Robert Parker's Wine Advocate : The 2015 Cheval Blanc represents the entire vineyard this year, since there is no Le Petit Cheval (two plots that did not meet requirements were not included in any blend). [...] Matured in 100% new oak, it has a very complex bouquet, subtle and tightly wound, very precise with dark berry fruit, hints of graphite, minerals and a hint of black pepper, perhaps a little spicier than recent vintages. The palate is medium-bodied with extraordinarily fine tannin.
Beautifully balanced, perfectly controlled, this Cheval Blanc gently builds in the mouth, but remains strict and precise. The Cabernet Franc here is very expressive (though apparently the Merlot was showier prior to malolactic). This is an intellectual Cheval Blanc, thoroughly enjoyable, but it will need 10-12 years to really show its pedigree. A profound wine in the making, it will rank with the great wines of the past.
Blend : 53% Merlot and 47% Cabernet Franc.
