​Unlike other species in the animal kingdom, humans are predominantly visual: around 90% of the information our brain processes is visual. This hinders the development of short- and long-term memory linked to the other four senses. For this reason, developing gustatory memory, for example, requires training, and not everyone has the same capacity to do so, due to differences in sensory receptors. Each person's ability to perceive and register sensory details is unique and is influenced by both physiology and the culture and environment in which we live.

​Umami is described as the fifth flavour, along with sweet, sour, salty and bitter. It is a savoury flavour that can be found in foods such as tomatoes, mushrooms, soy sauce, and aged cheeses, and is attributed to the presence of glutamate in these foods. Glutamate is a neurotransmitter, responsible for sending messages between neurons and the brain. All foods, including coffee, contain some amount of glutamate. Tomatoes, cheese and mushrooms contain high amounts of glutamate. However, in coffee, it is unlikely that this flavour is derived from free glutamates, as there are very few free glutamates present in green coffee. Therefore, it is more likely that the umami flavour that we sometimes find in certain lots is attributed to other compounds and substances present in coffee.

​One of the smallest countries in Africa, Burundi is landlocked and has an equatorial climate. Burundi is part of the Albertine Rift, the western extension of the East African Rift. This is important because the soils of the Rift Valley are volcanic and very fertile. Its cultivation areas are characterized by producing a cup with intense phosphoric acidity, full body with some fruity notes and complex flavour.

1. What is memory?

Memory is the process through which we obtain, store, retain and access information. Human beings are capable of perceiving reality through experiences, which we classify and store. This process allow us to survive, cause if we were not able to access past experiences to decode the new ones, we would be living each day in a constant chaotic state of wonder, terror, happiness or stress. Memory in simple words, simplifies our life and balances our central nervous system.

​The taste of people has been built with the course of history, and some events have strongly contributed to shape it. Like for example, the arrival in Europe of sugar or spices during the medieval era. Throughout history some flavors appears and others, like bitterness, go out of fashion.
