Collection represents a new paradigm for Champagne Louis Roederer, evolving naturally from the multi-awarded Brut Premier. This non-vintage champagne, born in a time of complicated weather conditions, stands out for its unique approach. Currently, due to the exceptional quality of the grapes and the use of biodynamic vineyards, Collection becomes a reference for quality and differentiation. It contains 44% reserve wines, including 4% of the Reserva Perpetua and 10% of regular wines, with the oldest vintage being from 2009. Its expedition liqueur of just 8g/L highlights Roederer's characteristic freshness while adding complexity comparable to the Vintages of other houses. Each edition of Collection is marked by the corresponding harvest, allowing remarkable diversity between each year, enhancing the consumer's experience. In summary, Collection symbolizes a release from traditional conventions of non-vintage champagne.
