Your first impression of "les Perrières" is that of a typical Corton, as it is so frequently described: austere, slow to mature, tannic. But that impression should be moderated because the wine is apparently multifaceted: frankness, certainly, but also an underlying structure that lines the palate and a finish marked by minerality. There's no heaviness, which facilitates the expression of this complexity. A long ageing period is certainly beneficial.
