"The first thing that you want to look at is the producer, and that'll be well laid-out on the front. You want to make sure that it's been made in Champagne, in France. Some bottles will be tricky, especially the French-made sparkling wine from other regions. Then, and this is one of the most important pieces, you want to look at where it says 'Brut' on the label. This can be very misleading for a lot of people; it's the part of the label where you're being told how much sugar is in the bottle. Brut, which is one of the most popular styles of Champagne in the world, is very dry. If you like something with a little more richness, a tiny bit more sugar, more generosity if you will, look for 'Demi-Sec.'"
