I am thinking specifically of one producer's wines. Sometimes the standards are different. A wonderful facet of Burgundy is the variation in vintages. Some years produce wines with very high levels of tannin. Lighter wines or those which are drinkable in their youth tend to be maligned.
Good winemakers make good wines.
The rubes get lucky in a good vintage and are lost the rest of the time. Good winemakers are sensitive to the vintage and adjust their winemaking accordingly. Taste wines from vintages such as 1991 and 1992. This is where you can separate good winemakers from poor. It won the tasting, by the way.
