I am throughly convinced that the most you should ever spend on Champagne is 50-80 dollars (ex a normal bottle of veuve clicquot), and only in extra special circumstances go near the 200 dollar price point. Anything above that is just paying for style over substance.<p>Specifically I taste tested several bottles based on an increasing scale of rarity and price. This included a 200 dollar bottle of dom, a 200 dollar bottle of La Grande Dame, and a one of a kind bottle of Dom stored properly in my friends basement since 1988 (a supposedly good vintage).<p>I have no skin in the wine game. I just don't like getting tricked by the luxury business. 50-80 is the sweet spot of quality and price, with diminishing returns in quality at the 200 price point Once you get above the top recent vintages, you are just paying for exclusivity not the product.
