Chris - I believe most of the Bouchard range is under DIAM. I thought I had heard the same re Jadot, but have not bought or seen them in my market for ages.
Don Cornwell deserves mention in this thread. On two fronts, he has helped tremendously with the issue. He started the oxidized burg wiki and his yearly white Burg dinners are very comprehensive and published on this site, affording much valuable information. He also works behind the scene with conversations and recommendations to many Burgundy winemakers. He has been instrumental in education on many fronts including Diam and other closures. The rest of us gripe; Don actually does something and we owe him a great debt. Chapeau!
My understanding is Bouchard and Jadot and Fevre (for somewhat reasonable) and Leflaive (for completely unreasonable) at this point.
I would be interested in which others, if anyone knows.
I have not checked Don Cornwellās site for a bit to see whether that up to date info is listed thereā¦and I have to look up the latest website address since it changed, unless someone has it at hand.
Found this info on Don Cornwellās Oxidized Burgundy site, I think updated sometime in 2018:
"Domaine William Fevre began bottling a portion of its Chablis (the 1ers) with DIAM in 2007. Starting in 2009, all of the Fevre production except for the grand cru Chablis moved to Diam.
Beginning withe the 2009 vintage, additional producers begin using DIAM closures. Bouchard Pere et Fils (Bouchard and Fevre have common ownership) moved all of their whites to DIAM beginning with the 2009 vintage. Domaine Montille, Deux Montille, and Domaine de Chateau de Puligny Montrachet (all related brands), along with Javillier and Roger Belland have bottled all of their white wines under DIAM starting with the 2009 vintage.
F&L Pillot joined the DiAM parade with the 2010 vintage and Fevre began bottling all of their grand cru Chablis with DIAM corks.
Jadot, Domaine de Bellene (and Roche de Bellene) and Droin (in Chablis) began using DIAM for all of their white wines in the 2011 vintage.
Starting with the 2012 vintage, Olivier Leflaive and Jean-Marc Brocard in Chablis began bottling all of their whites under DIAM closures.
Starting with the 2013 vintage, Lafon, Prieur and Chanson began using DIAM for all of their whites (except, in Lafonās case, the entry level Macon that is sold in Australia, which is bottled under screw cap). Lafon is using DIAM 30 (intended to be used for wines intended for 30 or more years of bottle age). Prieur is using DIAM 10 for the village and premier cru wines and DIAM 30 for the grand crus. Chanson began using the new DIAM 30 on all of Chansonās top wines. Bouchard Pere also immediately started using the new DIAM 30 for all of its whites when they became availble.
Starting with the 2014 vintage, Domaine Leflaive is bottling all of their wines with the new DIAM 30 corks. Daniel Dampt is bottling 90% of their production under DIAM. According to Dampt, the remainder are being bottled either under screwcap or natural cork, depending on the importerās preference.
Starting with the 2016 vintage, Marc Colin and Maison Harbour are bottling their whites under DIAM 30.
Starting with the 2017 vintage, Pernot is bottling its wines under DIAM.
Both Sauzet and Roulot use DIAM closures on their Bourgogne Blanc wines. Raveneau bottled the 2013 Chablis AOC under DIAM."
Appreciation has not changed though buying habits did. Price was also a factor.
I have also back-bought WB at auction for certain wines where I did not experience premox 15+ years after vintage. There are some buys out there for the patient.
Respectfully disagree with Mark that there are real alternatives to WB. There are certainly different and profound and complex white wines that age remarkably well; they are just not WB.
And Iām nearly certain I have a bunch of premoxed 2004 Fevres that Iāve been ignoring.
Yes, youāre correct John. There are so many producers (and new ones all the time) that it is hard to keep up with what type of cork they use. I happen upon them by accident when opening them. There is no indication on the label or capsule that the cork is different, unlike the screw-caps or glass-locks. If DIAM is such a superior method of closure, you would think the company name would go somewhere on the bottle.
But isnāt 15 years pushing it for a white wine that isnāt labeled ārieslingā? I sort of assume some whites I open over 10 years of age outside of certain categories will begin to slow down and fade a little, with some of that giving various degrees of oxidized notes.
Same for me. Iām willing to backfill certain producers that did not experience significant premox issues and have been reasonably (though not entirely) successful.
A well-aged white Burgundy should show some degree of oxidized notes, if by oxidized notes one means honeyed color and honey, nuttiness, caramel, butterscotch, and similar flavors and aromas. I find that many people who started drinking during the premox era tend to mistake any sign of oxidation as premox and not as a natural and desirable part of a wineās evolution. A key difference is that with a well-aged wine, there is freshness and vibrancy along with the caramel or nuttiness.
Having already committed to cellaring them, the premox phenonemon, if anything , has increased my appreciation of White Burgundy. Though Iāve had my share of premox (and not as much as I expected), it has helped me realize how great an aged (your criteria, but 15+ years) offers a great experience and wonderful payoff. The flawed bottles donāt affect that āappreciationā. They do piss me off, etc. But, Iām really glad to have a stock.
I am firmly convinced that the culprit is the cork: that they have been kilned irregularly and in many cases, way too much (too rigid) to hold a good seal at the bottle neck. Nothing more complicated. Which is why I find the diam issue of interest. But, in a way, that preserves them rather than allows them to ageā¦a different process.
I stopped buying in 2007, at my wifeās urging and with no regrets (other than Iāve also lost much of my interest and, certainly havenāt kept current. Having a superb , aged WB (including Dauvissat Chablis)ā¦only makes me realize how screwed most of us consumers have been. And, the cork industry seems to have avoided all roundups and left the artisanally structured WB industry holding the bag and blaming themselves.
In addition to a lot of Riesling (including top dry ones), Vouvray and Condrieu often can age more than 15 years. And, once upon a time, Chablis and White Burgundy.
