The pick of the cherries of coffee plants will depend on the country of production.
Coffee is harvested during specific "maturation" periods which are delayed by weather factors. There are three main harvesting periods for coffee beans: early, mid-, and late-season harvests.
Although, there are four major aspects to consider when harvesting coffee beans - The altitude of the region, region rainfall patterns, region climate, and region soil composition. For example, if a country is on a northern mountain slope with a lot of rain it will need a shorter picking season because more rain impacts the quality and flavour of the beans. With that said, some regions have an ideal time to harvest - which means they either pick at night or delay until that period has passed. Soil also plays a factor as certain soils tend to produce better crops than others as well as provide better yields for certain bean varietals too.
