Founded in 1977 by Sandra MacIver with Merry Edwards as the inaugural winemaker, Matanzas Creek did more than launch a winery: it founded an AVA. The estate played a central role in securing Bennett Valley's official designation in 2003, and its Sauvignon Blanc helped define the category for a generation of California winemakers. Purchased by Jackson Family Wines in 2000, the winery continues to produce site-expressive wines from sustainably certified estate vineyards. The property is also famous for its lavender fields, a defining landmark of Bennett Valley.
Bennett Valley Merlot: the signature wine that made the appellation's reputation; black cherry, dark chocolate and a classic, balanced style.
Sonoma County Sauvignon Blanc: a nine-vineyard blend, individually harvested and fermented; bright, layered and a longtime benchmark.
Bennett Valley Chardonnay: firmly structured, with golden apple, pear and a cool-climate line of acidity.
Estate Red Blend, Bennett Valley: a Bordeaux-style blend led by Cabernet Sauvignon with Merlot and Malbec; ripe and structured.
Journey Red Blend: from the winery's Journey line, which also includes a Chardonnay, a Pinot Noir and a Sauvignon Blanc.
The estate's three acres of lavender are hand-cut and dried each year and sold at the winery as lavender products, and Matanzas Creek was among the first wineries to earn Certified California Sustainable status.
Matanzas Creek sits in a horseshoe-shaped pocket where Petaluma Gap winds meet Bennett Valley's volcanic hillsides, and the estate's Merlot was once considered the signature California expression of the variety. The property spans 300 acres of certified sustainable land, 55 planted to Merlot, Chardonnay, Sauvignon Blanc, and Pinot Noir. Winemaker Marcia Torres Forno farms meticulously and blends with restraint. The lavender fields visible from every tasting room vantage are the other landmark. Every visit is by reservation: the Estate Tasting, the Cellar Selection, or the Picnic & Bottle Service at a reserved table with your own picnic. Dogs are welcome at the picnic tables.

Marcia Torres Forno is the winemaker at Matanzas Creek, building on a Bennett Valley estate founded in 1977 and made famous by founding winemaker Merry Edwards's benchmark Sauvignon Blanc. Born in Chile and trained in agricultural engineering and enology at Catholic University in Santiago, with an MBA from Sonoma State, she honed her craft at Cardinale in Napa and Kendall-Jackson in Sonoma before taking the reins. Known for her command of aromatics, she harvests each block in phases and ferments in oak, concrete eggs, and stainless steel to layer texture into the winery's Sauvignon Blanc, Chardonnay, and Merlot. The estate, now part of Jackson Family Wines, is certified sustainable.

Sandra MacIver founded Matanzas Creek in 1977 with her husband Bill, establishing a trailblazing winery on the site of a former Bennett Valley dairy. With Merry Edwards as her founding winemaker, MacIver set out to make world-class, terroir-driven wines and quickly earned acclaim for benchmark Sauvignon Blanc and Merlot. In 1996 Wine Spectator named her one of the twenty most influential people in the modern wine industry. Her vision helped define the Bennett Valley growing region and shaped a winery, now part of Jackson Family Wines, still known for its lavender gardens and aromatic whites.
