This 2012 vintage of Pol Roger uses 100% Chardonnay grapes, all hand selected from the Grand crus of the Cote des Blancs, these are then united together and aged for 6 years in their cellars. This particular expression goes through two stages of fermentation-during the second stage, each bottle is hand-turned (or using the technical term "riddled") everyday to encourage the breakdown of the yeast; which creates a rich flavour profile hidden inside this sensational bottle of Champagne.
