The producer
Why it matters.
The current supply relationship between Stemple Creek Ranch and State Bird Provisions and Chez Panisse traces grass-fed beef to Tomales, California, United States, with regenerative agriculture recorded in the producer profile.
The origin.
The Poncia family has stewarded land near Tomales for four generations. Loren and Lisa Poncia reshaped the former dairy around grass-fed meat, soil health, biodiversity, rotational grazing, and carefully managed genetics.
