R.D. Champagne

R.D. stands for "Recemment Degorge" - recently disgorged. Madame Lily Bollinger invented the idea in the 1960s: age a Champagne twice as long as a normal vintage wine, then disgorge it just before release rather than years earlier, so it reaches the customer with both real age and real freshness intact. Bollinger was also the first house bold enough to print the actual disgorgement date on the front label.
