As someone who grew up in agriculture, I realize how little we know about some of the foods and drinks we consume. For me, it's always fun to find out where foods come from and how they are produced, so I thought I'd share with you some pictures that give you a better idea of how coffee travels from tree to cup.
The coffee tree produces a delicate white flower that has a jasmine or orange-like smell.
Coffee ripens unevenly on the branch and will not ripen after it is picked, so each tree has to be picked multiple times by hand.
A basket of freshly-picked ripe coffee cherries:
Density is an indicator of cherry quality, so machines that use water to sort the cherries are often employed. More precise sorting is also done by hand.
When the coffee has been sorted, the outer pulp of the cherries must be removed. With "water-processed coffee," this is accomplished using a wet mill, a machine that mechanically removes the outer skin and pulp layer. After the coffee is pulped, it is allowed to ferment for a short period of time before being spread out to dry. The coffee is turned frequently until it is dry, and then the outer layer of skin, or parchment, that covers the coffee bean is removed.
Dry-processed coffee is a little different. The whole cherries are allowed to ferment and dry out in the sun before the outer layers are removed. This process is riskier because changes in the weather greatly affect the quality of the coffee, but when it works, dry-processed coffee can have some unique and intense flavors. Arabian Mocha Sanani is one of my favorites that is processed this way.
Once the parchment has been removed, the coffee is sorted for defects, particularly for broken or shriveled beans. This can be done by machine, but for higher-quality coffees, it is often done by hand. The green coffee is stored in burlap (jute) bags and shipped around the world.
Green coffee is stored in warehouses until it is ready to be roasted. A machine like this is used
to turn the coffee into this:
From there, the coffee is ground, brewed and poured. Mmm.
I hope this gives some of you a better idea of where coffee comes from. As you can see, coffee takes quite a trip from the tree to your cup!
