I was thinking about this a few weeks ago after I went to a sparkling wine taste at Binny's. I for one do enjoy it a great deal. My girlfriend and I drink it quite often. It is probably 2nd or 3rd behind Bourbon, and whisk(e)y in general and beer for me. I probably do drink sparkling wine more then beer. Its something that my girlfriend and I can share. She won't drink bourbon, or any other whiskey, and I don't drink red wine(makes me sick for some reason, even a little gives me a headache), but it is something we both enjoy.
We drink all kinds, but I think Italian Sparklers are our favorite. Also they offer a great value. Prosecco, and d'Asti(Brachetto, Moscato, Blend) are excellent. There are many brands that have excellent offerings of these varietals. Domestic sparklers also offer some good value especially Domaine Ste Michelle from Washington state. Of course Champagne, although not as often because of price. But Piper Heidsieck, Moet & Chandon, and Nicolas Feuillatte have good offerings under $30-$35. St Hilaire from France is also very good and under $10, though not from Champagne. Spanish Cavas are also good.
Just wanted to see what people thought.
