Wine Advocate-Parker : The final wine in this portfolio of amazing single-vineyard expressions is the 2013 Barbaresco Riserva Montestefano. This is the densest and darkest of them all, and I would therefore suggest that the longest drinking window be reserved for this expression. Montestefano is shaped as an amphitheater of vines that locks in the summer heat and sees less wind compared to Montefico. This is a solid and firm wine with deep, dark intensity and solid tannins that form an unyielding backbone. You should hold onto this bottle for at least 5 more years before popping the cork.
