Inky - I was under the impression that Sablefish, Butterfish, and Black Cod all refer to the same fish. I didn't realize that there was a difference with the three varieties. My fishmonger labels it Sablefish, and it is always incredible.
Aries - I am aware that this wine falls into the WB age group that was susceptible to premox. I will definitely have a backup ready (2001 Leeuwin Estate Art Series), but quite frankly I think a little premox (as long as it's not out of hand and the wine is completely brown) has added some nice complexity to some WB's from the aforementioned age group that I've been lucky to try.
