Sounds like my kind of event! I have a similar "event" here at home only because champagnes make up 95% of my entire cellar except I don't have the courage or diversity to open 20 different ones at once.

Instead it's just called, "choosing a bottle and savoring it by itself with a special someone", which in all honesty is how I think champagne is best enjoyed.
But looking at the list, I find I agree with most (at least those of which I'm familar enough to even have a thought one way or the other...)
I agree with #1 yet I find personally I'm not exclusively loyal to ONLY Krug. For me there is Salon for example too

. Of course I wish I could say I have more bottles than I do resting in the cellar but when I HAVE had it, I'm not sure I could put the Krug above it. I also enjoy the more "commercial" but yet pure seductive pleasures of, say, Taittinger Comtes de Champagne and such wines. I also realize I'm probably more "chardonnay-seduced" (especially when aged) than most champagne lovers so maybe that explains the previous addictions. So while I'm one to agree that Krug is something uniquely special, I can't quite say that some others haven't, on ocassion, brought equal to greater pleasure. But aside from all that, yes, I always have the 375 halfs of Grand Cuvee stocked as sort of my "house" NV champagne (just because it's one of the really NICE champagnes in HALF form I can find in numerous quantities typically). And they are a pleasure to age. I try to keep sort of a progressing ladder stock of them going where I try to pull out the oldest halves I purchased while sporadically re-stocking a handful of new ones so that I'm always, hopefully, pulling out "older" ones to consume at any moment. I try to do this with my other favorite "commercial" NV -the Laurent Perrier L.P's as well. A much easier and CHEAPER adventure with the latter! What always stands out as unique to me about Krug for some reason is the "lemon component". Meant in my experience as a seductive/positive thing. I seem to only notice it in Krug (Grand Cuvees). Most champagnes it's inherent to find "citrus" or of course "apple". But I find what I consider more true "lemon" in Krug. It's a bit more of a heavy/smooth/rich subtletly of the citrus that I pick up on in many Krug's than just the usual, sometimes sharper citrus profile which is the normal champagne profile, especially when younger. I don't know if it's just me or just a random impression I've had a few times just with Krug but I swear they can often taste more lemon-y to me than other champagnes, in a pleasing way.
For #2, it sounds like I should not be in any hurry to try the two 2000 Dom's I have. But I wouldn't doubt that after 9 years it likely isn't at its most enjoyable yet. I have a half case of Perrier Jouet Fleur de Champagnes 2000 and found the same thing - just very "green" yet to my tastes. But I couldn't resist uncorking just one to see. But I should know better to do that with any champagnes! I have a predominately "english taste" in champagnes. I almost can't have one too old unless it's flat-out dead or outright sour. I LOVE the caramaled, slightly oxidative, lazied-bubbles, nutty taste when it comes to champagne and thus I typically am one who never even ponders having ANY vintage champagne, if I can resist it, from about 15 years from the vintage. I know several are "fine" to drink before then but I TRY to wait (or purchase somewhat older to begin with if I can afford it) until any "greenness" is thouroughly gone (at a minimum). But I know tastes are different. It's just that when I have had "subpar" champagnes, I can almost always trace it to the fact that I simply opened it too soon (for my taste). So I've started to learn my lesson on the "getting too curious for my own good" mindset with vintage champagnes. I now have an automatic 12-15 year counter in my head from every year I see on any of my bottles. I stop and count at least 12 or so from the year I'm looking at. If it isn't at least 12 years I don't even ponder it anymore. Of coures roses and non vintage are a more "flexible" adventure. And in the case of non vintage, without disgorging dates, who knows how old it is when you purchased it to begin with? All you can do is pop the cork and hope it's great! Yet even with NV I find my favorite bottles (even with those supposedly ordinary, commercial, Laurent Perrier Brut LP's) have always been ones that were significantly (and safely) aged prior to me purchasing them! Yummy! When it starts to taste (or look) like the profile of caramel apples I know I hit a favorite one!
#4 is one I can't really comment on either way. I honestly haven't the pleasure (or is it apparently not a pleasure?) to have a Cristal before. I can only guess this has been a combination of two things... 1) my INITIAL experience with Louis Roederer in general was not my "style". It turns out that I just had "off" bottles of the NV I think. But it set an initial tone that kinda kept me away from "getting into them" too much. 2) the bottles, even NEW, are sooooooo high that it never inspired me to gamble on one, especially when my early opinions were that Roederer isn't my style to begin with. I have no problem sporadically splurging on a Salon or Comtes de Champagne since I know I like those and will cellar them anyways but I never could force myself to try a Cristal. Not yet anyways...

