This is the last wine I tasted in this group of nine from Produttori del Barbaresco. The reason I placed the 2015 Barbaresco Riserva Montestefano last is because it is usually considered to be the most powerful and determined in the flight. However, when you really get down to it, this vintage is more tight, streamlined and ethereal than expected. It is saving the best for later, and indeed, the wine is poised to evolve and open fully many years from now. There is a note of shyness here or restraint. Exactly 16,036 bottles were made, and this Riserva demands patience.
