Thank you for the 2014 link, Jeff. Iâll peruse that later with a glass in my hand. 
On chaptalization not being secretive. Respectfully, Iâm calling b.s. on that one. I just spent some time trying to find that information for 2021, 2023, and 2024 online. I was only able to find bits and pieces; certainly no 2021/23/24 Bordeaux Chaptalization report, or something of that kind.
The authors of this article about 2021 Bordeaux said, âProducers can seem keen to gloss over or shy away from discussing the tricks of their trade. ⊠We asked about the potentially contentious topic at every property we visited, receiving only a small handful of slightly wary responses on the topic (âWe did what we had to do,â one winemaker said, with a smile).â That doesnât sound like producers are being terribly forthcoming on the topic.
Some producers were somewhat more forthcoming:
" At [Ch. Cheval Blanc Pierre-Olivier Clouet firmly stated, âWe never touch the natural balance of the wine.â That said, they did chaptalise three plots in the end, but none of them made it into the Grand Vin. Delphine Kolasa of Margauxâs Marquis dâAlesme believes that you can almost always feel a warmness from the additional, unnatural alcohol â although she noted a few properties who had managed it so well you could barely tell.
At Les Carmes Haut-Brion, Guillaume Pouthier highlighted the balance needed with the yearâs acidity levels. The relative lack of sunshine resulted in grapes high in malic acid, meaning that the malolactic fermentation (where hard, green-apple malic acid is converted into softer lactic acid) had a greater impact in the wines, reducing the overall acidity. With this in mind, he felt that chaptalisation could lead to wines feeling âflatâ â but it wasnât a necessity for him, given he managed to reach 13.5% natural alcohol thanks to the propertyâs warmer, suburban microclimate. âŠ
*But there were plenty of outstanding estates which felt it was an essential element to success in the year. At Le Pin, Jacques Thienpont remarked how they had to employ âforgotten methodsâ, noting that it was more than 20 years since heâd had cause to chaptalise in Pomerol. He used it on a couple of vats. *
JosĂ©phine Duffau-Lagarrosseâ the young vigneronne who has taken over her familyâs estate â joked about having to learn how to do it, so alien is the process to a millennial winemaker.
Similarly, Christian Moueix â another of the Right Bankâs old guard â noted how he used it almost every year in the 1970s, but hadnât needed to for a long time. For him the key was not to overdo it, enough to add a maximum 1% alcohol. There was a clear consensus on this among proponents â adding half or one degree (of alcohol) was beneficial, but if you pushed things too far, youâd lose balance in the wines.

I could keep searching and post many more similar comments/passages from other articles. While conducting my fruitless search for this non-secretive, yet oh-so-elusive Bordeaux Chaptalization report, I learned the practice has been banned in Bordeaux since 2019, and can now only be done by and through an application and approval process. Why ban something if itâs not âbadâ?
Iâm sorry, Jeff, but you simply saying this information is not secretive does not make it so. If you can find this report/information, please direct our attention to it â I am genuinely curious to know the facts. Even many of the âforthcomingâ producers did not apparently divulge detailed information about their chaptalization usage.
And as for people asking you about blends, alc. levels, and readiness to drink â yeah, sure â those things are important, too. But interest in those aspects does not mean chaptalization information is unimportant or that there is a lack of interest about it. Some of the passages I quoted, above, mention the impact that chaptalization can have on the finished wines, both good and bad; that sounds like something important to me. YMMV.
