Variance Within a Bottling?

Elsewhere, Drew didn't care much for a Zin which my chums and I think is quite the cat's pajamas. That made me think (yes, a rare occasion).

There are numerous variables which have an impact on one's response to a wine. But I wonder, since wine making is not as uniform as the manufacturing of Coca Cola, how much variability have y'all found within one specific wine?

I'm not talking about something so dramatic as a bottle being corked, but inconsistency due such things as the wine's tanks or dates of bottling.

Naturally, the wine's handling after being bottled (sitting on a hot loading dock, for example) has a crucial impact on how we taste it.
