Wine bars are awesome. And the Yadkin Valley wine bar in the Charlotte airport is a great idea. I must have gotten lucky the day I went through there because the "guy" everyone else was complaining about wasn't there. Instead, there was the cutest 20-something girl serving up the wines and making recommendations.
She was knowledgeable, quick, and professional. I enjoyed listening to her insight into the local industry and even though she was busy, she readily recommended some selections based on my palate. I tried two flights of tasting, the Rieslings and the reserve reds. There was nothing to complain about.
The Westbend 2007 Riesling was actually pretty decent for not being a late harvest vintage. I also really liked the 2004 Shelton Port. The best of all was a cabernet blend that for the life of me I forgot to look at the label and can't remember what it was. It was a blend of a handful of things and it was smooth, bold, and with the faintest hint of pepper and coffee. Apparently the Yadkin Valley had a bit of a rough season in 2007, but you couldn't tell it by the wines. A few were a little weak for my taste, but a few of them did stand out as solid daily table wines. And I still can't get that Salem Fork Snow Hill White off my mind. It's light as hell but it grows on you.
If you've got the time and enjoy wines, stop in the Yadkin Valley wine bar... but do a tasting flight instead of ordering straight off the menu. You might just find something interesting.
