True Grass Farms
We are a family-owned and operated farm located three miles east of the Pacific coast in northwestern Marin county. We belong to the Estero Americano watershed where each day we dedicate ourselves to the land, to our community and to the future of this ecosystem.

We provide wholesome food grown and raised on healthy soil. Beyond organic, we are part of your bioregional food source. We grow grass. We produce grass-fed and finished beef, pastured Guinea and Blackworth hogs, as well as cage-free heritage fowl and eggs.

Our mission depends upon cultivating direct relationships with you, our friends, neighbors and loyal customers.

Farm Tours:

At True Grass Farms, we grow relationships around food. That’s why each month we invite you to join us here at the ranch for our farm tour and artisanal lunches. Learn where your food comes from, meet the piglets, walk the pastures and then join us for a farm-fresh lunch showcasing all the ingredients we grow and raise right here at our ranch in Marin County.

Community Supported Agriculture (CSA):

Throughout the year we offer California Kobe Wagyu beef, three different breeds of pastured-pork, free-range chicken,
rabbit and duck through our CSA. Each month, for your three month subscription, this assortment will more than satisfy two persons four meals of prime meats. For example, a box might contain 2 one-pound packages of ground sirloin and chuck, 2 filet mignons, 1 tender flank steak for two and a London broil for three people, plus a selection of our own True Grass Farms recipes.

The total cost for all this is $50 per month.
