Roasting coffee. How and why?
The coffee roasting process is the phase in which the beans are transformed and made suitable for consumption. Each coffee has its own characteristics, making each roast unique. The roasting process is an art that involves technique, knowledge and experience, and requires precision on the part of the roaster operating the machine, so that everything happens at the right time.
How is it roasted?
Specialty coffee is usually roasted in small quantities by an experienced roaster and it is during roasting that the best characteristics of the coffee are brought out. Before starting to roast, it is important to know the weight of the green beans, the percentage of moisture and the density of the beans, all of which are necessary for the roasting plan. Coffee is usually roasted using gas (there is also an electric method) and as it is roasted, the properties of the beans begin to develop.
The length of time for each roast varies between approximately seven and fifteen minutes, depending on the degree of roasting that the roaster seeks to obtain.
Why do we roast coffee?
Green coffee beans do not look or taste good, which is two of the reasons why it is important to go through the roasting process. When we roast coffee, the sugars contained in the beans caramelize, giving us the brownish color we are familiar with.
Commercial brand coffees are over-roasted with the intention of hiding and camouflaging defects due to their poor quality. This is why sugar has always been a companion in many people's cups of coffee. On the other hand, specialty coffee has a variety of roasting profiles and is rarely over-roasted, because the aim is not to hide or camouflage anything, on the contrary, the aim is to highlight its qualities and aromas.
Answering the question, coffee is roasted so that we can enjoy the wonderful drink that delights us every day.
