Each of the best coffee roasters in London use their own coffee roasting methods and approach when it comes to coffee roasting procedures and Technics.
Coffee roasting is the process of heating the coffee cherry seeds to change or bring out the aroma and flavor and, ultimately, increase solubility.
Solubility is the essential element of coffee brewing
The rate of solubility of compounds in a specific roast is the key to achieving the right extraction through temperature, time and grind size.
In order to get to solubility, coffee is roasted, typically in a commercial roaster. However, coffee can also be roasted in a popcorn popper or a cast iron pan.
What happens when coffee is roasted?
All coffee beans will go through five stages of roast.
These stages of roast profile occur along a temperature spectrum that will be unique to each of the beans by varietal, region, and altitude. The following are the usual stages of roast:
- Drying or Yellowing: a crucial phase, this will determine the overall batch time. It is driven by the initial moisture content of the beans and sets the foundation for all of the other stages, indicative of how hard or soft, fast or slow your roast is driven into the rest of the stages.
- Maillard Reaction: is the first “browning” of the coffee. This reaction is the catalyst for the formation of many of the 1,000 volatile chemical compounds that are created during the coffee roasting process. These compounds are easily evaporated in the air, and therefore contribute to the aroma of coffee. This process is most closely associated with the aroma of baking bread, as well.
- First Crack: while the early roasting phase is all about heat acting upon the coffee bean from the outside in, “first crack” is the initial part where pressure from moisture evaporation and heat has built up inside the bean and begins to break the bean down from the inside out. It is an audible sound, like popcorn popping. However, it usually produces no cracks or explosions.
- Second Crack: darker roasted coffee will sometimes be roasted through a second crack, which is nearing the full breakdown of the coffee.
- Carbonization: full breakdown. Fire hazard.
