OK it happens every year, a flood of people think there must be one perfect wine to go with "Thanksgiving dinner". Never mind that Thanskgiving dinner is 100 different things to 100 different people. Some people have very bland turkey and mashed potatoes. Some have very sweet candied yams and sweet cranberry. Others go for the spicy flavors. No one wine would be "perfect" for all these different situations!
Then we have the different issue. If you hate buttery Chardonnays, then it doesn't matter if some wine expert somewhere feels a buttery Chardonnay is perfect with turkey meat. You're going to hate it. You might do far better with a smooth merlot. If you favor a spicy, pepper gravy and heavy duty side dishes, then a Shiraz as a wine might be perfecto.
So I want to say that no wine is ever the perfect wine

It all depends on your dishes you're making, and your taste buds. A wine I absolutely adore with Thanksgiving, you might find far too mild, or too sweet, or too tart.
What wine are YOU having for Thanksgiving, and what food items are you serving it with?
