Former San Francisco Giants owner Peter Magowan and his wife, Deborah, built a Napa Valley retreat that doubled as a working vineyard — and a place where the couple leaned into the region’s signature lifestyle: wine, views and gathering friends around a table.
Now their St. Helena estate at 150 Mills Lane has come to market for $13 million, offering a 20-acre compound that blends resort amenities with agricultural bones.
The listing describes a property “designed for both relaxed living and large-scale entertaining,” with seven bedrooms, six full bathrooms and 7,175 square feet of interior space on 19.86 acres.
The grounds are arranged for the kind of indoor-outdoor flow buyers expect in upper-end wine country — an emphasis underscored by a resort-style pool and spa, an expansive outdoor kitchen pavilion and a dedicated catering kitchen meant to support events without turning the main house upside down.
The estate’s polished, turnkey feel is matched by the infrastructure that makes a property of this scale easier to run. The site includes solar power, multiple wells, advanced irrigation systems and a Control4 smart home platform, according to marketing materials — practical details that matter for second-home owners or anyone trying to manage a large property with minimal friction.
But the calling card is the vineyard.
The listing says the estate includes approximately 15 acres of planted vines, with varietals including Sauvignon Blanc, Cabernet and Petite Verdot, creating both a scenic backdrop and a potential source of income. For a buyer weighing Napa real estate as both lifestyle and legacy purchase, the combination can be compelling: a home that looks like a vacation and functions like a small business.
The Magowans took that dual identity seriously. They maintained the vineyards and harvested grapes that were sold to wineries — and that they embraced the home as an entertaining hub, according to the Wall Street Journal. Debbie Magowan told the Journal the couple frequently hosted holidays and birthday parties there, a detail that fits the property’s party-ready design.
Magowan died in 2019 at age 76.
