Prüm's 2015 Graacher Himmelreich Spätlese is clear, intense and flinty on the nose, very precise but well concentrated; however, it is the most reductive of the Spätlese quartet. Round and piquant, with a stimulating fruit and salinity, this is a very well-defined, crystalline and straight Spätlese of great finesse and elegance. It needs five years or so to unfold all its talents, but it can surely age for 20 or 30 years. - Stephan Reinhardt
