If you're looking for a fine, but reasonably priced Champagne for the holidays this year, I recommend this new-ish offering from the famous Champagne house Taittinger. It's made entirely from Grand Crus-rated vineyards (ones that score 100% in the Champagne AOC's system), and it's 50% Chardonnay and 50% Pinot Noir. it's got great structure and length, but is marked by an elegance and a citrusy juiciness that makes it hard not to guzzle. I think the price of $50, which you can find at K&L, is a bargain for Champagne of this quality.
