Chardonnay is the King of the white wine grape varietals – and features all over the world. The most expensive chardonnay exists in Burgundy with wines such as Meursault and Puligny Montrachet, as well as in California where there are some stunning options. It is strongly linked with Champagne – and is the 100% varietal in Blanc de Blanc champagne. You can now find Chardonnay in Spain, South Africa, Italy and Australia as a few examples.
