Mariposa Ranch

Mariposa Ranch is a family run ranch with a mission to bring great tasting, healthy, sustainable beef to our customers.

Seth and Mica Nitschke, family ranchers in Central California, founded Mariposa Ranch, formerly Open Space Meats, in 2006 after Seth had spent many years in the conventional cattle business. After a time spent on a small grass-fed beef farm in Western Australia, Seth decided to bring the cattle care and harvesting methods to the United States.

Mariposa Ranch works with great respect for the environment and with the cattle in their care. Their cattle are hormone, and antibiotic free. The ranch also doesn’t use herbicides, pesticides or commercial fertilizers on their pastures. All of the cattle are 100% grass-fed, pasture raised, and pasture finished.
