I have had both the Bollie and the Ellner you refer to and feel certain that if the Bollie does it for you, the Krug will prove sublime. Again these are bubblies with some balls and not of the "...light and airy favorites..." variety all too commonly found out there nowadays. The grandest Bollie of all is an exceedingly rare offering called Vielles Vignes Francaise. It is 100% pinot and only about 200 cases are offered worldwide annually. In all my years I have only had two bottles, but that's just as well 'cause it will set you back more than Cris. But let me tell you, so terroir driven and flinty is it that its like swishing a mouthful of dirt around in your mouth [and this is the highest compliment I can bestow upon a champagne]. This is what sets France apart from the domestics--- its soils and the chalky/flintiness of them come through to add a depth and complexity or completeness to the flavor experience that I have not been able to corner in anything from the states.
Incidentally, don't be pushed to popping the cork on this Krug prematurely just because of all my carryings on. It, like all Krugs and Salons, will definitely improve and develop with age over, at least, the next decade or longer. However, at my house the flutes start levitating out of the cupboard almost as soon as the car door closes and the wine has entered the rack so any pretense of patience is demonstrably not one of my virtues.
Enjoy!
