Taking care of champagne is an art that tantalizes all wine lovers. One has to know the proper ways of guarding the tastes and maintaining the fizz that sets champagne apart.

One method often preferred is utilizing a 'bouchon conservation', a specialized equipment designed to keep champagne. The 'bouchon' works by making an airtight seal, stopping the gas from escaping, thus maintaining the bubbles and flavors that are so characteristic of champagne.

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

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

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

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

The 'durée de conservation champagne' or the duration of preserving champagne can extend from several days to years, depending on the kind 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 lose its characteristics.

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

So, whether you're a novice or a seasoned champagne lover, knowing the correct methods of champagne preservation can boost your drinking experience considerably.
