International judges invited to far-flung wine competitions are expected to bring an interesting bottle to share with the other judges. So in Australia one year I brought a Grüner Veltliner from Jurtschitsch in the Kamptal that was over thirty years old. It had been given to me by the producer a year earlier. I poured it blind. None of the judges could identify the variety, and they all gasped with disbelief when I revealed the vintage.
