The typical Italian espresso is the result of a combination of different types of coffee, almost never from a single source. Precisely for this reason, we often speak of a “blend“, composed of various types in order to encompass, in a single solution, different organoleptic characteristics and to satisfy the most varied tastes.
Thanks to the blends, it is difficult to taste a coffee that is only Mexican, only Brazilian or only Indian, nor is it necessary to request it specifically. All you have to do is refer to a single blend that includes them all and you’re done!
Coffee is a natural product, so its quantity varies from year to year, depending on the harvest. The use of blends makes it possible to keep its availability constant without altering its quality. On the contrary: the more “origins” there are, the better the drink will be. Having more options available, the roaster always has the possibility to rebalance the blend whenever the need arises, without having to resort to unexpected changes that could affect the flavour, aroma and taste.
Each blend is composed of coffees of different origins, each with its own aromas, its balance between sweet and bitter, its body. By blending them together they blend, balance and optimise, creating something new, unique and magical. This is why blending is defined as a true art: knowing how to combine different characteristics, taking the best sides and smoothing out the strongest ones, is a technique that certainly not everyone is able to do perfectly.
The first step towards a good quality blend is to choose a carefully selected raw coffee, but this is not enough: the composition, blending, roasting and preparation must be carried out correctly in order to obtain an excellent result. For this, it is necessary that the operation is carried out by expert and knowledgeable hands, able to mix the different aromas of the various types of coffee chosen in a constant balance.
In the face of technological innovations, even today the best tool for evaluation is man: the human sense organs can never be supplanted by a machine, nor can experience and training. An expert, therefore, evaluates:
