This is a 139 bottle list built around grower Champagne and serious white wine, with Austria, the Mosel, and Spain leading the whites and a red side anchored in Piedmont, Tuscany, Spain, and California. The producers tell the story: Egly Ouriet and Jacques Selosse for fizz, Didier Dagueneau and Keller for cerebral whites, Sadie Family and Remelluri on the Iberian side, plus serious Burgundy that climbs all the way to Romanee Conti La Tache at $5,790. It rewards a guest who knows growers and offbeat regions more than one chasing big labels, and there is real range, from $22 up into the thousands with a median near $220, so you can sell honestly at most price points. The catch is the glass program, only four wines, so most of the work happens by the bottle and you need to be ready to guide people there. Lean on the white depth and the grower Champagnes, since that is where this list is strongest and deepest.
