Mraz & Sohn
This is a deep, serious list of over 1,500 wines built squarely around Burgundy, which dominates with more than 300 listings and shows up in the Meursault and Puligny Montrachet bottlings you will field questions about. White wine is the backbone here, nearly 500 references against 354 reds, and the supporting cast leans toward classic and somm friendly regions like the Loire, Bordeaux, Piemont, plus a real bench in Jura and local Austrian strength out of Burgenland. Champagne is well covered with roughly 70 sparklers, and there is a notable run of large formats under Grossflaschen for the big tables. Be ready to guide on price, because the bottles run high with examples around 325 to 500 EUR and there is no by the glass program, so every pour is a full bottle commitment. This rewards a guest who knows what they want and wants to drink Burgundy at depth, not someone browsing casually.
