Borgo Sant'Anna
This is a serious, Piedmont anchored list of over 1,500 bottles built squarely around Nebbiolo, which accounts for roughly 740 of them, so expect deep verticals and broad coverage of Barolo and Barbaroo growers right in the restaurant's backyard. The strength is the local roster of top names like Giacomo Conterno, Paolo Scavino, Ceretto, and Pio Cesare, backed by plenty of Barbera d'Alba and a respectable white selection led by Chardonnay and Arneis. Reds dominate at 842 listings, with a smaller but real sparkling section of 119 and a modest dessert and fortified group. Pricing skews toward the collector end, with examples landing around 110 to 270 EUR, so this is a list for guests who know Piedmont and want to drink it at depth. One thing to flag for the floor: there is no by the glass program, so every pour here comes from a full bottle.
