Where’s that bean been? Coffee’s journey from crop to cafe
Origins and Cultivation
Our journey begins in the misty highlands of Ethiopia, where legend has it that a goat herder named Kaldi discovered the energizing effects of coffee beans after observing his goats frolicking with unusual vigor upon consuming them. From these ancient origins, coffee cultivation spread across the Arabian Peninsula, eventually reaching Yemen in the 15th century.
In these mountainous regions, coffee thrives in well-drained soils and moderate climates, requiring ample rainfall and temperatures not too hot nor too cold. Cultivating coffee is labor-intensive work, often carried out by smallholder farmers who carefully tend to the plants, pruning them, fertilizing the soil, and protecting them from pests and diseases.
Harvesting and Processing
As the coffee cherries ripen on the trees, skilled pickers meticulously hand-select the ripest ones, ensuring only the finest beans are harvested. The two primary methods of harvesting are selective picking, where only the ripe cherries are harvested, and strip picking, where all the cherries are harvested at once.
Once harvested, the coffee cherries undergo processing to extract the beans within. There are several methods of processing, each imparting unique flavors to the beans. In the washed process, the cherries are pulped to remove the outer skin, then fermented to loosen the mucilage before being washed and dried. In the natural process, the cherries are dried whole, allowing the beans to absorb flavors from the fruit.
Transportation and Trade
With the beans extracted and processed, they embark on a journey across oceans and continents to reach consumers around the world. In the early days of coffee trade, beans were transported by camel caravan from Yemen to the port city of Mocha, where they were loaded onto ships bound for Europe.
Today, coffee is a global commodity traded on the international market. From coffee-growing regions in Latin America, Africa, and Asia, beans are shipped to major trading hubs where they are bought and sold by importers and exporters. The journey from farm to port is fraught with challenges, from poor infrastructure to volatile weather, but the allure of coffee’s rich flavors and stimulating effects drives the trade forward.
Roasting and Blending
Upon reaching their destination, coffee beans undergo the transformative process of roasting, where they are heated to temperatures exceeding 400°F to develop their characteristic flavors and aromas. Roasting is both an art and a science, requiring skill and precision to unlock the full potential of the beans.
Roasters carefully monitor the roasting process, adjusting temperature and airflow to achieve the desired roast profile—whether it’s a light roast with bright acidity and floral notes or a dark roast with bold flavors and a smoky finish. Some roasters specialize in single-origin coffees, highlighting the unique characteristics of beans from specific regions, while others create blends, combining beans from different origins to achieve a balanced and complex flavor profile.
Brewing and Enjoyment
Finally, our journey culminates in the bustling atmosphere of a café, where baristas expertly brew coffee to perfection. From espresso machines to pour-over drippers, there are countless methods of brewing coffee, each yielding a distinct flavor and texture.
Whether enjoyed black or with milk, hot or cold, coffee is a universal beverage beloved by people of all cultures and backgrounds. It’s a morning ritual, a midday pick-me-up, and a social lubricant—all in one humble cup.
As we savor the rich flavors and intoxicating aromas of our coffee, let us pause to appreciate the journey that brought it to our lips. From the mountains of Ethiopia to the bustling streets of our cities, coffee’s journey is a testament to human ingenuity, perseverance, and passion. So the next time you take a sip of your favorite brew, remember the long and fascinating journey of that humble bean—from crop to café.
