Variety?

Has anyone noticed an inconsistency between bottles? I found it to be pretty drastic at times. Usually it's just amazing even with a slight change in flavor, but once in a while it's a bit off the mark.

Recently I had one of those bottles. It seamed a bit more watery, had less pulp and didn't have that zing, I was used to.

Like a good wine, I know you get some variety, but I find it disappointing, especially at a tasting.
