This time, we’ll be talking about sweetness and bitterness. It is impossible to introduce these characteristics without mentioning the two main varieties of coffee that present particular differences in this area: Arabica and Robusta.
Coffee made with Arabica beans has acidic but not bitter notes, contains more sugars and less caffeine, and therefore has a sweeter, more delicate flavour. In coffee made with Robusta beans, the aromatic notes are less prominent, whereas the flavour of caffeine is stronger, resulting in a stronger, more bitter, fuller-bodied result.
The sweetness of coffee
Sweetness has to do with the sense of taste and obviously concerns the sweet, smooth sensation we experience when tasting a coffee. As we have seen above, Arabica is very sweet due to its higher sugar content whereas Robusta is less so.
The perception of sweetness in a coffee is often associated with the perception of a fruity taste on the palate and on the tip of the tongue. Professional tasters and roasting houses like ours refer to the sweetness of the coffee when we want to describe the intensity of the quantities of sugars perceived during the tasting experience.
Sweetness is one of the most important properties that makes a coffee a quality product, and to respect it, the roasting phase is key. A roasting process that is too strong and aggressive will almost completely cancel this property. Our roasting technique is always medium because our objective is to maintain a balance between the levels of sweetness, bitterness, and acidity.
The bitterness of coffee
For all foods, the stronger the roasting process, the more bitter the end result, and coffee beans are no exception. The longer and hotter the roasting process, the darker the beans and the bitterer the coffee blend made with them will be.
For each type of bean we use a medium roasting process that limits the bitter taste, on the contrary releasing the entire range of aromatic notes typical of the coffee variety. If the coffee is not excessively bitter, the acidic note for which this beverage is so well-known is also released.
An espresso has a round, well-balanced flavour when, starting from the dedicated roasting process used on the beans, it succeeds in maintaining an excellent balance of acidity, sweetness, and bitterness. And in fact, this is the same balance that we consistently strive to preserve intact in each of our blends, recognisable in all our recipes.
