The six-day Win Australia 2000 show will have attracted 34,000 people by the time the doors close on Tuesday and will have showcased over 8000 Aussie wines. And it will have been achieved with amazing good grace. Large exhibitions are usually held in soulless caverns erected on former toxic-waste sites. But Wine Australia has been at the heart of Melbourne, a great city, and it has never felt either crowded or cavernous.
