This is a good example of how the real issue becomes diluted. Z, I respect totally your right and desire to pick apart and argue on multiple points as you see fit, and I will respond as best I can to some of them, but it does again dilute the issue at hand as I see it, which is - most importantly - the Baumard 2012 harvest from the Quarts de Chaume vineyard.
Some points you raise and my responses:
With regard to developing an understanding of cryo-extraction, I think you need to look for more impartial sources of information on the technique than Florent. I like and respect Florent and hold his father in some regard; he in particular has done much for the Quarts de Chaume appellation, and his book (although hard work - only available in French) contains everything you need to know on the history of the appellation. Nevertheless his account only describes how he sees it, with his choice of supporting evidence. hardly impartial; there are plenty of other sources out there for that. Some sources say very different things to the Baumard explanation.
With regard to my Castéja/Baumard comparison, you are having a hard time understanding the ‘distinction’ because I didn’t make one. I merely made the point, to highlight the fact I do not have an inherent hatred of cryo-extraction, that I had tasted many wines where cryo has been used and I would never have known. Castéja is just one of several Bordeaux examples I could have cited, but he is an easy one as he is so open about his use of the technique. I gave what little data I have to highlight the fact that Baumard uses it quite differently to how most people use cryo-extraction; it is not fine-tuning, but the defining step in making the wine (in at least one/some vintages). It’s up to you to decide how you feel about that. If you think 80% water removal from the harvested fruit is OK, that’s fine by me. Buy and drink the wines. It isn’t a wine I would buy, but if the cryo has been used legally then I see no problem with it.
Baumard’s wines are, by the way, often delicious. I have a few vintages in my cellar. Nevertheless, if you taste a line up from the same vintage you can see, as I did last year with the 2007 vintage, that the style is different, but the distinctions are subtle. But as other posters have indicated, there is more to wine than what is in the glass. I like to understand what I am drinking, as it can enhance my pleasure. I would like to understand, for example, before I put my lips to the glass, whether I am drinking a botrytised sweet wine, or an ice wine; the appellation should guide to that. Where the line of distinction between cryo-touched botrytis wine and cryo-defined icewine should be drawn is impossible to determine; but I know 10% is very different to 80%.
As for INAO regulations, these are clearly written, easily available online, and must be adhered to in order to have the appellation. You don’t need to be an INAO official to see that.
With regard to wine data, I find your response very unusual. Having asked many winemakers for data many times, when one suddenly regards such data as a secret it is, to me, remarkable. You can spin the “Baumard doesn’t report to me” line if you want, although at not point did I intimate that he did. You are quite right, he does not report to me. If he did, I would insist the information was given. But I have not; I asked face to face, and he couldn’t remember (in itself unusual if you grasp how important these figures are in winemaking) and he invites me to ask again. I did so one more time, and received a blanking email with no meaningful information. I find the position taken by Baumard unusual and noteworthy in itself (and you don’t - fair enough) nevertheless for me that is the end of the questions, so do not cast me in the light of a pitchfork carrying mob member. I have only asked Florent the same questions I asked Jo Pithon, Claude Papin, Matthieu Baudry, François Chidaine, Jacky Blot, Vincent Carême, Vincent Ogereau and Yves Guégniard among others, al of whom happiky threw out numbers for yields, ripeness and residuals off the top of their head without batting an eyelid. In addition, I have posted here giving factual data and personal opinion, an account of the questions asked and the answers given. I find your pitchfork analogy to be inappropriate at the very least.
As for the issue at hand, for me it remains the 2012 Quarts de Chaume harvest. I have seen the images of the fruit, I have learnt what quantities were made by Baumard, I have learnt when Baumard picked, I have first-hand accounts of weather on the Quarts de Chaume in 2012, and I have first-hand data from other winemakers on the analyses of the fruit. For me, it is plain - no matter how much obfuscation there is from the cryo debate (and please feel free to carry on with it - don’t take my belief that it clouds the issue as some sort of indication you should stop) - that Florent Baumard has made a miracle wine in 2012. That is the really amazing thing here. The questions should not be “is cryo wrong?” because that will never be agreed by all - we all have our own opinions - but the question I would like to know is “how have you done it Mr Baumard?” In a vintage where everybody else fell by the wayside, he has made - looking at the published figures - about 10,000 bottles. Aren’t you at all curious to know how he has managed that?
