California’s Napa Valley is prized for its vineyard views and quiet country roads, which create a relaxed atmosphere that blends rural simplicity with polished sophistication.

Tucked away in St. Helena, a 40-acre spread that epitomizes the NorCal wine region’s casual elegance has come available with an 8,500-square-foot main residence overlooking Lake Hennessey, in addition to two detached guesthouses. Among its many refreshing outdoor luxuries are a 60-foot lap pool and a full-size tennis court amid bucolic grounds. Ginger Martin of Sotheby’s International Realty, St. Helena Brokerage, holds the $18.5 million listing, which sits mere minutes from the revered Silverado Trail.

Sunlight filters through an abundance of greenery to illuminate the Tudor-style main home’s entrance courtyard, where a water fountain greets owners and guests. The main living area comprises ample lounge and dining areas beneath a vaulted, exposed beam ceiling, while the chef’s kitchen, with a central island, built-in breakfast seating area, and wood-finished cabinetry, sprawls out nearby. Nearby are a spacious catering kitchen and a wine cellar.

A dozen people can alternatively dine in the sunroom or step out onto the rear of the home via a trio of glass doors framed in custom ironwork. A stately pergola laced with foliage shades one of several alfresco dining areas just a short stroll from the infinity pool with panoramic vistas of the serene lake and mountains ahead. One of the estate’s seven fireplaces keeps outdoor diners warm when the temperatures dip.

Back inside, walnut hardwood floors lead to the carpeted primary bedroom that opens to a private patio. The suite’s rustic walk-in closet space, as well as its stone-finished ensuite are other highlights. Three more bedrooms are spread across the newly remodeled two-story abode alongside another three baths and two powder rooms. A family room and two offices round out the main abode’s key amenities.

Venetian plaster walls and French limestone floors, meanwhile, elevate the airy designs of both 1,000-square-foot guesthouses. Each has a great room with soaring ceilings, a wood-burning fireplace, and easy access to the idyllic grounds where you can partake in friendly matches on the tennis and bocce courts or hit the Silverado Trail that’s ideal for walking and cycling.

The property, which includes one acre of cabernet vines, sits on Pritchard Hill, “the number one wine-growing AVA (American Viticultural Area) in the Napa Valley,” Martin tells Robb Report. For those who would like an even larger spread, a 60-acre neighboring parcel is also available separately.
