In 2016, Mother Nature and Rheinhessen’s top growers seem to have made the same request of one another: “Cool it!” Happily, both complied. Without question, Rheinhessen growers have experienced two outstanding vintages in 2015 and 2016, but the latter boasts a surplus of wines that display the imponderable interplay of balance, elegance and charm, which to my palate give them a slight qualitative edge and an at least equal claim on cellar space.
