With over one-third of the population consuming it on a daily basis with different forms, coffee is definitely one of the most popular processed beverages around the world. Not only serving as drinks, but coffee is also often regarded as a culture. Coffee manufacturing is a knowledge-intensive industry. Coffee beans from different regions will reveal different tastes, while the level of caffeine could also be different. When it comes to coffee bean processing, the range of roasts varies from light golden brown all the way to dark. The way of tasting coffee differs between countries, habits, and tools to use.

Coffee production is the method of converting raw fruits of the coffee plants into the finished coffee. There are various ways of processing coffee, which can significantly affect the flavours. In addition, the final format of the coffee products and how people drink their brewed coffee also plays an important role in the taste. A huge increase in demand for high-quality coffee products means that smaller-scale producers can leverage quality and innovation to benefit from this enormous potential.

Production processes for coffee

After harvesting, coffee cherries need to be processed in either dry or wet method to have the fruits, known as mucilage, which cover the beans, removed. When the skin is removed to leave only the mucilage, it is referred to as the pulping process.

The beans are then separated by weights and sizes by rotating drums or screening sieves. After the beans are dried and graded, they are ready for roasting. Sometimes, the different beans are blended to create desired taste. When it comes to the wet process, fermentation of the coffee beans in essential. Therefore, specialised coffee fermentation tanks will need to be used to achieve this.

Since coffee’s characteristic flavour and aroma only develops until beans are roasted, roasting is an essential step in the process. After roasting, coffee beans are usually ground in roll mills. The primary goal of grinding is to produce the most taste in a cup of coffee, while the type of grinding determines how fast the coffee can release its flavours.

Producing instant coffee

Instant coffee is made from roasted and ground coffee. The grounded beans are extracted with hot water to retrieve the aroma and the flavour. The coffee extract can then be dried in two different ways: spray drying or freeze drying. In spray drying, the coffee extract is sprayed into a stream of hot water, it dries fast and becomes fine powder when reaching the bottom. In freeze-drying, the coffee extract is frozen to about – 40°C and cut into granules. The quality of the aroma and flavour are protected by the very low temperature and gentle drying conditions. Finally, the granules of instant coffee can be packed into sachets or glass jars.

Sustainable trend in coffee packaging

Due to the raising awareness on climate change and social responsibility, sustainability in the coffee industry has become vital considerations. From the perspective of coffee packaging, there’s a growing trend of using eco-friendly materials. Environmental impacts are eliminated in different stages within the production line. With coffee pod waste at an all time high, products like biodegradable, dissolvable capsules aim to reduce environmental impact while still offering high quality coffee conveniently at home. Recyclable and biodegradable materials are also widely adopted for coffee bean bags or boxes.

How to pack your beans or coffee powders?

The quality of coffee beans or ground coffee is quickly diminished by oxygen in the air; oxygen breaks down the precious aromas in the coffee, and the flavour becomes flat. To guarantee as far as possible that the flavour of the coffee enjoyed by the consumer is as good as when it left the factory, coffee beans or ground coffee is very often vacuum or soft-vacuum packed, so that no air can get in.
