You just dropped tens of millions on a hot slice of Manhattan real estate. But that doesn’t mean you’re in the club.

In October, the city’s poshest new private supper club will open in 35 Hudson Yards — the mixed-use mega development’s crown jewel, where billionaire developer Stephen Ross is occupying the penthouse.

But buying one of the tower’s 143 luxury apartments — ranging in price from $5.1 million to $27.7 million — or booking a night at its Equinox branded hotel doesn’t mean you’ll be sipping burgundy by the fire in the exclusive bar and lounge.

“It’s not for residents,” a source familiar with the project told the Post. “It’s for the developer’s super-rich buddies and CEO friends. Residents can join but it’s so expensive.”

Dubbed WS New York, the club is a collaboration between Related dining guru Kenneth Himmel and Wine Spectator publisher Marvin Shanken.

A rotating cast of Michelin-starred chefs and sommeliers will create regular special events for members.

The wine list will be curated only from vintages rated 90 points and above by the magazine, in its first such venture. Two master sommeliers, both of whom passed the legendarily grueling qualifying exam on their first try, will direct the second-floor space along with St. Regis general manager Paul Nash.

Architect David Rockefeller designed the modern meets old-school interiors around a central hearth and selected low-backed club furniture for the den-like dining room.

Related declined to comment on how much membership will cost, or anything else to do with the hush-hush project.

Those who live in the 92-story building won’t be given any special membership privileges, sources tell the Post — although there will be an elevator that connects the club directly to the residences and a public-facing, ground-level tavern attached for millionaire plebs who want to drown their sorrows over what they’re missing upstairs.

Ross isn’t the only developer touting a new exclusive club. In fact, after seeing declines for decades, private clubs have once again become the ultimate real estate trick.

Extell’s Gary Barnett plans to open a new Central Park Club in his Central Park Tower, soon to be the world’s tallest residential building. It will boast three floors, 50,000 square feet, “curated luxury amenities” and a “unique experience complemented by five-star service.”

Extell did not return the Post’s requests for comment.
