I've been drinking more Texas wine lately, so this year I'm serving Texas wine at Thanksgiving. I like to offer guests a red and a white, so I've chosen McPherson Viognier and Becker Claret.
Here are some previous posts that can help you decide what to drink with your Thanksgiving meal this year:
-- Riesling, whether sweet or dry, is a classic choice. If you go this route, you might want to consult the Riesling Cheat Sheet or "My continuing quest for cheap, dry Riesling."
-- Reds or rosés from the Southern Rhone Valley in France would also be a good choice.
-- If you're interested in serving sparkling wine, check out "The 2-Minute Guide to Bubbles."
-- See last year's recommendations for reds, whites, and sparkling wines at "Ideas for Thanksgiving."
-- I recently posted the Botrytis Cheat Sheet, a primer on the fungus that contributes to many amazing dessert wines. Any of these botrytis-affected wines would pair well with your pumpkin pie.
