A brief history

Our meticulously designed St. Helena winery is an enduring symbol of everything our family has worked toward for over 70 years. It represents three generations committed to crafting wine of the utmost quality. It is a beacon, heralding both our roots and our future in the Napa Valley. With stunning views of Spring Mountain to the west and Howell Mountain to the east, our winery sits at the heart of Napa Valley, not far from where Mario Trinchero lived when he arrived in California over 70 years ago. The 22-acre site houses our winery, tasting room and hospitality center—all overlooking the Cabernet Sauvignon vines on Mario’s Vineyard. The winery is a work of art unto itself—the perfect place to craft our estate-grown, limited production wines. Every detail of its design was conceived to create wines of exceptional caliber, from the sophisticated cold grape storage and sorting equipment, to the small fermentation tanks used for isolating especially promising lots. Our wines reflect our most pristine, estate-grown grapes, thoughtfully tended in the vineyard and ultimately hand-picked and scrupulously hand-sorted in the cellar. Following fermentation, we stay close to our wines as they age. Our barrel room is home to oak barrels from some of the most respected coopers in France. Hundreds of small steps are taken every day to ensure we create truly unique wines, handcrafted with care and integrity. We focus on small-lot winemaking, with unwavering attention to detail, to yield luxury wines that embody quality and dedication to the craft.

Meet The Team

  • Landon Donley

    Trinchero Napa Valley winemaker Landon Donley brings deep wine knowledge and a wide breadth of industry experience to his role at the family-owned winery. With a career spanning fine winemaking at esteemed Spottswoode Estate Winery and Buccella in Napa Valley, to fine wine sales at distributor Southern Wine & Spirits in Santa Monica, Landon developed his interest in and passion for the industry first-hand.

    Landon got his first taste for wine while growing up in Northern California’s foothills. After earning his bachelor’s degree in business management from California State University–Long Beach, Landon set out to deepen his wine knowledge with first and second level Court of Master Sommelier certifications along with a certified specialist of wine accreditation from the Society of Wine Educators. Equipped with those credentials, Landon set out to explore international winegrowing regions and gain a greater understanding of both Old and New World winemaking styles.

    Upon returning home, Landon was drawn to the art of winemaking and earned a second bachelor’s degree in enology from California State University–Fresno. After graduation, his love for wine and travel inspired him to join the Molly Dooker winery team in Australia. Landon then returned to his home state of California, where he began working with Spottswoode Estate as a harvest intern in 2010. Spottswoode promptly recognized his talent and promoted him to assistant winemaker in March 2011. In 2015, Landon joined the Buccella team as winemaker where he crafted the bold, layered wines for which the winery is known.

    Landon joined the Trinchero Napa Valley team in 2020 and brought with him tremendous talent and a fresh take on the label’s valley floor and mountain fruit sourced from their coveted estate Napa Valley vineyards. He currently resides on Howell Mountain with his wife—a fellow winemaker—and his family.
