Locanda Margon
This is a big Italian list, 652 wines built around the house and its bubbles, with Ferrari alone running 113 listings and Tenute Lunelli another 22, so sparkling is the spine here, backed by 44 Champagnes if a guest wants to go French. The depth runs through Trentino Alto Adige and the two Piedmont and Tuscany red sections, with serious anchors like Tenuta San Leonardo, Antinori, Gaja, and Ornellaia, plus a real white bench in Alto Adige and imported Burgundy from names like Olivier Leflaive. Reds are the largest single category at 121 bottles, and there is genuine sweet and fortified depth too with 31 listings. Native bottle examples land around 65 to 160 EUR, so it is approachable for a one star but can climb with the trophy producers. The 21 wines by the glass give you room to work the floor, and the list rewards anyone who knows sparkling and northern Italian whites, while still covering classic Tuscan and Piedmont reds and Burgundy for the table that asks.
