Two bottles here or there isn't really what I'm getting at.
It's the folks who buy 6 of this, 12 of that, and before one knows it, they've spend a couple thousand on wine they've read about, or tried a few vintages back and they're simply going on blind faith that it will be to their liking. My simple argument is...give it a try. Even if you liked the previous vintage. There's no guarantee you'll like the next one. '97 and '98 Insignia are not the same wine. '02 and '03 Clos de Tart are not the same wine. '02 and '03 Guigal La La's are not the same....etc., etc.
