Before you pop a cork to celebrate North America saving the day, note that phylloxera arrived in Europe via New World imports in the first place. Oops.
14. Phylloxera is bad for wine, but wine is good for us, right? Not so fast. Headlines proclaiming a glass of red wine is as good for you as an hour at the gym were based on a 2012 study observing the effects of just one compound in red wine — resveratrol — on rats, not humans.
15. In fact, a 2013 study of men aged 60 and up found resveratrol seemed to diminish many of exercise’s positive effects. Participants working out and taking resveratrol supplements saw fewer improvements in blood pressure and oxygen uptake than those just working out.
16. While red wine gets most of the study spotlight, an analysis of more than 38,000 health professionals found it was no better than beer or spirits at reducing heart attack risk in moderate consumption.
17. Whether it’s good for us or not, wine may be in for rough times. In February, researchers sequencing the genomes of commercial yeast, used in most wine production, announced that inbreeding has created low genetic diversity. That makes it harder for a species to adapt to novel pathogens.
18. Climate change also poses a threat to wine. A 2006 study estimated that rising temperatures would shrink top-quality wine-growing regions in the U.S. up to 81 percent by 2100.
19. Even if vineyards relocate northward in search of cooler climes, increased precipitation in areas like the Pacific Northwest could make crops more susceptible to fungus and rot.
20. It’s not all bad news, though. Critics of the more pessimistic models note that there’s no accounting for adaptation. We’ve been making wine for thousands of years, adjusting to different terrains and climates. Our descendants will almost certainly be enjoying vino for millennia to come. And we’ll drink to that.
