Interluxe sets July 21 auctions for two Napa Valley properties

Interluxe Auctions will open separate online bidding July 21 for The Spring Mountain Estate and Juslyn Vineyards in Napa Valley. The two listings, both previously marketed at much higher prices, give buyers a choice to pursue a luxury residence, a vineyard business, or both.

Why it matters: - The auctions could reset pricing expectations in Napa Valley luxury real estate and wine country assets. - Buyers can bid on a private estate, a vineyard business, or both, with each property offered separately. - The sale adds a rare public auction process to two high-end Spring Mountain offerings.

What happened: - Interluxe Auctions announced separate online auctions for The Spring Mountain Estate and Juslyn Vineyards. - Bidding begins Tuesday, July 21, 2026, at 9:00 a.m. PDT. - The Spring Mountain Estate was previously listed for $13 million and now has a starting bid of $3.5 million. - Juslyn Vineyards was previously listed for $10 million and now has a starting bid of $3 million. - The auctions are being conducted online exclusively through Interluxe.

The details: - The Spring Mountain Estate spans 14.94± acres on Spring Mountain above Napa Valley. - The residence measures 9,600 square feet. - The home includes five bedrooms, five full bathrooms and one half bathroom. - The property includes expansive gathering spaces, a dedicated tasting room and a 5,000-bottle wine cellar. - Outdoor features include a 70-foot lap pool with integrated spa, an outdoor kitchen, koi ponds and terraced gardens. - The estate overlooks Napa Valley and the St. Helena Reservoir. - The interior includes a chef’s kitchen, a main-level primary suite and guest accommodations. - The estate sits minutes from downtown St. Helena. - Nearby access includes wineries, Michelin-recognized restaurants, luxury resorts and boutique shopping. - Juslyn Vineyards is located in the Spring Mountain AVA. - The vineyard spans 29.78± acres. - Juslyn Vineyards was established in 1997. - The vineyard has earned scores ranging from 90 to 97 points from The Wine Advocate. - Nearby wineries include Pride Mountain Vineyards, Barnett Vineyards, Lokoya and Smith-Madrone. - Interluxe said buyer’s agents are fully protected and a commission is being offered. - Previews are scheduled for Friday, July 17 from 11:00 a.m. to 3:00 p.m., Saturday, July 18 from 11:00 a.m. to 3:00 p.m. and Sunday, July 19 from 1:00 p.m. to 4:00 p.m. - More information, including due diligence and bid registration procedures, is available at the property information page. - Auction terms and conditions are available at Interluxe.

Between the lines: - Selling the properties separately widens the buyer pool by separating a residential trophy asset from an operating vineyard opportunity. - The steep drop from prior asking prices to auction starting bids suggests Interluxe is using price discovery to drive interest and urgency. - Spring Mountain’s privacy and proximity to St. Helena are positioned as a rare combination in the Napa market. - Juslyn is being marketed around its location inside a respected mountain AVA and its established winemaking track record.

What's next: - Bidding opens online July 21 and will determine whether one or both properties trade at auction. - Previews in the days before the sale will give buyers a final chance to inspect both assets. - Interluxe and The Agency will continue to market the properties ahead of the auction window.

The bottom line: - Interluxe is bringing two high-end Napa Valley assets to auction with sharply lower starting bids, betting that separate sales will create more competition and broader appeal.
