Why The Rainy Season Could Damage The Coffee Harvest?

Several years ago and recently, Brazil and also countries in Latin America and Africa which are areas of coffee planting had suffered considerable losses ranging from the process of planting to harvest. In some reports, Brazil and Ethiopia were among the most severe of all because their losses were close to 80% of total regular income. Global warming and climate change are increasingly becoming - so make coffee trees that they plant become more susceptible to pests, coffee cherry ripening process also becomes not maximal so also affect the harvest.

And a similar case was also happened to coffee farmers who are in the highlands of Gayo, Sumatra. Last November, several members of Coop Coffees traveled to various coffee plantations in the Gayo area of ​​Aceh. Their journey found that Gayo coffee harvested around the area was seriously damaged by the lack of rainfall during the period of January to September 2016, this year.

Low rainfall, prolonged drought, rising temperatures slightly higher make the coffee cherries become very slow to mature. As a result, there are quite a few empty coffee cherries on coffee trees. Meanwhile, when the rainy season finally arrived at the end of September, it coincided with a period of drying coffee beans where farmers need bright sunlight for days to ensure a stable quality of coffee.

The rainy season does play an important role in producing coffee cherries. But if the rainy season comes at the same time during the harvest season, then it also means a threat to the mature coffee cherries. High rainfall can make the coffee cherries fall to the ground, which if left in a long enough period will make the cherry (the fall) was fermented.

Another risk that can also happen is the coffee cherries remain in the tree trunks but experienced cracking process-the surface of the fruit experiencing a "crack" is quite significant. This condition is happening in El Salvador today. Cracking occurs because too much water is absorbed too quickly to make the cells in the blooming cherry blossom skin 'expanding excessively'. As a result, coffee cherry skin becomes broken.

In the end, this incomplete coffee cherry will produce a low cupping score (because of the sweetness of many coffee cherries seeping out) in addition to cherry weight that also decreases and is lighter. In other words, because of cracking, coffee cherries can lose a considerable amount of fruit flesh which generally affects the sweetness factor of the coffee to be processed later.

This excessive rainfall problem is not only detrimental to those working in the coffee farming sector, but also in the processing department. For those who concentrate on packaging and shipping, rain can lead to a more serious impact. If the intensity of the rain is so great, then the coffee cherries need to be dried many times and often will require further processing. All this will certainly cause problems on the quality of coffee produced later.

Like the domino effect, the turmoil of the harvest in El Salvador is currently at risk for the "timeline" of the next harvest. Since coffee flowers are already blooming, it is likely that they will start the next crop in August 2017, a few months ahead of time.
