Champagne's geographical location engenders capricious weather. For this reason, since their foundation in 1849 Pol Roger have observed the tradition of not releasing a vintage-dated champagne unless the climatic conditions permit the production of grapes of outstanding ripeness. A vintage champagne must, above all else, be a balanced champagne. This balance depends on the right blend of healthy grapes, a good potential alcohol and correct acidity. The first criterion for declaring a vintage wine is its capacity to age. Devotees who have the patience to age their champagnes are rewarded with a more complex and richer wine.
