Premium Walnut Processing Facility Located in California’s Central Valley
DeRuosi Nut is a walnut processing facility located in the fertile San Joaquin County. Our facility processes a wide variety of both inshell and shelled walnuts including; Chandler, Howard, Hartley, Tulare and Livermore..
In 1947, after serving our country in WWII, Michael DeRuosi Sr. purchased an existing fruit dehydrator in Escalon, CA. Over the next several decades, the plant processed raisins, apricots, prunes, and walnuts. In 1980, at the age of 12, Michael DeRuosi III started helping his grandfather run the pruned plant.
In 1994, after graduating with a business degree and working for a few years in the banking industry, Michael DeRuosi III moved back home to partner with his grandfather and formed DeRuosi Nut. Since its inception, the company has expanded slowly and conservatively into a business that is now one of the premier walnut processors in the state of California.
