On the subject of Ile, rather than 2014, who has dabbled in Dubreuil-Fontaine. I brought a bottle to a 2010 off-line a few years ago, which was perfectly good, if a bit lighter in style than Briaille's (or Bize's) wines.
D-F's website recommends surprisingly short cellaring times for some of its 1ers - 2 to 5 years for its Pommard Epenots; 5-8 for its Corton Clos de Roi.
My note from back then:
this wine showed very well, with pleasant, generous aromatics and surprisingly accessible fruit on the palate, tending towards the dark end of the fruit spectrum - cherries, plums, etc. A babe, but worth opening one now if you have several. The house style contrasts with that of Chandon de Briailles, which ferments with stems, producing a tauter, more structured and elegant Ile, at least in youth.
