Larmandier-Bernier Terre de Vertus 1er Cru NV - Non-dosé; 100% Chardonnay from Les Barillers and Les Faucherets in Vertus; too expensive at 50€
Expensive, perhaps, but awesome. I haven't had enough Champagne recently so I don't anymore have a proper reference frame to put this in, but it seemed to me to be a delightfully bready and steely and mineral fizz; crisp and pure but not unfriendly. Just the sort of elegance I like in my fizz! It's a pity that Champagne prices have risen so much here that I can't really justify drinking them.
I forgot to check what vintages this officially NV wine really is (sorry!).
