(Reuters) - Thanksgiving, the U.S. holiday that anyone who likes to eat loves to celebrate, is just a week away and experts agree there is not one perfect wine to accompany the feast, but many. "No other holiday celebrates the gift of wine like Thanksgiving," said Natalie MacLean, author of the new book, "Unquenchable: A Tipsy Quest for the World's Best Bargain Wines." "Wine is a taste of the harvest along with all the delicious dishes on the table," MacLean said, conceding that sometimes choosing a bottle can feel like a thankless task.
