The Vineyards at Marsh Creek in the San Francisco Bay Area is comprised of 37 acres of red wine grapes on the hillsides east of Mount Diablo. The initial plantings in 2006 consisted of Syrah, Petite Sirah, Montepulciano, Mourvedre, and Aglianico. Cabernet Sauvignon was planted in 2017. The vineyards are maintained by Vista Diablo, a local vineyard management company.

In 2005 Shea Homes began to develop Trilogy at the Vineyards, their new over 55 gated community in Brentwood, CA. UC Davis School of Viticulture and Enology evaluated the soil, climate, and geography of the community and developed planting recommendations. Shea negotiated with the city of Brentwood to allow Shea Homes to develop green space within the development by planting vines on land owned by the city but maintained by Trilogy as park space. In 2006 vines were then planted in accordance with the UC Davis Report. The Vineyards at Marsh Creek were born. In 2019, the Vineyards at Marsh Creek Homeowners Association assumed total control of the vineyards offering the grapes for sale. At the same time Estate Crush, a bonded winery in Lodi, CA, was hired to produce wine under the Vineyards at Marsh Creek label. In 2020 VMC obtained its own ABC license and now produces its wine under an Alternate Proprietorship arrangement with Estate Crush in their Lodi winery.

A small portion of the grapes are also used by a group of interested homeowners to make wine under the Amici Winemaking Club. They have done so from 2009 to 2014 and then from 2018 to present.

The community is very proud of its vineyards, both for the aesthetics they provide as well as for the sustainably farmed grapes they produce for commercial wineries.
