Farm to Fermentation

Stepping Stone Farm is our one acre no-till biodynamic farm in Napa, CA where we grow all of our produce used in Rice Flower products. Our farming approach honors the life in the soil above all else

Stepping Stone Farm- A one ancre biodynamic no till farm in Napa, CA

Haruna (wife) is the master fermenter, Patrick (husband) is the farmer, and together they steward the invisible world of microbes found both outside and inside of us.

They are grateful to share this cycle of health- from soul to gut, from farm to jar.

Sustainable Practices

Rice Flower products are packaged in glass jars with minimal packaging and limited plastics. Outside of our farm grown produce, all of our ingredients are organic, locally sourced, and are chosen based on the relationships we cultivate with the purveyors who honor their craft and products as much as we do.

Thanks to you, we continue crediting our customers who return their jars to be reused in our production. Closing the waste gap one jar of goodness at a time.
