The best way to keep champagne fizzy is to use a champagne saver, which is like a cork but with a clamping mechanism that makes it secure to the bottle top, thus forming a seal through which the carbon dioxide cannot escape. This can be purchased from most wine merchants.
Tom Doorley, The Field’s wine contributor, suggests that although half-bottles of champagne can be problematic as they don’t keep as well, you’d be better off with halves as the less liquid that there is that’s kept open the better chance there is of minimal fizz loss. He recommends Berry Bros & Rudd’s own-label champagne, which costs £10.45 for a half-bottle. For further details tel 0870 900 4300 or visit Berry Bros & Rudd.
