A Family Winery in Napa Valley
Our Story
Aum Cellars is the Napa Valley label of Hoffmann Family Winery — a small estate where Peter Hoffmann's lifelong love of the vineyard, patient craft, and a reverence for nature come together in every bottle.
Origins
The Story of Hoffmann Family Winery

For Peter Hoffmann, winemaking wasn't a career choice—it was part of his life long before he realized it would become his passion.
Growing up in Rancho Cucamonga, California, Peter was surrounded by agriculture. His family had deep roots in the land. His father cultivated avocados and citrus, his grandfather worked in the timber industry, and his great-grandfather raised horses. But perhaps the greatest influence came from his father, an avid wine enthusiast who made wine in the family garage.
My mentor and great friend Alan York was such an inspiration to my wine making and grape growing journey.

Peter was only eleven years old when he helped make his very first batch of wine. That same year, his father took him on a memorable trip to Napa Valley, where they visited the legendary Inglenook Winery. It was a moment that quietly planted a seed—one that would shape Peter's future in ways neither of them could have imagined.
Years later, Peter attended Cal Poly San Luis Obispo, earning a Bachelor of Science degree in Ecology and Systematic Biology before the university even offered a viticulture and enology program. Although his formal education focused on the natural sciences, his fascination with wine continued to grow. During college, he crafted his first independent vintage and discovered a lifelong appreciation for Rhône varieties, particularly Syrah.
One unexpected experience reinforced just how valuable exceptional wine could be.
Peter's father had carefully stored several cases of Inglenook wines purchased during that first Napa trip years earlier. Hoping to help with college expenses, he gave Peter four cases to sell. Peter stopped at a wine shop in Santa Barbara and offered a case for $700. Instead, the owner purchased just three bottles of 1975 Inglenook Cabernet Sauvignon—and handed Peter a check for $2,100.

It was an eye-opening lesson in the craftsmanship, rarity, and enduring value of great wine.
After college, Peter immersed himself in vineyard management throughout California's Central Coast, working with premium vineyards and developing expertise in sustainable grape growing. His reputation eventually brought him to Napa Valley in 1997, where he managed renowned vineyard holdings before joining Stag's Leap Cellars as Vineyard Manager in 1999. Over the years, he also taught viticulture at Napa Valley College, served as a Grower Relations Representative for Treasury Wine Estates, and provided vineyard consulting throughout Napa Valley.
Despite his extensive experience growing grapes for some of California's finest wineries, Peter waited patiently before launching his own label.
In 2000, he began making small lots of wine for himself. Three years later, he released his first commercial vintage, marking the beginning of what would become Aum Cellars and, ultimately, Hoffmann Family Winery.
Today, Peter's philosophy remains refreshingly simple: let the vineyard speak.

His wines are organically farmed, crafted with native yeasts, unfined and unfiltered, and produced with minimal intervention. Rather than relying on heavy oak or overripe fruit, Peter believes great wine should express the unique character of its vineyard and grape variety.
He often compares excessive oak to covering natural beauty with too much makeup. A truly exceptional wine, he believes, should never hide its identity—it should reveal it.
That philosophy guides every bottle produced under the Hoffmann Family Winery label: wines with balance, elegance, authenticity, and a genuine sense of place.
For Peter, winemaking isn't about following trends. It's about honoring the land, respecting the vineyard, and crafting wines that tell the story of where they come from—and the family that has dedicated generations to caring for it.
Peter Hoffmann — Why I started making wine
Our Philosophy
We adhere to strict principles to ensure the purity of our wines. Nothing is added, and nothing is taken away, save for minimal effective sulfur at bottling when absolutely necessary.

Wild Fermentation
We rely entirely on native yeasts naturally present on the grape skins and in our cellar. This unpredictable process yields complex, layered flavors unique to our estate.
Minimal Intervention
No fining, no filtration, no color enhancements or flavor additives. Our wines are unfiltered and raw, preserving their natural texture and vitality.
Handcrafted Small Batches
Every decision, from pruning to harvest, is made by hand. Our production is intentionally small, allowing us to maintain absolute focus on quality over quantity.

Frequently Asked Questions
Aum Cellars is the Napa Valley label of Hoffmann Family Winery, founded by Peter Hoffmann — winemaker and viticulturist. The estate is a small family winery, not a high-volume tasting room.
Most Aum Cellars wines are estate grown in Napa — Coombsville, Atlas Peak, and beyond. A few reserve bottlings, including Russian River Pinot Noir and Sierra Foothills Grenache, are made from sourced fruit and are labeled that way.
The vineyard is organically farmed and dry-farmed, with a light hand in the cellar: native yeast, unfined and unfiltered wines, and no recipe winemaking. The aim is wine that tastes of the place it grew.
No. Aum Cellars farms organically — without synthetic pesticides, herbicides, or chemical fertilizers — but we are not a certified-organic winery. We do not use USDA or CCOF certification language for the estate.
Unfiltered Authenticity
We invite you to taste the difference that dedication to craft makes. Our wines are not meant to be perfect; they are meant to be alive. They evolve in the glass and tell the story of the season that created them. Walk the vineyard with us, or request a private tasting at the estate.
