Mariani Nut Co. was founded in 1972 by two cousins – Jack & Dennis Mariani – who came from the Santa Clara valley. Looking for new farming opportunities outside the burgeoning Santa Clara valley, they found a very similar micro-climate 60 miles northeast of San Francisco in the town of Winters. Initially the company started off as a very small processor that mainly handled the walnuts from our own orchards.

Later, in the 1970’s, Jack’s brother – Martin – came and joined the company. The company then ventured into the almond industry and further expanded the operation.

Over the course of three decades Mariani Nut has grown steadily, due in large part to the quality conscious growers whose product we process. In addition, a highly dedicated and skilled employee base has allowed us to continuously improve our manufacturing processes and quality controls. This, in the end, has allowed us to consistently meet our customer’s specifications & expectations for over 35 years.

Today Mariani Nut Co. has grown to be one of the largest, privately-held, walnut and almond processors in the world. To the same extent, the farming operation has also grown to several thousand acres.

Mariani Nut Co. still supplies walnuts & almonds from our own orchards today, as we did back in 1972, but we also have a very large number of growers who are positioned statewide, that supply nuts to us.

Over the years, Mariani Nut Company has developed many strong partnerships with customers that demand the highest quality obtainable and insist on continuous improvement. These partnerships, with companies in a variety of sectors including confectionary manufacturing, cereal, etc., have pressed us to implement an aggressive investment strategy when it comes to manufacturing capital. This strategy has allowed us to obtain a position of leadership regarding Quality in the industry.

Mariani walnuts & almonds reach virtually all regions of the world. Our products find a home not only here in the U.S., but a significant tonnage is also shipped to Europe, Asia & Australia. Please visit the "Products & Markets"section of the site to find more specific product information.
