Krupp Brothers Estate is a remarkable 20-acre Napa Valley winery property set among estate vineyards with sweeping views of Stags Leap, Atlas Peak, Lake Cynthia, and Mount St. Helena. European-inspired in design, the estate blends Old World character with New World elegance. Originally conceived in 2007 by Peter Kitchak and later acquired by Jan and Bart Krupp, founders of the iconic Stagecoach Vineyard and true Napa Valley royalty known for producing exceptional wines, the property has been thoughtfully refined into a fully turnkey offering. The estate includes a main residence, bonded winery, two tasting rooms, barrel room, and all necessary winery equipment. Current production is permitted for 15,000 gallons annually, with tastings and marketing events. A use permit modification is in progress to expand production capacity to 40,000 gallons, along with increased visitation and events. Approximately 9.73 acres are planted to classic Bordeaux varietals, 2.4 acres of which are currently leased. The 5679+/- sq ft Tuscan-inspired residence offers 4 bedrooms and 3.5 bathrooms, featuring hand-selected architectural elements imported from Italy. Highlights include a grand great room with vaulted ceilings and fireplace, a country-style kitchen, and a 3,000-bottle wine cellar with a cave-style portal opening toward the vineyard. Outdoor amenities include a covered veranda with an al fresco kitchen, built-in grill and fireplace, and an infinity-edge spa overlooking the vineyards and lake. A four-car garage with lifts allows for up to eight-car storage. A rare Napa Valley offering that seamlessly combines luxury living, vineyard lifestyle, and a fully operational winery.
