Opening in the glass with notes of white flowers, pear, beeswax, mandarin orange and iodine, framed by a light touch of youthful reduction, the 2018 Chassagne-Montrachet 1er Cru Grandes Ruchottes is medium to full-bodied, layered and tightly wound, with lively acids and good depth at the core. Bottled under Diam, this is quite reserved, even in the inherently giving 2018 vintage, and it will reward a bit of bottle age.
