Vintage or non-vintage, magnum or standard bottle, it makes no difference when serving champagne.

There is only one way. So armed with your bottle of Moet and a handful of glasses, prepare to enjoy. When it comes to storage at home, Moet & Chandon is really rather laid-back. Horizontal in fact. Unless you intend to drink your champagne within a couple of days, you should 'lay it down' on its side, in a cool place with a constant temperature (an under-stairs cupboard or cellar would be ideal). Kept this way, non-vintage should last for up to a year and a vintage up to five years.
