Cline Family Cellars is a winery in California's Sonoma Valley that was founded by Fred Cline in 1982 in Oakley.

The estate's first wines were made from very old vines of Mourvèdre, Zinfandel and Carignan, the oldest of which had been planted in the 1880s.

Today, Oakley's vines are among the oldest and rarest in California and some are more than 100 years old. This vineyard continues to offer very beautiful wines made from these grape varieties planted on sandy soils with very deep roots of the vine and an ideal climate with warm temperatures during the day and cool at night.

In 1989, Fred Cline acquired 140 hectares in Carneros and set up his cellars there. A pioneer of Rhône grape varieties in the United States, he began planting Syrah, Viognier, Marsanne and Roussanne, then more classic grape varieties such as Pinot Noir, Merlot, and Chardonnay. The Carneros vineyard also benefits from very favourable conditions due to the influence of the ocean wind and shallow clay soils that produce small, tightly packed bunches.

The Petaluma Gap vineyard (Sonoma Coast) is also influenced by the Pacific Ocean on soils that are very suitable for Pinot Noir.

Cline Family Cellars is a certified sustainable winery by the State of California.
