Did you know? There are records of people drinking coffee as early as 800 A.D.
History of Coffee
Coffee cultivation dates back centuries to old coffee forests on the Ethiopian plateau. According to folklore, goat herder Kaldi tribe initially discovered the treasured beans.
Coffee was grown in Arabia's Yemen region by the fifteenth century. It was well-known in Persia, Egypt, Syria, and Turkey by the sixteenth century. Travellers from Europe to the Near East returned with tales of a peculiar dark, black liquor.
Coffee arrived in Europe in the 17th century and spread to other parts of the continent. There was intense competition to grow coffee outside of Arabia as the beverage's popularity grew.
Steps To Manufacture Coffee
Manufacturing coffee involves several steps, from selection and harvesting to brewing. Let's discuss some steps involved in coffee manufacturing in detail:
1. Selecting and Harvesting Coffee Beans
The initial stage in coffee production involves choosing and harvesting beans from coffee plants. The purity of coffee beans at this processing stage considerably impacts the final product's flavour and fragrance.
In this part, we will look at how coffee beans are made, different types of coffee beans, and distinct harvesting techniques.

How is Coffee Produced?
Coffee seeds, a member of the Rubiaceae family, are extracted to make coffee. The coffee fruit, also known as cherry, contains seeds, which go through processing to make the finished product.
Coffee production comprises multiple processes, notably coffee bean selection and harvesting, bean processing, roasting, and brewing.
Coffee Bean Types
Arabica and Robusta are the two primary types of coffee beans. Arabica beans are of superior quality and are used to make speciality coffees, while Robusta beans are used to prepare instant coffee and mixes.
Arabica is an exceptionally fragile plant that requires particular circumstances for development, making it more costly to cultivate. On the other hand, the Robusta plant is more resilient and can be nurtured in an expanded variety of surroundings.
Hand-picking and strip-picking are the two preferred ways of harvesting coffee beans. The conventional procedure is hand-picking, which involves choosing just the ripest coffee cherries from the plant, resulting in better-quality beans.
Strip-picking, on the other hand, involves gathering all coffee cherries from the tree simultaneously, regardless of their maturity, which leads to inferior-quality beans.
Aspects Influencing Bean Selection
Several variables influence coffee bean flavour throughout the selection process, including elevation, soil type, precipitation, and temperature. The ideal circumstances for cultivating high-quality coffee beans include high elevation, soils that drain well, and moderate precipitation amounts.
The temperature should be reasonable, with no sharp variations. The maturity of coffee cherries influences bean grade.
Bean Selection for Longevity
Sustainability has also become more significant in coffee bean choice. Sustainable coffee growing practices conserve the environment while ensuring producers' financial success.
Many coffee firms now get coffee beans from environmentally friendly farms supporting fair trade and ethical business practices.
2. Processing Coffee Beans: From Pulp to Green Beans
Processing coffee beans is crucial in coffee-making since it impacts the end product's flavour and smell. In this part, we will look at how coffee beans undergo fermentation from the fruit to the green beans.
We will also look at the numerous processing techniques utilised and how they affect the flavour characteristics of the coffee.
How Are Coffee Beans Made?
Coffee beans are manufactured from coffee fruit seeds. The seeds are collected after the fruit has been obtained, and the coffee processing step begins.
The dry and wet techniques are both basic processing procedures.
- The Dry Method
The sun drys coffee cherries, keeping the fruit undamaged until it can be readily extracted. After that, coffee beans are separated, evaluated, and packaged.
This process is less costly, producing coffee with a sweet, fermented flavour.
- The Wet Method
Before drying the beans, the outer covering of the coffee fruit must be removed using the wet approach. The coffee cherries are then processed in a pulping machine, which separates the outer peel and pulp while keeping a piece of paper intact.
After that, the beans undergo fermentation to eliminate any leftover pulp, are cleaned, and dried. This process produces a clearer, more uniform flavour profile and is favoured for high-quality speciality coffees.
3. Roasting Coffee Beans: Turning Green Beans into Brewable Beans
The act of converting green coffee beans into brewable beans is known as "roasting." It is a crucial step in the coffee roasting procedure that improves its fragrance, flavour, and general quality.
This part will take you through the roasting process, how it affects the taste characteristics of the coffee, and the various roasting levels.
The Roasting Method
Roasting entails heating green coffee beans at elevated temperatures until they become brown and unleash their distinctive scent and flavour.
Roasting duration and temperature may be adjusted to get the ideal roast level.
There are many roasting levels, each with its own flavour and character. Medium roasts provide a more nuanced flavour with undertones of chocolate and nuttiness, while mild roasts have fresh acidity and fruity aromas.
Dark roasts have a strong, smokey flavour with low acidity and a hint of bitterness.
Influence on Flavor Profile
Roasting influences coffee's flavour and character. The degree of roasting can influence the degree of acidity, bitterness, sweetness, and general flavour of the coffee.
The roasting procedure can also affect the coffee's scent, body, and mouthfeel.
4. Grinding and Brewing: The Final Stages of Coffee Manufacturing
The roasted coffee beans are ground and brewed in the final phases of the coffee production procedure to produce a pleasant and flavorful cup of coffee.
In this part, we'll look at how different ways of grinding and brewing coffee affect the flavour and fragrance of the finished product.
Grinding coffee is a critical step in the coffee-making process since it affects the flavour and fragrance of the coffee.
Depending on the brewing process, coffee beans are crushed into tiny bits of varying sizes. The size of the grind influences brewing time and coffee intensity.
One of the most common brewing techniques is drip coffee. This involves hot water running over a layer of ground coffee in a filter composed of paper.
The water drops into a carafe, producing a thick, silky coffee cup.
The French Press
A pressurised pot, often known as a French press, is a traditional brewing method. It includes soaking the coffee grinds in boiling water and pushing the plunger to separate the grounds from the coffee.
French press coffee has strong and powerful flavours with a thick body.
Espresso is a preparation process in which pressurised hot water is forced through coffee beans that have been thoroughly ground.
Espresso has a rich, full-bodied flavour and an extensive flavour profile with a creamy texture.
The latter phases of the coffee production process, grinding and brewing, have an immense impact on the flavour and fragrance of the final product consumed.
Studying the various brewing techniques and how they affect coffee flavours and fragrances may help those interested in coffee understand the complexity of an excellent cup of coffee.
Grind size, brewing period, and water temperature are all key factors in making the ideal cup of coffee.
Coffee production involves selecting and harvesting beans from coffee plants, processing them, roasting them, and brewing them. Arabica and Robusta beans are used for speciality coffees, while Robusta beans are used for instant coffee and mixes.
Hand-picking and strip-picking are two preferred methods of harvesting coffee beans. Bean selection is influenced by elevation, soil type, precipitation, and temperature.
Sustainability is also a factor in the choice of coffee beans. Processing coffee beans is a crucial phase in the coffee-making process.
Coffee beans are roasted to improve the coffee's fragrance, flavour, and quality during roasting.
Different roasting levels have different flavour characteristics, and the degree of roasting can affect the degree of acidity, bitterness, sweetness, and general flavour.
