His experience in our local terroir has brought detailed practical knowledge of the soil and climate conditions specific to our site.

Together, we pursue an unyielding standard of quality in the vineyard. Only the finest vineyard blocks are designated for the production of Center of Effort wines. These blocks are farmed on a per-vine basis, accounting for everything from sun exposure to soil variables.

Natural cover crops, real-time moisture monitoring, minimal inputs and other sustainable practices are also essential to our vision of respectful vineyard stewardship.

Estate Vineyards / AVA

Our estate vineyard is pitched along south-facing slopes in the western Edna Valley, just 4.5 miles from the Pacific shoreline.

The vineyard unfolds along an uplifted ancient dune. The soil is different here—rocky and sandy, in contrast to the thicker clay soils found elsewhere in the valley. The vines achieve natural balance in this ground, with limited vigor and low yields. The lean, sandy soil is ultimately a differentiating factor in our wines, expressing itself with sleek complexity.

The Edna Valley is a transverse coastal valley that runs from west to east, a rare orientation that invites morning fog and afternoon marine breezes. Such climatic conditions are optimal for Burgundian varietals, fostering a long maturation period for the development of exquisite structure and flavor.

The interplay of climate and soil ultimately exerts a signature sense of place in our wines.
