Full-bodied, with solid tannins and long finish. Best after 2007.
Reg $49.99.Sale $34.99 (2,165 cases made.)

WS rated 2001 vintage for Brunello 98 points.

Why is Poggio rated 91 points, and vintage for Brunello 98 points?
Is this two different rating systems; one for the wine itself and one for
the year (vintage)?
Thanks.
