"Krug leaves other great champagnes in its wake, as it fills the senses to overflowing. A blend of 48% pinot noir, 35% chardonnay and 17% pinot meunier; 12 years on tirage. It has an incredibly complex play between berry fruits and spicy brioche flavours and it's hard to imagine a better structured and balanced wine. *2020 Top 100*"

"As I reported when it was released, Krug's 2006 Brut is clearly one of the vintage's highlights. Offering up aromas of dried fruits, pear, freshly baked bread, caramelized apples, honeycomb and toasted sourdough, it's full-bodied, deep and layered, with superb concentration, racy acids and an impressively tightly wound profile for this demonstrative vintage. I observed last year that this is surprisingly reserved for the vintage, and if anything, that quality is even more in evidence today. While many 2006 Champagnes are likely to be at their best in their demonstrative youth, this is one wine unquestionably built for the long haul."
