Frosty Night in Brazil
Brazil Coffee: Assessing Damage and More Cold on the Way
- Several points to consider:
- There are two type of frost. One caused by temperatures at 2C or below and the other caused by a temperature range of 2C to 5 C with strong winds, which is called a black frost.
- It seems that depending on the location, either of these conditions was present, which is why leading up to the weather event, many were not worried as the forecast temperatures were not low enough to cause damage.
- The day of the frost leaves show brown tinging around edges and turn a lighter color first. Then as the day progresses, the leaves start to dry out and die.
- It can take several days for the full extent of damage to be determined depending on whether the plant itself was harmed or just the leaves and buds that had started to emerge already.
- This frost will be yet another strike against 2022/23 production and with young trees likely hurt, reduces potential for 2023/24 as well, all else being equal.
- The 2021/22 crop is largely harvested. The frost will not impact any quantity of cherry remaining on the trees, but may hurt the quality of this coffee.
