Jones- I would agree with you that 99.999% of ALL viognier is best drunk young (within a year of vintage date). I do know from experience that Calera can and should be aged, but I agree that the question of provenance is a very good reason to drink up this particular botle. Calera Viogniers when consumed young are extremely mineraly and that fades with age.
Otisabdul- Like I said above I agree with this opinion on most Viogniers but I was specifically speaking to the wine in question, which is Calera viognier.
Viognier is one wine that I really know and I know that I like Calera with age. To each his own.
