In the US ~ particularly California, most sparkling wine is made using only Pinot Noir and Chardonnay grapes. Champagne undergoes two fermentations, one in the tank/barrel, etc. and the second one takes place in the bottle ~ this is the 'method champenoise' or traditional method. Sparkling wine can also be made in the Charmat method (in tank for the second fermentation), and then bottled/corked afterward.
For a quick, fun look at the sparkling wine process here is a video from Schramsberg, in California.
Don't forget to celebrate this day with a bottle of Bubbly ~ you'll be glad you did!
