Hello Kannan,
Look for another source. The only regions in Brasil with arabica more or less spared are the south of Esprito Santo, witch has little arabica and the regio de Mata.
But also over there the plants have suffered and production will be down.

21 crop will be near 60 million bags. 22 crop even lower.

Nobody discusses a complete loss of at least 180.000 hectares. Do this number times a low 25 bags a hectare than you already have 4,5 million bags.
Now you have to add losses for drought and as a bonus the losses caused by loosing the fruits.


(Complete loss means cutting down at the bottom, heavy pruning or re-planting)
