Americans are full of shit. I'll show you.
First, here's the Gallup preference chart
Except it's not. The above is what Americans say when pollsters ask them what they like. Below is what they actually buy.

This is not to say the Gallup poll doesn't matter. It captures a snapshot of people's opinion of wine, which is generally positive. But as a country, we lie to pollsters, especially when they ask about what we eat and drink.
Example: We tell McDonald's that we want salads, and then we don't buy them. We say we're eating healthier as a nation, but in fact we're eating bacon-filled tater tots.
I could get more into the Gallup data, particularly the fact that women report themselves as much bigger fans of wine than men. Maybe that's true, and it's worth knowing for people trying to sell wine.
But for this post, let's stick to the facts. Americans may say we prefer wine, but we're still buying 10 times as much beer.
