Sparkling White Wine
Champagne is from France, so if you make it in California you have to call it something else. Sparkling white wines can come from anywhere in the world, but typically refer to those produced outside of Europe. The best are produced the same way Champagne is, using the same techniques and grapes. Unlike with Champagne there are no laws in place to assure a minimum degree of quality, so the variation between wines can be significant. Sparkling producers in California founded by Champagne houses often have the highest quality, but your best bet is to find a wine shop you trust and let them talk you through it.
