I imagine champagne is like many other bubbly beverages. Much like a good beer once chilled it should stay chilled. it the bottle stays chilled I imagine it keeping for ever. Let me warn you though, once it warms up, chilling it again can and will do just like a beer that has been rechilled, it can get skunky.

Yes, but try to limit the amount of times that happens.
Since champagne is chilled, the surface of the liquid once opened chills the air to it's dew point creating what is known as the "Heather" of the champagne. French people from Reims in the Champagne region believe that breathing in this Heather has a rejuvenating effect on health

Champagne should be chilled in the fridge for at least 2-3 hours before serving to reach the optimal temperature of around 45-48F.

I think please review the question. Are you asking for champagne or cognac??? Champagne is served chilled whereas cognac is served at room temperature(if drinking neat) or served alongwith warm water.
