Fair enough, we've had fun playing with whether or not you can set meaningful standards.
Let's take a moment to talk about whether or not setting such standards is a good thing, leaving aside the issue of how easily you can set them.
We had a government that decided that setting standards for winemaking in BC would be a good thing. They dictated a set of winemaking standards and said to the wineries - "If you adhere to these guidelines, you can join the Vintner's Quality Alliance, and you can put the VQA symbol on your bottles as a marketing inducement guaranteeing the consumer that you have used good winemaking practices.
They way things worked out, the adherence to the basic winemaking rules did NOT ensure quality wines, and indeed many producers succeeded in making absolute crap, albeit not flawed in the way that ignoring the rules might have produced.
The very best wines made in BC are not VQA because the talented winemakers see no point in spending the money on joining, and perhaps they also wish, on occasion, to diverge from the practices that the rules would require because they believe that they can make a better wine by working outside the rules.
To be charitable, the VQA experiment could at best be labelled a conditional success if one argues that it may have excluded some truly abominable wines but in fact it has had luttle effect in elevating the general level of winemaking in the province and the very best attainments have been quite independent of government intervention.
I saw the same thing when I was visiting winemakers in Bergerac this Spring. God knows the French are mad keen about setting rules, and forcing people to strictly follow to them - they are worse than a bunch of retirees on a condominium council (and those, let me tell you, are some of the most stifling mini-bureaucracies I know).
These winemakers told me that they cannot make a wine in certain areas that is as good as it can be and still toe the line on one of the stipulated parameters, alcohol content - their best wines are always slightly above the government guidelines (these rules can be very specific about how the grapes must be cultivated and the wine made). What the good winemakers do is to submit their wines to the authority, get the answer that the wines are not suitable for labelling under the AOC (in the case in point, this was Saussignac), and that they must label it as generic Bergerac. The winemakers slap their foreheads and say a Gallic 'woe is me' and then go ahead and label it as Bergerac as all their customers know their reputation and the quality of their wines, and it won't sell one whit more slowly for the lack of designation.
French bureaucracy is not
technically circumvented but the winemakers have in effect been able to flout the rules as they please and get away with it (I won't mention any names as you never know who might be reading!)
So there are two examples of how setting rules has failed to result in better wine reaching the consumer. Which makes me wonder why they should even try. I wonder what the situation would be if a libertarian approach were taken and anyone could do anything to the grapes as long as they were grown within the specified region. The good winemakers that produced a pleasing product would prosper and those that didn't would rightfully languish, all without reference to any arbitrary rules.....
