Hmmm, yeah. I don't get grassy either from Bollinger, but yes, sweet caramel, almost a caramel apple kind of flavor.
Interesting, Otto, that you tried a basic Chardonnay style of Champagne and then went with a heavy-up Pinot Noir style like Bolly. Pretty much the extremes on the scale.
I've been hearing mixed reviews on the 1999 GA. The 1990 and the 1996 are absolutely stunning bubblies, some of the best I've had in a long while. Wish I could afford to drink more of them.
