I'm unclear on the difference(s) here.
The original version in this current subthread makes it clearer. But let me see if I can harden the distinction. Remember that this is only a personal shorthand, not something meant to be a meaningful (or Meaningful) contribution to wine thought:
Lower-case "natural" means trying to make whatever seems like "natural" to the winemaker and within the boundaries of sense and common understanding, and might be seen as a synonym for "more natural" or "as natural as possible." Trying to do less until such a point is reached that a clear gulf exists between methodologies, or philosophies, or whatever one wants to call a given set of actions.
Upper-case "Natural" means making sure everyone, and most especially those who make wine the same way that you do and those who buy wine made the way you do, is aware that you make "natural" wine, and how you make it, and why. It doesn't really say much about the practices themselves, which may be identical to anyone's in the above category, as it does one's intent to use the open knowledge of them for a purpose beyond growing grapes and making wine.
One is a practice, or perhaps better a desire. The other is an identity and might even be a set of rules. It's like the difference between making a California wine from traditional Rhne grapes and calling yourself a Rhne Ranger (or helming the group). It's the difference between being pleased to learn one's wine is on the shelf at Terroir and visiting Terroir to explain why one's wine should be on their shelf. This is all very reductive, but it's in the ballpark with the distinction I'm making.
And none of it means the word "natural" isn't still fraught with problems in this sphere, even aside from the pushback it seems to engender.
The answer to the rest of your questions is yes/no/sometimes. You probably shouldn't try to divine how I feel about "natural" wine from this thread. My feelings are complicated.
Some of the lower-case Piedmontese producers may be conditioned by the fact that there is quite a bit of blatant Greenmarketing going on there, the talk without the substance.
That seems to be the expressed crux of their (and some journalists') complaints, yes, though they're a little shy on specific blameworthy targets when pressed. And to be honest, there's no way to differentiate this sort of suspicion from the similarly-expressed suspicion of whatever a given producer isn't doing. As mentioned in an earlier post, among the things described to me as "stupid," "idiotic," "insane," or -- my favorite -- "impossible" over the last week: native yeast fermentations, organic farming, biodynamic farming, Cascina Tavijn, the use of non-native grape varieties, Gaja, micro-oxidation, low sulfur, no sulfur, grignolino, Giacosa (really!), adding tannins, removing tannins, fixing color, not fixing color, bottling in any season other than winter, concrete or cement, barriques, and the internet.
That last one, at least, was right.
But within the group of people who actually do the work [..] I don't often see the questioning of motives or sincerity.
Sometimes of fidelity, though.
