Sheree Thornsberry is the co-founder and CEO of Innumero Wines, a boutique winery rooted in the cool-climate appellations of Sonoma County, California. Alongside her husband Brian, Sheree turned a lifelong passion for wine into a visionary pursuit—leaving successful careers in St. Louis to build a winery that celebrates terroir, craftsmanship, and soulful expression.

Her journey into wine began with discovery and curiosity: a 2010 visit to Sonoma and Napa sparked an enduring appreciation for the depth and nuance of Northern California’s diverse vineyards. Over the next decade, extensive travels through Europe and South Africa expanded her palate and informed her understanding of what makes exceptional wine truly exceptional.

In 2018, a dinner-table conversation with her son planted the seed for a bold new chapter—prompting Sheree and Brian to pursue their dream of making wine. Together they founded Innumero Wines with a focus on crafting elegant, single-vineyard Pinot Noirs and Chardonnays that reflect the distinctive character of Russian River Valley and neighboring AVAs.

As the driving force behind the winery’s vision and operations, Sheree blends thoughtful leadership with an unwavering commitment to quality, community, and the artful balance between science and inspiration in winemaking. Under her guidance, Innumero has quickly gained recognition for its focused portfolio and authentic connection to place.
