Parker assigned a "drinking window" for the 1983 Pichon Lalande of 1997-2008. However, the bottle which Board-O & I experienced was "tired" and disappointing. Perhaps it was the "travel shock" from the plane trip to Oregon.
I have had two bottles from the same case last week and both were excellent and consistent. I do have one more in the OWC, but I think I'll wait till 2008 to open it. Also, I'm curious to see how that wine will be after Parker's 2008 window, perhaps in 2010-2013.
