A persistent El Niño and extreme weather are disrupting major coffee-producing
regions, posing a material test for the global coffee supply chain. Brazil's
southeast has experienced abnormal rainfall and heat; farmers and industry warn
the 2027 harvest will face both lower volumes and downgraded quality. A local
coffee cooperative CEO, Bernardo, says markets are already on alert and 2027
national output forecasts have been revised down, with overall production
expected below prior estimates.
