Disgorged in May 2020 with two grams per liter dosage, the 2012 Extra-Brut Blanc de Blancs Grand Cru is fabulous, bursting from the glass with notes of smoky pear, white flowers, walnuts and baking spices. Derived predominantly from holdings in Avize, it's full-bodied, layered and immensely concentrated, with a tightly wound, structured core and racy acid spine that mark it out as emphatically built for the long haul. Deep and vinous, I suspect that it will surpass the 2008 rendition at maturity.
