Hoffmann Family Winery
Napa Valley Organic WinesRooted in Nature, Refined by Craft
Aum Cellars is a small, family-owned organic winery in Napa Valley, born from a simple idea: wine that respects the land, the grape, and the person drinking it. Frustrated by industrialization and heavy chemical use, our founder returned to older methods, with professional rigor. Organically farmed grapes, native yeast, and a light hand in the cellar keep each boutique bottling close to the vineyard it came from.
Meet the Winemaker
This isn't a tasting room. It's Pete's winery.
Pete Hoffmann has spent decades working among the vineyards of Napa Valley—as a vineyard manager, viticulture instructor, consultant, grape grower and winemaker. That experience shapes everything at Aum Cellars, from the way the vines are farmed to the way each wine is made.
But what makes a visit to Aum different isn't just Pete's experience. It's the opportunity to experience the winery with him.
There are no crowded tasting bars, scripted presentations or layers of hospitality staff between you and the person behind the wine. Pete often welcomes guests himself, walks them through the vineyard and cellar, pours the wines, and shares the decisions, experiments and stories behind what's in your glass.
Organic Wine Crafted With Soil And Soul
Pete Hoffmann, winemaker and viticulturist, believes great wine begins underground—where deep roots, living soil, and natural rhythms shape the character of every vintage. At Aum Cellars, the vineyard is farmed with organic practices and a light-touch philosophy that allows the land to play a defining role in the wine. Dry farming encourages vines to reach deep into the soil for water and nutrients, while sheep help naturally manage vegetation and return organic matter to the vineyard, supporting a balanced and resilient ecosystem.
In the cellar, that same philosophy continues. Native yeasts are allowed to guide fermentation, preserving the distinctive character of the fruit and the place where it was grown. Aum Cellars follows a Napoleonic winemaking approach, favoring restraint over manipulation and allowing terroir, vintage, and time to reveal themselves naturally. From dry farming and sheep-led soil balance to wild yeast fermentation, each decision is made with one goal: to create expressive wines that remain true to the vineyard from root to glass.
The Aum Experience
In Their Words
“Hidden gem in the Napa hills! The warm hospitality made us feel right at home, and Pete’s passion for winemaking made the experience unforgettable. His minimalist approach lets each wine truly shine, and every pour was exceptional. If you’re looking for an authentic, intimate Napa tasting away from the crowds, this is a must-visit!”

“A small group of us were recently hosted by Pete, the owner/winemaker, for a tasting of his amazing varietals. The intimate wine cellar is so unique that it, alone, is worth the trip. However, the incredible views, delicious wines (be sure to check out their creative monikers), and Pete's knowledge, humor, and personality make a visit an absolute must!”

“What an amazing experience in the valley today as it felt like we had traveled to Italy! Pete has such a passion for tending the vineyard, managing the olive trees, tending the sheep, and every step of the wine making process. Quite amazing...we certainly were blessed with this experience, enjoying a generous tasting, and sharing good times with friends. We will be back!”
