James treated us to the 2011 sometime last year. Two things stood out to me: we had some phenomenal brunellos and super Tuscans that evening, but the Siro Pacenti VV was the most balanced of all, although there was a fair bit more residual sugar than I typically liked. Just excellent wines.
The 2013 and 2015 are even more outstanding vintages for Tuscany, and particularly for the Sangiovese grapes. Insane scores on these 2 wines. I suspect we are going to end up drinking this wines far too young but ah well.
