It might(?) not be illegal to label sparkling wine made in california as such, but I don't believe I've ever seen labeled as such. It is not uncommon to see "method traditionale champagne" or similar in smaller print somewhere on a bottle of California Sparkling though, but it's not part of the primary labeling. We've been buying cali sparkling and french champagne on the semi-regular for a couple of years now and I've only seen french wines use/claim the title of Champagne. Mumm Napa makes fantastic sparkling wine though, and is widely available all over northern california for $20-22/bottle in several varieties.
