Daniel Bouland is one of the top names in Beaujolais, and rightly so I would say. I tasted his 2017 Morgon Corcelette next to Dorli Muhr’s Samt & Seide Blaufrankisch 2017, and while the Austrian is really very good, the gamay is just a more complex wine.
I loved the 2016 vintage of this wine, mostly when it was in its primary state, though (2016 Southern Rhone reds quickly went into a dumb phase in my experience, see also here). The 2019 is good, but not on the same level.
At what age does a mid-range Loire Cabernet Franc tastes the best? A more adequate question is perhaps: if great on release, will such a wine offer that enjoyment later or dumb phases are expected, like in the case of Southern Rhone reds?
