In Brazil, a cold snap delivers a blow to coffee growing

An unusual cold snap, with temperatures dropping to freezing levels in a matter of minutes, delivered a blow to the heart of Brazil's coffee belt, damaging trees and harming prospects for next year's crop, farmers said.

Agricultural products across the western hemisphere have been beset by unusually bad weather — be it floods or extreme drought — all season. Brazil is the world's largest coffee producer, as its climate is most conducive for production of the beans. Coffee prices surged nearly 14% in response to the frosts, nearing four-and-a-half year highs.

The sudden frost happened Tuesday morning. Farmers, brokers and analysts were assessing their crops last week after reports that the cold snap was much stronger than expected.

"I've never seen something like that. We knew it would be cold, we were monitoring, but temperatures suddenly went several degrees down when it was already early morning," said Mario Alvarenga, a coffee producer with two farms in the southern part of Minas Gerais, Brazil's largest producing state.

Farmers shared pictures of their crops, where large black areas were visible in places where they should see dark green spots marking coffee trees.

"I will probably have to take out some 80,000 trees, they are burned all the way to the bottom," said Airton Gonçalves, who farms 100 hectares of coffee in Patrocinio, in the Cerrado region of Minas Gerais.

"I was going to the farm yesterday and a sensor in the truck started to alert me about ice in the road. I thought the system had gone crazy. But when I got to the farm, it was covered in ice, the roofs, the crops."

Frost hit from the south to the central parts of Minas Gerais.

Joel de Souza Borges, a coffee broker in Patrocinio, believes that around 50% of farms in the Cerrado region were hit. He said this year's production will not be harmed, since most areas were already harvested, but production in 2022 is a question mark.
