Hey, anything that involves Olympic taste-testing is fine with me. As long as there's random drug testing along the way, just to make sure no one is taking unfair advantage.
Back to the subject, though, I'm willing to venture your confidence in this assertion is not unrelated to how many more red wines than orange wines you've tasted. Had you tasted orange wines in the quantity you've tasted red wines, I bet you'd be as quick to highlight their differences across varieties and sites as you are now to highlight their similarities. This is what Levi was getting it: from a sample set of two red Burgundies vs. several hundred California pinots, one might conclude that the Burgundies tasted pretty much the same, but be able to talk at some length about the differences between Gary's and Pisoni, and more generally about the differences between California pinot and Burgundy. Those who know more about Burgundy -- because they've tasted a lot more -- would suggest, with varying levels of force, that they not only disagree with the other's opinions, but that they're based on pretty flimsy evidence, and thus the likelihood that they're misguided is fairly high.
I once had someone refuse an Australian riesling because he didn't like sweet wines. Obviously, one is free to avoid sweet wines if one wishes. But anyone who's tasted many Australian rieslings knows that sweetness is hardly their signature feature, and that "I don't like overly acidic wines" would be a better-justified basis for refusal. In other words, the refuser was...well, "wrong" is a too-strong word, but certainly he was speaking without having any idea what he was talking about.
Nathan thinks skin contact obscures or obliterates terroir and varietal character. Nathan also thinks this about sparkling vs. still wines, and though I can't recall if he's said this I'd wager he also thinks it about sweet, and especially botrytized, wines. In the first two cases, since those are the ones I'm sure about, the likelihood of a respondent arguing with him, and the strength of the disagreement, went up the more they knew about the category...Peter Liem for bubbly, for example, or Levi for orange wines. That doesn't mean that Nathan is wrong, and at least we have a (digital) paper trail to follow his notes (which is what I haven't seen from you, hence my differing response; if you've tasted hundreds of orange wines -- which is entirely possible -- you haven't posted notes on them, and a casual search revealed not that many notes from the category, actually), but the more knowledge = more caution about broad generalizations trend is, to me, at least suggestive, and should be strongly considered whenever one is taking a firm position at one of the poles of the argument, as you are. That's my discussion with you; I don't understand how you've arrived at the conclusion, and it seems to me you merely restate the opinion (often posed as a "don't you think..." formation, but it's still something you obviously believe) without retreating to a foundation for the opinion. I don't want everyone to "show their work" about every subject, because that gets tedious, but since we're having a discussion about why you think this, it might be helpful in this specific case.
My discussion with Nathan is different. If I'm right about how he feels about sweet/botrytized wines (and let's say for the sake of argument that I am), then we can say that he only feels that still, dry wines can fully express terroir and varietal character without techniques getting in the way. (You, I believe, are on record as believing that only varietal wines really express terroir -- certainly you've expressed this to me in person -- though maybe you've since changed your mind). Both fairly reductive views. With Nathan, I'm trying to figure out what the basis for this assertion is. If it's skin contact, then why does it obscure terroir/varietal characters in whites, but via magic and chicken soup does not do so in reds? I have a very hard time seeing how that can be. And one could go on down this road until the only wine that can actually express terroir and varietal character without undue obscuration is a single-terroir, single-variety white wine with a controlled yeast fermentation (not necessarily inoculated, but one must have consistency) and raised exclusively in INOX, then put into container without added sulfur. I don't think Nathan would agree with much of that. Thus, my suspicion is that Nathan comes to the orange wine table pre-prepared with opinions about how similar they're going to be, and -- perhaps unsurprisingly -- finds this to be confirmed, and that his position isn't really based on a careful weeding of techniques into categories of deformation. I'm trying to find out if that's the case.
