I love wine pretensions and employ them myself. I have a few bottles of Dom Perignon Rose 1999 and when serving them I use white wine glasses. I do that despite the wildly pretentious air it conveys because the older rose champagnes seem tastier when they are allowed to open. Others can describe the reasons and establish the logical basis, but i do it because it tastes better that way. I do the same with a handful of others but they are all older rose sparkling wines.
