One of the most fascinating aspects of Nebbiolo is its ability to express an extraordinary amount of information with regards to vintage, site, microclimate, terrain and a host of other variables. That seemed to be the overwhelming takeaway from my tastings of the 2006 Barolos. To gain as much perspective as possible, I tasted the 2006 Barolos next to vintages 2005, 2007, 2008 and 2009 (where the wines were through malo) at a number of estates including Giacomo Conterno, Altare, Clerico, Brovia, Conterno-Fantino, Bartolo Mascarello, E. Pira, Sandrone, Scavino, Vietti, Roberto Voerzio and others; while at a handful of addresses time constraints allowed for a comparison with just 2005 and/or 2007.
