How is Coffee Made: The Journey of Coffee from Seeds to Cup
Taking out coffee beans, grinding the coffee beans and brewing for a cup of coffee, the whole process to make a good coffee only takes 10 minutes or so. But do you ever wonder how is coffee made? Do you have any idea on how long the journey of coffee from seeds to cup is?
Coffee seed is actually an unroasted green coffee bean. After seeding, it takes about 75 days to germinate into a plant. Then, it takes 3-4 years to producing fruit. The coffee is mainly planted. Meanwhile, coffee plants grow within a defined area between the tropics of Cancer and Capricorn, termed the bean belt or coffee belt.
Harvesting the Cherries
Once the coffee fruit, called coffee cherry, turns a bright and deep red, then it is ready to be harvested. In some countries, the picking process is done by machines, like Brazil. However, the majority of coffee in the world is still picked by hand. After picking the cherries from the tree, it is necessary to separate the unripe from the ripe ones.
Processing the Cherries
In case the picked cherries spoil, processing immediately is important. There are two ways to process the coffee cherries: dry processing and wet processing.
Dry Processing: This is an age-old method. Simply spread out the cherries on a concrete or brick to dry in the sun.
Wet Processing: This method removes the pulp and skin from the coffee cherry through a depulper. Then, the ripe cherries and unripe ones will be separated through water channels. After that, the beans are transported to large, water-filled fermentation tanks for 12-48 hours to remove the slick layer attached to the parchment. When completed, the coffee beans are ready to be sun-dried.
Milling the Beans
After dry processing or wet processing, coffee beans must get milled to remove the parchment layer or the entire husk. This needs hulling machinery help. At this point, the beans will still have their silver skin and need to be polished. The coffee beans are then graded and sorted. The small-sized or blemished beans might be rejected during this process.
Exporting the Beans
The milled beans, also known as green coffee, are then ready to export worldwide. There are loaded onto ships in either jute or sisal bags.
Tasting and Grading the Beans
The green beans will be going through test for quality and taste. This process is also known as cupping. The tasters, namely the cupper, will evaluate the beans based on the quality of their appearance, aroma and color.
Roasting the Beans
Roasting transforms green beans into the aromatic brown beans that we bought in cafés. The roasting profiles like temperature or roasting method may differ based on coffee’s variety, processing method and desired characteristics. Some people just like home roasting for enjoying the best flavor of the coffee beans. Generally, the first 30 or 45 days of roasted coffee tastes best.
Grinding the Beans
Then you’re nearly ready to drink your coffee. Grind your roasted coffee beans to coarseness for brewing. You can grind the beans with either electric coffee grinder or manual coffee grinder.
