One of the most insidious myths in American wine culture is that a wine is good if you like it. Liking a wine has nothing to do with whether it is good. Liking a wine has to do with liking that wine, period. Wine requires two assessments: one subjective, the other objective. In this it is like literature. You may not like reading Shakespeare but agree that Shakespeare was a great writer nonetheless.
You could say one wine is like Dorothy in the Wizard of Oz while another is like the mature Judy Garland, or that a big voluptuous chardonnay is like Marilyn Monroe -round, bosomy - you can remember that chardonnay, If you say a wine is snappy and lively, like Robin Williams, that's very different than the Anthony Hopkins of wine - urbane, sophisticated, measured, considered.
A wine is ready when you can't bear to wait for it any longer.
