After the upheavals of the early 1900s, particularly the First World War that destroyed more than half of the Louis Roederer estate, Léon Olry Roederer reconstructed the vineyards. He decided to buy grapes to ensure the continuity of the House during this difficult period and, at the same time, created a multi-vintage wine that would have a consistent flavour, whatever the harvest year. It is now called Brut Premier.
