I am obviously not David and unfortunately I burned my tongue on some soup before trying this wine, so take what I have to say with a grain of salt, but since there is some interest here on the new Four Gates wines and I haven't seen any write-up as yet, I did try the 2010 Petit Verdot last night.
Deep, dark, almost black in the glass. Stylistically a bit of a departure from most Four Gates reds. The biting acidity and firm tannins that you often see are less overt. I do not think that detracts from this wine but I generally prefer the other style. Somewhat reedy on the nose, the palate is dominated by cocoa. Also over the course of an hour there was little change in the profile. I have about half a bottle left so I will try it again tonight and see if it has changed at all.
Also to be fair, I opened it about 5 minutes after it arrived to my house.
