Keller's 2015 Riesling Trocken is clear, precise, ripe and fresh. This is an aromatic, limestone-Riesling classic with some lovely flavors of crushed stones. The wine is dry, but round and aromatic, very elegant and finesse-full. This is a charming Riesling that finishes with a pretty long, intense and aromatic aftertaste with a stimulating purity and salinity. A Best Buy and probably the finest VDP Rheinhessen Gutswein of the vintage.
