Saving champagne is an art that tantalizes all wine lovers. One needs to know the correct ways of preserving the tastes and keeping the fizz that sets champagne apart.

One method often used is utilizing a 'bouchon conservation', a specialized device designed to keep champagne. The 'bouchon' works by forming an airtight seal, blocking the gas from leaving, thus keeping the bubbles and tastes that are so characteristic of champagne.

An important factor to consider when keeping champagne is the 'temps conservation' or the duration of keeping. Like all wines, champagne is a product of Mother Nature and is susceptible to changes from its environment. In a perfect world, champagne should be consumed just after opening, but if that's not plausible, it’s important to know how to maintain its taste and fizz.

Storing champagne in the refrigerator, or 'conservation champagne frigo', is another practical method. But, too long in a cold environment can diminish the wine's characteristic. The fridge must be set at a reasonable temperature for the champagne to preserve its taste and sparkle.

The 'garde du champagne' or maintaining the champagne requires utmost accuracy. Both temperature and humidity is crucial in preserving the champagne's qualities.

When it comes to the temperature of 'conservation champagne', the ideal temperature is generally light chilled, around 7 to 9 degrees Celsius. Too high or too low temperatures can affect the taste.

The 'durée de conservation champagne' or the duration of preserving champagne can extend from few days to years, depending on the quality of the champagne. However, once the bottle is opened, the duration decreases drastically.

For 'conservation champagne ouvert' or opened champagne, it is best consumed in 3-5 days of opening to maximize its flavor and fizz. After that, the champagne starts to miss its conservation champagne ouvert characteristics.

Finally, the use of a 'bouchon pour conserver champagne' or a champagne stopper is an essential tool for preserving champagne. This tool is designed specifically to match champagne bottles and assist to maintain the fizz and taste.

So, whether you're a rookie or a seasoned champagne lover, knowing the correct methods of champagne preservation can improve your drinking experience significantly.
