It's funny...I came on here a while back recommending a $20 bottle...and then I bought a few more, and the wine changed for me...which means it was probably me, not the wine...and I was probably in a good place when I tasted it first.
Then again, there are some wines that are consistently good no matter what mood I'm in. For example...
I opened a Nickel & Nickel Cabernet for Easter dinner for the family. My son said, "That's the best wine I've ever tasted." I said, "Me too."
