Robert Steinhauer

Robert "Bob" Steinhauer, an iconic figure in California viticulture whose five-decade career reshaped modern winegrowing and elevated the profession of vineyard management, died on November 28, 2025. He was 84.

Born in 1941 to Edward and Freda Steinhauer in Exeter, California, Bob grew up in Easton, where his family farmed raisins. His earliest and most cherished memories were of riding on the fender of his Uncle Roy's tractor from age 12 and working beside his cousin Leonard Hoskins in the raisin vineyards - experiences that rooted in him a lifelong love of farming, vines, and the people who tend them. Early on he was known for the traits that would define him for life: a sharp wit, a love of storytelling, and an energetic presence that seemed to stir the air around him. Friends would later call him a "force of nature," and said that when he walked into a room, or a vineyard, the energy level instantly rose.

Bob earned his B.S. in Viticulture (1965) and M.S. in Plant Science (1969) from California State University, Fresno. He was among the first students to complete the newly created viticulture degree, developed by Professor Vince Petrucci, making him one of Fresno State's first college-trained viticulturists. This foundation laid the groundwork for a career that would influence the course of premium winegrowing throughout the state, and later, Bob was instrumental in raising funds for the establishment of Fresno State's Vincent E. Petrucci Library.

Bob began his career in the late 1960s, managing 5,000 acres of vineyards for Schenley Industries in California's Central Valley, where one of his responsibilities was negotiating some of the state's first farmworker union contracts. In 1971 he moved to Napa Valley to work for Andy Beckstoffer at Napa Valley Vineyard Company. Hired as a "college-trained viticulturist" to modernize vineyard practices and elevate fruit quality, Bob farmed historic properties for Inglenook and Beaulieu Vineyard and forged a formative relationship with winemaking legend André Tchelistcheff, who became both mentor and inspiration.

In 1979, Bob joined Beringer Vineyards (later Beringer Blass Wine Estates and Treasury Wine Estates), where he would spend 26 years, ultimately serving as Senior Vice President of Vineyard Operations. During his tenure, Beringer's farming footprint expanded dramatically, from a couple thousand acres to more than 10,000 across multiple California appellations. He managed the company's estate vineyards and collaborated with more than 300 winegrape growers statewide.

Bob played a pivotal role in the development of Beringer's critically acclaimed Private Reserve Cabernet Sauvignon and Chardonnay programs and its Single Vineyard Napa Valley wines. He was equally central to the company's expansion into the Central Coast, helping diversify its grape supply and laying the foundation for new AVA-driven brands and bottlings. Jim Efird of Pacific Vineyard Company said, "I cannot provide an accurate accounting of the thousands upon thousands of acres of vineyards professionally established in San Luis Obispo and Santa Barbara Counties under Bob's direct guiding hand."

In recognition of his extraordinary impact, Beringer named one of its Howell Mountain estate vineyards Steinhauer Ranch, an honor seldom bestowed in the wine industry. In the early 2000s the company also named its Santa Barbara County winery "Taz" after him, a reference to his nickname "Tasmanian Devil," given for his habit of rushing into vineyards or offices, delivering rapid-fire questions or instructions, and rushing off just as quickly. In Beringer's White Hills Vineyard in Santa Barbara County, a park was named Steinhauer Park in his honor. Industry colleagues widely credit Bob with building one of Napa Valley's most advanced, research-driven, and technically sophisticated vineyard programs in his time at Beringer.

After retiring from Beringer in 2005, Bob founded Wineland Consulting LLC, where he advised a select group of high-quality wineries and vineyards for the next 20 years. He continued to influence the industry by advocating for modern, data-informed vineyard practices and mentoring the next generation of winegrowers.

Bob's leadership reached far beyond the vineyards he managed. He was a Fellow in the newly formed Agriculture Leadership Associates beginning in 1971. He served as President of the American Society for Enology and Viticulture (1985–1986), the first viticulturist ever chosen for the role, breaking precedent and inspiring a generation of vineyard managers. He served as Chairman of the California Grower Foundation (1982–1983), President and Board Chair of Napa Valley Vintners (2004), Chairman of the statewide Pierce's Disease and Glassy-winged Sharpshooter Board (successfully helping pass the PD/GWSS Grape Growers Assessment) and more recently was a member of the International Technical Working Group for the European Grape Vine Moth. He also served as a Director of the American Vineyard Foundation (1988–2001) and chaired the Program Development Committee for the Unified Wine & Grape Symposium (2006–2008).

His work earned him numerous accolades, including the Napa County Farm Bureau Agriculturist of the Year Award (2010) (for which he received U.S. Congressional recognition); ASEV Merit Award (2008); Fresno State's "Top Dog" Outstanding Alumnus Award (2006); Lodi Winegrape Commission Wine Integrity Award (2005); Copia Winegrower of the Year (2004); Fresno State Viticulture & Enology Research Center Bloom Award (1994); and Foremost-McKesson California Vintners Award (1983).

But Bob's most enduring legacy may be the way he elevated the direction and profession of viticulture itself. From the mid-1980s through the 2000s, a period of massive wine industry growth and change, he was one of the most influential voices in viticulture - intellectually rigorous, deeply curious, and unafraid to challenge established thinking. He attracted support for viticultural research, set the agenda for what needed to be studied, and pushed researchers to be better. He was known for asking the toughest questions, yet once convinced, he would be the first to implement research findings in the field and often improve upon them.

Colleagues described him as a "font of knowledge," a man who knew every inch of Napa Valley and could tell you anything about a vineyard's past, present, or potential. Nick Dokoozlian, Vice President of Viticulture, Chemistry, and Enology at E&J Gallo, commented, "Before Bob we were all farmers. Bob became the first winegrower." Richard Mendelson of DP&F Law observed, "He was the leading viticulturist of our era."

Bob cared deeply about the welfare of vineyard workers, advocating for fair pay, health insurance, and pension benefits for those who worked in the vineyards. His respect for vineyard laborers was unwavering, and he considered them essential partners in crafting fine wines.

Bob was a natural storyteller -one who could make short stories long, savor a good glass of red wine, barbecue with gusto, or linger over a family meal in the shade of the camphor tree. Among his favorites was a tale from South Africa, where he learned that a peculiar vineyard fence was designed to keep out baboons. "Is that the worst problem you have?" he asked, only to be told, "No, the worst is when the winemakers come in!" It became a running joke for years.

Even near the end of his life, Bob spoke and dreamed of farming, vineyards, and work. He loved his family, his friends, the land, and the profession that defined him. He often said, simply and proudly, "I had a great life."

Bob is survived by his wife - the rock of his life for 57 years - Verna Grimm Steinhauer; his children, Erik John Steinhauer (Audrey); Anne Christine Steinhauer; his beloved granddaughter, Parker Gayle Steinhauer; and his cousin, Leonard Hoskins.

In lieu of flowers, donations may be made to the American Vineyard Foundation, Justin Meyer Graduate Student Research Fellowship (avf.org), in honor of Bob's lifelong dedication to advancing viticulture.

A celebration of life will be planned for Spring 2026.
