Rose wines--especially those from France--are probably the best and easiest overall choices for the 'right wine' to accompany Thanksgiving dinner.
Rose wines are made from red grapes, not a blend of red and white, contrary to popular belief. It is often a blend of grapes, but may be limited to one. During the wine making process they (the grapes)are left for a little while with the skins on, making the wines lighter in color than a full-on red. They may vary in hue from peachy pink, to deep pinkish, purply red.
The process for making red wine lets the juice sit in contact with the grape skin. Consequently, the longer the skins have contact with the juice, the more color will be extracted.
Regarding Thanksgiving dinner, roses are a good choice if you are torn between a red or white as roses exhibit characteristics of both. They show white wine's crispness and red wine's fruit as well.
Grenache is generally rose's main grape and is best served lightly chilled. Recommended: a Tavel--Chateau D Aqueria from the Rhone, or a Rose d'Anjou from the Loire, both French.
