Wine quality is notorious for varying from year to year, but what makes for a "good year"? In a paper publishing October 11 in the journal iScience, researchers show that weather plays an important role in determining wine quality. By analyzing 50 years' worth of wine critic scores from the Bordeaux wine region in relation to that year's weather, the researchers showed that higher quality wine is made in years with warmer temperatures, higher winter rainfall, and earlier, shorter growing seasons—conditions that climate change is predicted to make more frequent.
