There is just one specially-made 450-liter barrel of the 2015 Batard-Montrachet Grand Cru. The barrel is made with used and new staves so that the effect is 50% new oak (this is the first time I have heard of a winemaker doing this...but it seems entirely logical!). It has a very composed bouquet and yes, it does seem in sync with the percentage of new oak, offering fresh green apple, lime and minerals with time. The palate is very well balanced with crisp acidity, fresh with Granny Smith apples, hints of peach and a dab of toffee just right on the finish. It needs time to knit together - I will be intrigued to re-taste this once in bottle.
