Taking care of champagne is an art that tantalizes all wine lovers. One needs to know the correct ways of preserving the flavors and preserving the fizz that sets champagne apart.

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

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

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

The 'garde du champagne' or maintaining the champagne demands utmost precision. Both temperature and humidity is crucial in preserving the champagne's features.

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

The 'durée de conservation champagne' or the duration of preserving champagne can extend from few 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 inside 3-5 days of opening to maximize its taste 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 created specifically to fit champagne bottles and assist to maintain the fizz and flavor.

So, whether you're a beginner or a seasoned champagne aficionado, knowing the right methods of champagne preservation can enhance your drinking experience drastically.
