I am a big Grenache fan but his 75% Garnacha (the Spanish name for Grenache) and 25% Tempranillo is rather blah. It is a nice black cherry hue with black berry and plum aromas but the palate is tight, harsh and thin.
With some air it is still unremarkable and worth passing up. This is the second time I bought a Barsao with a "best buy" kind of hype and have found it lacking. Even at the $10 price point it is worth passing up. Raise a glass of something else.
