Storing champagne

[Shishir Baxi]

hello, i am an amateur wine lover from mumbai, india. i have recently been gifted a bottle of moet et chandon champagne. since the weather in my city is rather humid (though cool currently), and i do not have a wine cellar, i would like to know how to store this bottle at home and not let it go bad. i have currently stored it at the back of a wooden cupboard. thank you for any suggestions.<BR>shishir baxi
