Background information

In vintage 1996: batonnage known to have occurred, but frequency and length unknown.
In vintage 2003:“I did virtually no bâtonnage and I was afraid that they would take up too much wood so I racked them into stainless in May. During the élevage the wines ate a lot of SO2 and I decided to bottle with more CO2 as well.”
In vintage 2004: “considerable lees stirring until the end of the malolactic fermentation (and, in a few cases, even later than that.”)

Chassagne Chatenière (Oct 2010): not oxidised, but I was suspicious at first as quite faded vs bottles from a year or two ago. Cellar Tracker notes suggest that other tasters have observed the same thing. I think it is more a lack of acidity than premox. [CCN]
