Pol Roger founded his Champagne house in 1849 and it is still proudly independent, under family control. It owns 89 hectares of vineyards on prime sites of the Vallée d'Epernay and on the Côte de Blancs. Its cellars run for 7km and are on three levels, the deepest known as the 'cave de prise de mousse' at 33m 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 9oC or less rather than the normal cellar temperature of 11-12oC prolongs this fermentation and contributes to the quality and particular style of the wines and their famously fine bubbles.
