From a small family farm to a global nut processor, Mariani Nut Company blends tradition, innovation, and sustainability to meet evolving market demands
Nestled in the small town of Winters, California, Mariani Nut Company has grown from a modest family operation into one of the largest privately held nut processors in the world.
Founded in 1972 by cousins Jack and Dennis Mariani, the company initially focused on walnuts before expanding into almonds when Jack’s brother Martin joined the business.
What began as a small processing facility serving the Mariani family’s orchards has since evolved into a vertically integrated operation, sourcing nuts from a vast network of growers and supplying products to major retailers, food manufacturers, and international markets.
Despite its impressive growth, Mariani Nut Company has remained deeply rooted in its agricultural heritage.
The family’s farming history dates back to the Santa Clara Valley, once a flourishing region for orchards before the rise of Silicon Valley pushed agriculture out.
Anticipating these changes, the Marianis relocated their farming and processing operations to Northern California, where the climate and soil proved ideal for nut cultivation.
Over the decades, the company has built strong partnerships with local growers, fostering trust through fair business practices and long-term collaboration.
A key factor in Mariani Nut Company’s success has been its ability to adapt and diversify.
Beyond farming and processing, the company has expanded into private-label packaging and bulk supply for industries like confectionery, cereals, and ice cream.
See’s Candies, a well-known California chocolatier, has been a longtime customer, using Mariani nuts in its signature treats.
This multi-tiered approach allows the company to remain resilient in the face of market fluctuations, ensuring a stable business model that benefits both growers and consumers.
Sustainability has also played a significant role in Mariani Nut Company’s development.
The company has committed to environmentally responsible practices, investing in renewable energy and waste reduction initiatives.
In 2024, Mariani Nut installed solar panels capable of generating 100% of the power needed for its processing facilities.
By 2025, the company aims to complete its transition to an all-electric forklift fleet, further minimizing its environmental footprint.
Additionally, Mariani Nut operates as a zero-waste facility, repurposing by-products such as nutshells and hulls for livestock feed, bedding, and soil aeration.
These efforts demonstrate a long-term vision for sustainable agriculture that prioritizes both productivity and environmental stewardship.
Another aspect that distinguishes Mariani Nut Company is its strong focus on consumer engagement and market expansion.
Traditionally, nuts were stocked in the baking aisle of grocery stores, reinforcing the idea that they were primarily ingredients for cakes, cookies, and breads.
The Marianis recognized the untapped potential in promoting nuts as standalone snacks and versatile cooking staples.
They worked closely with retailers to reposition nuts within stores, highlighting their role in healthy eating trends.
Today, their website showcases a variety of recipes that emphasize the versatility of almonds and walnuts, from protein-rich breakfasts to savory salads.
The company prides itself on delivering premium nuts that are carefully selected and minimally processed to preserve their natural flavor and nutritional value.
Whether it’s organic, natural, or Marcona almonds, the company ensures that each product meets high standards.
This dedication has earned Mariani Nut a reputation for reliability among retailers and food manufacturers worldwide, with their nuts being distributed not only across the United States but also in Europe, Asia, and Australia.
Beyond business, Mariani Nut Company places a strong emphasis on supporting its employees and local community.
As one of the largest employers in Winters, the company fosters a workplace culture that values employee growth and well-being.
Many workers have remained with the company for decades, a testament to the strong relationships and fair treatment that have defined the business since its inception.
Through a combination of strategic diversification, sustainable practices, and strong partnerships, Mariani Nut Company has positioned itself as a leader in the nut industry.
