at Trinchero Family Estates

The fourth largest winery in the United States, Trinchero Family Estates has remained a family-owned Napa Valley-based company since 1948. Now, with over 1,000 employees, over 10,000 acres of vineyards, more than 50 wine and spirits brands and millions of customers, Trinchero Family Estates continues to stand by its commitment to the land and the people behind the growth of its business.

Since Mario Trinchero brought his young family to Napa Valley and purchased an abandoned Prohibition-era winery called Sutter Home in St. Helena, Trinchero Family Estates has embraced its responsibility to the environment and community. To this day, every employee remains committed to upholding the winery’s values and spirit of giving that Mary and Mario established in 1948, growing Trinchero Family Estates’ dedication to the environment, charitable giving and responsibility with sustainable farming practices and innovative philanthropic initiatives.

Trinchero Family Estates strives to be an industry leader in sustainable farming, waste reduction/ recycling, water conservation and energy efficiency with environmentally friendly efforts across all aspects of the business. As one of the Trinchero Family Estates company values, every employee in each facility, office, winery and vineyard is committed to sustainability.

Water Conservation

  • Trinchero Family Estates’ Green Island Road Production Facility and Westside and Main Street Wineries are participants in Certified Sustainable Wine Programs.
  • Advanced wastewater treatment systems at these facilities process thousands of gallons of water per day. Treated water in the irrigation ponds exceeds required standards and is reused to provide water for landscaping, wildlife and crops.
  • 70 percent of all processed water is reused for landscaping or crop irrigation, ensuring the water returns back to the earth.
  • In contrast to the industry average of five to six gallons of water used to make one gallon of wine, Trinchero Family Estates used 3.5 production gallons in 2017. This reduction in water usage saves millions of gallons of water annually.

Commitment to the Earth

  • All of Trinchero Family Estates’ owned vineyards are sustainably farmed.
  • Trinchero Family Estates is dedicated to minimizing the use of chemicals for pest and weed control in all company vineyards.
  • Owl boxes give owls a place to live and control rodents and other pests that cause damage to grapevines, without the use of chemicals or traps.
  • Thousands of tons of grape skins, seeds and stems are converted into compost for vineyards, nutriceutical use and cattle feed.

Energy & Greenhouse Gas Reduction

  • Trinchero Family Estates transitioned its energy use at all of its 28 facilities and vineyards in the Napa Valley to Deep Green 100 percent renewable energy.
  • The flagship Westside Winery facility in Lodi was designed with environmental considerations in mind. The facility is estimated to reduce truck trips by 2,400 trucks per year, totaling annual reduction of over 120,000 truck miles, saving on fuel and reducing related emissions.
  • In the vineyards, most of the grapes are picked at night when temperatures are cooler, reducing the need for winery refrigeration.
  • Trinchero Family Estates has invested in energy-efficient refrigeration systems, lighting and insulated tanks to promote efficient energy usage.
  • Solar panels provide power for the facilities, helping to conserve energy. The photovoltaic (PV) solar systems in Lodi and at the Clements, CA vineyard alone generate approximately 750 kilowatts of electricity, and since installation have generated the equivalent of avoiding 6,330 metric tons of CO2, or 6.9 million pounds of coal burned, or 15 million car miles driven.
  • Trinchero Family Estates utilizes refrigeration systems that use ammonia instead of high-GHG potential chemicals.
  • Trinchero Family Estates employs alternative energy generation stations to reduce the winery’s demand from the grid.

Zero Waste

  • Waste reduction is a part of the company-wide DNA. Over 2,000 tons of materials–including glass, plastic and paper– are recycled each year.
  • Trinchero Family Estates has incorporated a zero waste goal for operations, achieving 99 percent diversion in 2017.
  • Wine bottles used are made of up to 50 percent recycled glass, and utilize lighter-weight glass where possible to reduce waste and carbon footprint.
  • Trinchero Family Estates takes pride in working with suppliers to minimize packaging.
  • Pallets, drums, shipping boxes and packaging are shipped back to vendors for reuse.
  • Glass, corks, capsules and containers are recycled.
  • Trinchero Family Estates was the only Northern California winery honored with a WRAP (Waste Reduction Awards Program) Award from California’s Integrated Waste Management Board every year from 2000 to 2011. In addition, the company received the WRAP of the Year Award in 2005.
  • In 2017, Trinchero Family Estates was honored with the Stockton Chamber of Commerce P3 Stewardship Award.

Alternative Packaging

  • Trinchero Family Estates continues to research more environmentally friendly packaging alternatives for products, from bottles, boxes and labels to corks, closures and cartons. The company strives to reduce the weight and amount of materials needed to deliver its products.
  • Sutter Home PET bottles are 100 percent recyclable and lightweight. Shipping PET uses about half the energy used to ship glass. Production of PET bottles generates roughly less than 60 percent of the greenhouse gases used to produce glass bottles.
  • Bandit wines and a selection of Sutter Home wines are boxed in environmentally friendly Tetra Pak® packaging made primarily from paper, a renewable resource. Tetra Pak uses 92 percent less packaging, 54 percent less energy, creates 80 percent fewer greenhouse gases and requires 35-40 percent fewer trucks to deliver the same amount of wine, as compared to glass bottles.
  • Trinity Oaks uses plant-based capsules made from EarthFirst® PLA Film, produced using renewable technology. The PLA capsules are a more sustainable alternative to petrochemical-based films. They use less energy and are made in a greenhouse-neutral facility utilizing solar, wind and other energy offsets. The PLA material used in the capsule is certified compostable, and the aluminum top disk on the bottle is recyclable.
  • Trinchero Family Estates is a pioneer in lightweight glass, requiring less energy to make, less freight to transport, and less cost to produce wine. Savings have been estimated at roughly 20,000 barrels of oil equivalent by greenhouse gas calculations.
