The taste sensations of coffee: sour - bitter - sweet

The taste sensations of coffee are different and we can divide them into:

Acidic taste sensation: it is due to the chlorogenic acids and their presence is influenced by the roasting of the coffee, which, the more and push, the more it reduces the sensation.

Bitter taste sensation: it is felt at the bottom of the tongue and arises from compounds that are formed from the sugars during roasting. The bitter sensation is normally present in coffee and is considered a positive aspect of the product, as long as it does not exceed certain levels of "tolerance." Bear in mind that the bitter sensation is accentuated by acidity and that this sensation is more present in Robusta coffees

Sweet taste sensation: it is mainly due to the residual presence of sugars in the roasted coffee. The more roasting given to the coffee, the less sweet sensation present because as the heat increases, the carbohydrates present decompose.
