Drank this over two nights. The first night it was closed and took over three hours to open up even a little. You can sense the fruit, but it is deeply buried underneath the tannins. The tastings notes I have read suggest it should have been more open, but for me it took quite awhile for the fruit to mix it up with the tannins.
Second night, great transformation. The fruit came right to the surface. The tannins dropped into the background and were sweeter and resolved better into a long finish. A keeper, but probably not going to be at its best for five years or more.
I got it for a good price as Safeway has a lot of wine on deals right now. It was around $30, which is actually reasonable for finer California Cabs. Worth it to buy and put away for awhile.
Arrowood has a nice website and lovely winery.
