The creation of Collection is  influenced by the introduction of a “Perpetual Reserve”, which began with the 2012 vintage and has been enriched each year with wines from the latest harvest stored in large capacity oxygen-free stainless-steel vats. Over the years, this Perpetual Reserve will be further enriched with new wines from each new harvest to create a template of infinite complexity, freshness and energy.

In parallel, Roederer has greatly increased the proportion of oak-aged reserve wines contained in the blends. These wines from previous years and young plots on the Cristal estate, aged in large French oak vats (foudres), are a Louis Roederer hallmark. They provide a perfect point of balance with the freshness created by the Perpetual Reserve, giving the wine greater intensity and honing its salinity.
