I love wine. Unfortunately, wine no longer loves me—the long headache isn’t worth the short buzz. But according to wine expert Olivier Magny, it’s not the wine itself that’s the problem, it’s the type of wine I’m drinking. Cheap wine. American wine. Sulfites in wine. Olivier, who has taught the art of sommelier-ing to more than 100,000 students at his Paris-based O Chateau, has a problem with sulfites and wine. “Wine should never give you a headache,” he told me. “Good wine—which in my book doesn’t mean expensive but does mean well made—is guaranteed headache-free.”
