Wine Tasting

[oldworld]

Try to rent glasses, or get the distributer to provide them. You'll need quite a few. You don't necessarily need a new glass for each wine, but you'll need a fresh glass for every time you have a strong flavor in a wine and don't want it to linger into the next sample.
For example: following Californiagirl's suggestion of Andrea Immer's tasting, you could taste out the champagne, riesling (new glass or rinse) chardonnay (NGoR), Sauvignon Blanc -then (NGoR)Pinot Noir, (NGoR)Merlot, (NGoR) Zin or Cabernet Sauvignon (whichever's bigger, with a NGoR in between).
When you're new to tasting wine, it's important to start with the fresh flavor of each wine. If you can't do multiple glasses (I know I wouldn't want to wash them!), buy one large bottle of a mild white such as trebbiano, and pass it around for people to rinse their glasses with it between wines. It's better than water, which has more chemicals to affect flavor.
I hope you have a great time tasting!
P.S. I was born and raised in Texas, and I'm pretty excited about the Hill Country as a wine region.
P.P.S. I always end tastings with Moscato, it's incredibly refreshing and low in alcohol too.
