About the Products

Offering both shelled and inshell almonds and all major varieties of whole almonds in a wide range of sizes, and almonds chopped, sliced, slivered, in flakes and meal. Seasoned whole almonds are also available in nine flavors. These are all natural with no artificial ingredients.

Major varieties of walnuts are offered in a wide range of sizes and color grades and combinations including halves, and large, medium and small pieces, as meal, and in large, medium and small nuggets. Clients seeking Mariani nuts include consumers as well as foodservice and industrial companies such as confectionary, cereal and ice cream makers, to name a few.


In 1972, cousins Jack and Dennis Mariani scouted new farming opportunities outside of the booming Santa Clara Valley and identified the Winters microclimate as an optimum site for their walnut orchard and processor. Jack’s brother Martin joined later in the same decade and helped the family venture into the almond industry. Mariani nuts are distributed throughout North America, Europe, Asia and Australia.

In 2008, the company was named one of the New California 100 recognizing business success and entrepreneurial innovation in the Great Central Valley by co-sponsors UC Davis and Golden Capital Network.


A full line of consumer packaging options consistent with the retail environment are offered. Industrial clients may specify corrugated cartons with poly-lined bags, fiber bins or vacuum pack.


Company operations are located in Winters in California’s fertile northern central valley.

Product Quality

Varieties are selected and matched with optimum growing conditions to deliver a premium product. Care is taken by long-term, experienced employees who control quality from harvest to the package. Numerous grading takes place throughout the processing and random samples are tested for product safety and sanitation. All walnuts meet or exceed the standards set by the Walnut Marketing Board and are enforced by a third-party, the American Council for Food Safety & Quality (DFA of California). Mariani also participates in the voluntary almond sampling for Aflatoxins and orchard sanitation programs.
