Introducing 375 Kortum Canyon—an architectural marvel and the crown jewel of Napa Valley entertaining. Perched high atop Diamond Mountain on 13± private acres, this reimagined coastal modern estate offers world-class luxury, seclusion, and jaw-dropping 360° views over Calistoga’s vineyards, Mount St. Helena, and the Palisades. Originally built in 1998 and completely redesigned for a full-scale interior remodel in 2025, no detail was overlooked in this four-story, 4,622± sq ft masterpiece. The result is an entertainer’s sanctuary that’s both dramatic and deeply livable.

Step inside to soaring ceilings, expansive picture windows, wide-plank white oak floors from Spain, and a custom floating staircase of wood, glass, and steel. The main level features a formal living room with dramatic fireplace, a temperature-controlled wine gallery, formal dining and a chef’s kitchen outfitted with custom European-inspired cabinetry, waterfall quartz island, Wolf/SubZero/Bosch appliances, and directly adjacent to the outdoor kitchen. The open family room also flows directly to outdoor spaces, as does nearly every room in the house.

Four bedrooms, four full baths and two half baths offer luxurious accommodations, including a showstopping primary suite with its own private balcony leading to the pool, spa-worthy bathroom, and an exquisite dressing room designed by California Closets. A new media room/bar lounge boasts an 85” screen, full wet bar, ice maker, and multiple view balconies—perfect for hosting viewing parties or late night card games. At the very top of the home, sits the “Eagle’s Nest” Suite—a private guest suite with spiral stair, and awe-inspiring 270° views. It’s the ultimate sanctuary for dreamers and stargazers.

​

Entertain outdoor effortlessly with a round pool and spa set against an iconic Wine Country backdrop, multi-level lounge and dining decks, and a full outdoor kitchen just steps from the chef’s dream interior. This is more than a home—it’s a private Napa Valley resort, only two miles from downtown Calistoga and 3 miles to the Four Seasons and Solage resorts. Simply put, 375 Kortum Canyon may offer the most extraordinary views—and lifestyle—in all of Wine Country.
