An interesting comparison:

1999 JF Mugnier, Chambolle-Musigny
Hmm, the colour is still good but what’s this aroma? Yes, a little brett… It cleans up just a little in the glass but my hopes of this previously ugly duckling transforming into a swan seem to be dashed. But. What’s this this? A depth of sweet flavour, more generous than I can remember since it was 2 years old – and what a delicious flavour too! Here is extra and something rather complex too. Not a wine for sniffing (an attribute almost as important as the taste) but a wine that I can drink with pleasure. Not something that I’ve said about this wine for a very long time.
Rebuy – No (sorry to say – and maybe I have 1 or 2 more…)

2021 Mélanie & Daniel Buland, Côte de Brouilly Cuvée Mélanie
Ooh – perfume. Some of Daniel’s 21s have a little pyrazine – but there’s none of that here, just the ultra-inviting perfume of flowers and darker red fruit. Vibrant in the mouth, fresh, melting, juicy purity of fruit – still accented with the flowery perfume of the nose. What a simply great wine. If not totally in the flavour department, certainly a step up from the Mugnier as a complete wine – and you can have half a dozen of these for the 1999 Mugnier…
Rebuy – Yes
