Thornhill Companies

The Thornhill Companies represents the umbrella brand of one of California’s premier winegrowing families. The Miller family has farmed California soil for five generations and has earned respect for its agricultural influence since the late 1800’s. Stephen Miller leads the company’s efforts, along with his sons Marshall Miller, VP of Operations and Finance and Nicholas Miller, VP of Sales and Marketing.

Included within the The Thornhill Companies are the family’s three estate vineyards: Bien Nacido Vineyards, Solomon Hills Vineyards, and French Camp Vineyards; Central Coast Wine Services and Paso Robles Wine Services (which offer bulk wine, custom crush, winery services, bottling, and case goods storage); and the family’s private label wine company: Turn Key Wine Brands.

Using this vertically integrated business model, the Miller family is able to fulfill each customer’s wine needs through The Thornhill Company’s various entities, providing wine production services from vine to bottle for their negociant clients, private label customers, and custom crush wineries.


“We hope to provide all aspects of service to our customers,” explains family spokesperson, Nicholas Miller. “We grow and sell fruit. We offer bulk wine and wine storage. We own and operate our own bottling line and have considerable warehousing capabilities in both Santa Maria and Paso Robles.”

The Thornhill Companies has firmly established itself as an industry leader. Through their thoughtful approach to farming and pioneering wine industry efforts, the Miller family continues its legacy of agricultural integrity and innovation year after year.
