Krug Grande Cuvée is an excellent champagne, and several airlines serve it in international first class. It’s a blend of wines from 10 or more vintages and from a combination of pinot noir, chardonnay and pinot meunier. And it’s cellared for at least six years. You’ll often pay $160 or more in a bottle shop.
However Singapore Airlines is introducing Krug 2004 “on all First Class and Suites flights where both” Dom Perignon and Krug are normally served.
