There’s no business like family business. Just ask the Versaces, the Jacksons, or the Weinsteins.

Oh. And the Dentons.

See, when Jason Denton opened his button-cute West Village haunt ‘ino (and later Lupa), his younger brother Joe was right by his side. Now Joe’s taking the stage as full-on partner at ‘inoteca, an offshoot of the original ‘ino, which opens today.

Wine is still the name of the game at ‘inoteca, which has a selection of nearly 200 bottles and 25 wines by the glass or half carafe. Nibbles, courtesy of Chef and co-owner Kleinman, include the eminent truffled-egg toast, plus new items from paninis to piattis of melanzana lasagnette and frittata del giorno. Not to be missed: the salumi featuring culatello, a specialty of prosciutto crudo.

With a space three times the size of ‘ino, a downstairs wine cellar, private dining, and outdoor seating, ‘inoteca might just upstage its older brother.

Talk about sibling rivalry.

‘inoteca, 98 Rivington Street, at Ludlow Street (212-614-0473).
