From blossom to brew
When we think of coffee, we usually picture a dark, aromatic drink that wakes us up in the morning. But it all begins with something completely different: a colourful, sweet fruit. Let's explore the story of the coffee cherry, the origin of every cup of coffee. With its complex life cycle and influence on the final flavour of your coffee, the coffee cherry adds another layer of appreciation to your coffee break. Get ready to expand your coffee knowledge and deepen your understanding of your favourite drink.
What is a coffee cherry?
The coffee cherry, sometimes confused with a coffee bean, is actually the fruit that surrounds the bean. These fruits grow on the Coffea plant, which includes more than 120 species, but only two, Arabica and Robusta, dominate the global coffee market. Each has unique qualities, and the difference is comparable to choosing between an elegant Cabernet Sauvignon and a robust Merlot.
The flowering process
From the moment the coffee plant's blossoms open, it takes around nine months for the coffee cherries to ripen. During this period, they undergo a fascinating transformation, usually changing from green to yellow, then orange and finally a deep, tempting red. This is why they are often called 'coffee cherries'. At the heart of these 'cherries', there are usually two coffee beans with their flat sides facing one another.
In each fruit, the seeds usually develop with their flat sides together, giving coffee beans their characteristic shape. Sometimes, however, only one seed grows inside the fruit. This produces a bean that is round on both sides, also known as a "peaberry". These rounded beans account for only around 5% of global coffee production, but they have a certain mystique in the coffee world. It is often claimed that they have a more intense flavour and higher quality because the fruit's nutrients go to just one seed rather than being shared between two. Whether this is really true remains a topic of debate among coffee experts, but it certainly makes peaberry beans unique and sought-after among coffee lovers.
There are different harvesting methods. Sometimes all the cherries are picked at once, meaning ripe, unripe and overripe fruit are all harvested. In other cases, particularly with high-quality coffees, the trees are picked several times to ensure that only ripe cherries are collected. This selective picking contributes to coffee quality but is more labour-intensive and therefore more expensive.
Coffee cherries in the kitchen
Although the coffee bean is the star of the show, the fruit itself is also used in various cuisines and drinks. For example, it is dried and used in tea, or ground into flour for baked goods. In some cultures, the cherries are even eaten raw.
Surprising facts about coffee cherries
Here are some interesting facts about coffee cherries that you might not know:
- The Coffea plant is actually a type of evergreen shrub originally from tropical Africa.
- Coffee cherries are rich in antioxidants and are sometimes processed into a health supplement.
- The pulp of the coffee cherry, often discarded during coffee production, can be used as a natural fertiliser.
Connecting the fruit to the brew
The transformation from a ripe coffee cherry to the roasted end product you pour into your cup is a complex journey. Each stage significantly affects the final flavour of the coffee, and the ripeness of the cherry plays a crucial role.
Picking unripe, green coffee cherries can produce a cup of coffee with sharp, sour notes. This is because the sugars in the fruit, which contribute to the coffee's sweetness and body during roasting, have not yet fully developed.
A perfectly ripe coffee cherry, on the other hand, has the potential to produce a balanced, full-bodied, sweet cup of coffee. The fruit has had enough time to develop its sugars, and these natural sugars caramelise during roasting, contributing to the coffee's rich flavour and aroma.
However, excessively ripe or overripe cherries can give coffee an unwanted stale or overripe flavour. Overripe fruit can ferment, leading to unwanted flavour profiles in the finished product.
Selecting cherries at the right ripeness, combined with optimal processing and roasting methods, is therefore crucial to making your cup of coffee both satisfying and delicious. This is an art perfected by coffee farmers and roasters around the world, and one of the reasons a good cup of coffee is so appreciated.
Conclusion
The coffee cherry, changing from vibrant green to tempting red, is the birthplace of our beloved coffee beans and plays a crucial role in the flavour and aroma of our daily brew.
The complexity of the fruit's transformation, from ripening to harvesting, processing and finally roasting, is reflected in the complexity of the flavours we taste in every sip. It is this complexity and variety that makes coffee so intriguing and loved.
From Arabica's elegant, subtle notes to Robusta's powerful, robust flavour, every coffee cherry contributes to the diversity of flavours found in today's coffee market. And that is only the beginning of the story. From rare "peaberry" beans to the surprising culinary uses of the fruit itself, the coffee cherry continues to amaze us.
