We drink a lot of Champagne in our house. In a typical week, we open 2-3 bottles. Typically they are entry level Champagnes, usually less than $40/bottle. Occasionally we drink more expensive stuff. The last three times I've been served Veuve yellow label (two of those times, it was served blind, so there was no label bias involved) I have literally poured it down the drain because I found it undrinkable. No hyperbole involved.

And, for the record, I quite like aged Dom, but there are many less expensive Champagnes with much less famous labels that I enjoy at least as much, especially when consumed within a few years after release.
