Like to know what's in Grange? Most years Penfolds has to break the law to tell you

Grange. Australia's most famous wine. The red that put our country on the world's quality wine map. Yet most years Penfolds has to break the law to tell people what's in it.
If you think that sounds like madness, well, yes, it is. Yet Wine Australia, the federal government body that controls how wine is labelled and promoted does, outlaw telling the truth about Grange and many other wines blended from different regions.
This is the idiotic bureaucratic regulation that defines the offence:

And the section of the Australian Grape and Wine Authority Act 2013 that the regulation refers to:

The problem arises because the grapes that end up in Grange regularly come from more than three regions as the company website explains.

So Penfolds is in breach of the law with this reference in its tasting note for the 2010 Grange:

VINEYARD REGION Barossa Valley, Clare Valley, Adelaide Hills, McLaren Vale, Magill Estate

Oh no! Five GIs mentioned when you are only allowed three.

I wonder if and when the regulatory bulldogs of Wine Australia will threaten Penfolds chief winemaker Peter Gago with jail like they have the proprietors of that little Baross winemaker glug.com.au?
