Domaine de l’Ecu has a long and honourable history of exploring the difference in their wines from different terroirs/geology, through making quality wines that are eminently ageworthy. Aged Muscadets are a bit of a minority interest, though I do enjoy the occasional one myself.
Having said that, I haven’t had one since the estate was sold some years ago, but it sounds like the current owner is aiming to continue the good work if he is convincing cavistes to stock them.
All I would add - having just had a quick look at their website - is that they also seem to have introduced a whole range of new wines which appear to be aimed at the natural/winebar end of the market. As these seem to be bottled without added sulphur, I’d suggest they be drunk soon. But they still make the traditional cuvées too.
Just considering our own wines for this weekend. Might open this -
No idea about tomorrow though - let’s see…