For what it's worth, I finally did have a truly delicious and balanced Roderer NV recently! It turns out I was wrong - Roederer can be delicious, apparently. But the Cristal is simply uncharted waters (or is that bubbles) for me...

#6 is an interesting one. I do agree that I'm one who's never seen the "charm" in the Billecart-Salmon Rose. Have tried it twice before, one half and one full bottle. Like the initial Roederer NV, maybe they were just both "off" too? But both were very "un-substantial" to my tastes, almost too "airy" and yet kinda on the sharp end rather than balanced/seductive end (to my tastes). It just didn't seem to hold what I think makes ideal rose champagnes great to begin with. Oh it wasn't "bad" or undrinkable. It was "nice" I guess. But I guess it just wasn't my seductive idea of a great rose. I also simply think I may just be a bit bigger fan, generally speaking, of just the traditional "blonde" champagnes. That could be a lot of it. Yet the 1988 Dom Perignon Rose was one of the greatest champagnes I've tasted! Much more mouthfeel, hints of strawberries and cream and definitely "seductive" rather than slightly sharp like the Billecart Salmon or other NV roses I've had. I guess THAT is my idea of a rose champagne but also understand it unfortunately isnt an everyday pleasure to drink. But don't I wish... Anyways, I DO love roses! But just find, based on the above experiences, that I have a hard time finding "everyday/commercial/non vintage" ones that woo me fully in the way I think roses are "supposed" to. This is somewhat true just with ANY champagne as it's often, like anything, a "you get what you pay for" kind of thing. But I find it particularly true with roses, in my experience. On the other hand, I HAVE had a few non-commercial, less expensive, NV blonde champagnes that were up there as the greatest champagnes I've thus tasted...
I also agree about #11 unfortunately. It's still my favorite wine so I'm guilty of often splurging on whatever prices get asked. What choice do I have? But I agree that it would obviously be nice if they were going DOWN rather than up! Especially somewhat surprising seeing the state the world economy is largely in too! I still get catalogs from my favorite champagne stores in the mail and keep expecting to see all these wondrous wines having sharp discounts or deals but, ironically, many seem to be just the opposite! I guess it's the chicken or the egg thing. The customers now can't afford many of them yet because customers aren't buying, the places also can't afford to sell them at discounts, or even just at regular prices! In other words, I guess EVERYONE and EVERYBODY is currently broke!

This is going way off topic now, but I notice similar things in general even with the holiday shopping etc. Maybe I just am not loking in the right places but you'd think in these tough economic times, deals/discounts would be off the charts. Ironically, I've found the opposite so far - no real eye-popping deals or typical grand holiday mega-deals etc. Sure, the ads and commercials still "advertize" that they are but if anything, I get the idea that the STORES are just as broke as the consumers and actually aren't giving the kind of discounts/sales that you'd initially figure would be common sense in this economic environment. Again, I think it's the chicken or egg thing. Also proof, I guess, that just one segment being broke can effect EVERYBODY (in some fashion) since it's like an epidemic that spreads to all segments of the economy. But enough of this "real life" babbling on my part. Back to the bubbles...

Lastly, and most importantly, I think your #12 is the best one! And glad to see there is other fans of what I think is the most special wine on the planet!
