​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.

Memory in simple words, simplifies our life and balances our central nervous system.
