There are many factors that go into producing the best coffees, from where beans are grown to their storage and roasting. Specialty coffee roasters are designed to help control the roasting process and to make it more efficient. Years of experience are usually required to possess the technical skills and background knowledge required for perfect roasting. These enable the flavors of great varieties to be released and enhanced.
The crude machines of the past vary greatly from the computerized versions available today but the basic principles are still the same. The bean is taken from its green state and roasted to release the flavors. Drum machines are commonly used and these work by rotating and causing the beans to tumble around with gas or electricity providing the heat source. Hot air machines are also used and beans are roasted on a currant of hot air.
The modern machines vary in the level of control that can be exercised. It is possible to operate them manually or use semi-automatic and automatic control. They also vary in capacity with some designed to handle high volumes and others to handle medium sized or small volumes. They have various ways of monitoring times, temperatures and color development.
A green bean is spongy and soft while a roasted bean is crunchy. The color, smell and density is changed by the roasting process. Chemical changes take place as beans are quickly brought to high temperatures. As soon as they reach a certain point, they are cooled down to stop the process. It is a matter of seconds between perfection and a ruined batch.
There are many variables that have to be taken into account in the roasting process. Some of these are the moisture content, the batch size, the start temperature and the cooling time. Times and measurements are taken before, during and after the roasting process and recorded.
The beans emit a cracking sound when they are heated. The beginning and end of the first crack and second crack as well as the length of time between the two are usually measured. This is used to determine timing for different roasts. Color changes are noted, the most significant one being when color turns to yellow and the browning process begins. The beans swell when heated but at the same time their weight is reduced.
Adjustments are made to times and temperatures in order to fully capture the sweetness, acidity or body of a certain variety. A roast profile is created for each variety and this helps to establish consistency between different batches. Each type of roast is given a special name.
Coffees are coming into their own as complex and flavorful beverages. Companies, both large and small, are devoted to producing the best quality roasts and selling equipment for roasting. The perfect roast is very much a matter of personal taste. It is possible to find excellent roasts online and they come in types to suit many different tastes, varying from light and medium to medium-dark or dark. One can also shop for the most modern roasting machines, easily comparing types and prices.
