Such an appreciation may just enhance your sensory experience, enriching every sip you take. Remember, the beauty of coffee is not limited to its aroma and flavor; it also resides in the incredible story of its origin—from plant to cup.
What do coffee plants look like in their natural environment?
Coffee plants are typically bushy, evergreen shrubs that can grow to heights of 6 to 15 feet, depending on the variety and conditions. They feature glossy dark green leaves and, when in bloom, produce small white flowers that emit a sweet fragrance. The overall appearance of a coffee plant can be quite striking, especially when covered in clusters of ripe coffee cherries.
As they mature, coffee plants also exhibit a dense canopy, which helps to protect the coffee cherries from harsh sunlight. The understory foliage allows them to thrive in their natural habitat, often found in shaded areas. This foliage not only contributes to the aesthetic beauty of coffee farms but also creates a rich environment for biodiversity.
What are coffee beans before they are processed?
Before they turn into the coffee beans we commonly recognize, they begin as seeds nestled inside the coffee cherries. These cherries, which can range in color from green to yellow to red as they ripen, contain two seeds (or beans) within each. The outer skin of the cherry, along with the pulpy fruit, provides natural protection for these seeds during their growth on the plant.
After harvesting, the coffee cherries undergo a process that includes removing the outer fruit and parchment layers. This extraction reveals the green coffee beans, which are then dried, sorted, and roasted to achieve the flavor profiles we love. During this journey from plant to cup, the beans lose their initial fruitiness and develop complex characteristics through roasting.
How do the cherries change color as they mature?
Coffee cherries undergo a colorful transformation as they ripen, starting from green to yellow, then red, with some varieties even turning to a deep purple or black when fully ripe.
