The Merlot is intensely oaky, BUT, with some years, my experience with the 2000 has been really quite exceptional. I recommend patience. That said, I would rather drink a decent right-banker in a second over any WA Merlot.
I didn’t realize this, but you will be happy to hear that 2006 was the last vintage of the Merlot. The fruit is now just used for blending and the table wine.
Pretty much every Quilceda Cab you have ever tasted (except maybe the 1997 Champoux) has had some Merlot. I understand thinking it is too oaky, and in my experience it takes a LOOONG time to integrate. However I am trying to understand your conclusion that this is another reason not to buy Quilceda Cab. To me that is a somewhat disconnected statement.
