Dom Pérignon
Until the 1943 vintage, Dom Pérignon was produced from regular vintage Moët &amp; Chandon Champagne that was transferred to the special 18th century-style bottles after extended cellaring. It was, thus, effectively an "oenothèque" release of Moët &amp; Chandon Vintage Champagne in a different bottle. From the 1947 vintage, Dom Pérignon has been produced separately from the start.
