WORSE-TAST­ING COF­FEE (AND WINE, AND BEER!)

BBC Earth (Asia) - - Science -

Changes in weather pat­terns will leave less land suit­able for cof­fee-farm­ing. Half of Ethiopia’s cof­fee-grow­ing re­gions could be lost, and those ar­eas most suited to cof­fee pro­duc­tion will be the hard­est hit, ac­cord­ing to one 2017 study. The chang­ing cli­mate will af­fect other drinks, too. Some craft beers need cool overnight tem­per­a­tures to draw in wild yeasts from the air, while in vine­yards, tem­per­a­ture de­ter­mines when the grape har­vest starts. So far, hot­ter sum­mers have made for ear­lier har­vests and bet­ter-tast­ing wines, but ex­perts think we’ll soon reach a point where the heat, cou­pled with in­creas­ing rain­fall, will re­duce qual­ity.
