Maison Pol Roger owns 92 hectares of vineyards on prime sites in the Vallée d'Epernay and on the Côte des Blancs. Its cellars run for 7km and are on three levels, the deepest known as the ‘cave de prise de mousse' at 34m below street level. As the name suggests this is where the wine undergoes its secondary fermentation in bottle. The fact that this deep cellar is at 9°C or less, rather than a normal cellar temperature of 11-12°C, prolongs this fermentation and contributes to the quality and particular style of the wines and their famously fine bubbles. Indeed, it is this quality which brought about Sir Winston Churchill’s lifelong attachment to Pol Roger, who famously insisted "In defeat I need it, in victory I deserve it".
