Like fruits, coffee is not the thing that you can just pick off and devour. The cup of coffee that you make and consume so easily, yet the whole journey of this coffee reaching from the plant to your cup is actually an extensive process.
The coffee beans need to be first roasted before they can be packaged and sold to the consumers. There are multiple methods of coffee roasting and they vary from simple to complex coffee roasting.
Importance of Coffee Roasting
If you want to obtain the perfect flavor and aroma of green coffee beans, you roast them. Coffee beans are kept green, it is a condition where their impeccable quality and taste can be preserved.
A green bean lacks the qualities and features of a roasted bean. A green bean is spongy and soft to bite. It has a grassy smell to it.
Heating & Cooling Down
When coffee beans are roasted, chemical reactions occur as the beans are brought to extreme temperatures. Once they are at the top of perfection, they are cooled down immediately so that the process can be stopped.
The smell of roasted beans is like coffee. Their weight is less because the humidity in the beans has been dried out. Roasted beans are crunchy as opposed to soft and spongy, they are set to be ground and then brewed eventually.
Once the beans have been roasted, they should be consumed at the earliest as they are no more in a green state where the flavor and quality can be preserved. They can lose the fresh flavor quickly if left for long time.
Coffee Beans Before Roasting
You must have pondered every now and then that how would the coffee beans look like before they reach you in an impeccable ground state? The fact is, before roasting the coffee beans are green. They have no smell but an earthy aroma.
It is this roasting process that gives the coffee its rich and strong aroma and flavor that you get in your cup of coffee. Heat is absorbed by the coffee beans during the process of roasting which darkens the color of coffee beans.
The Cracking and Roasting Process
When the temperature is extreme, oils appear on the beans’ surface. Beans start to crack and expand at the temperature of 401 degrees Fahrenheit. At the temperature of 437 degrees Fahrenheit, they crack for the second time.
It is important to know that the beans must not be roasted above the temperature of above 482 degrees Fahrenheit because above this temperature, their taste will be ruined, they will get burnt and also thin out.

The Art of Roasting
Roasting is, without a doubt, an art. A skilled roaster has the expert potential to “read” the coffee beans and make decisions in a matter of seconds. There is a thin line between making a perfectly roasted coffee and ruining a batch of coffee.
Types of Roasts
If we speak in a general manner, then there are three types of roasts. Regardless of what your coffee is called, such as the French roast, breakfast blend etc., it will fall in 4 major categories which are:
- Light roast
- Medium roast
- Medium dark
- Dark roast
Let us discuss in detail the different types of roasts.
The light roast is also called first crack. This name was given because the beans are in the primary stages of expansion and cracking. These beans look pale, dry and the resulting coffee produced is light-bodied.
Flavor of Light Roast
These beans are a tad bit acidic. The coffee does not show any hints of roasting. Light roast coffee does not mean that the flavor would be watered down and diluted. It is in fact the opposite; the roast is light yet it is aromatic. It even has floral or fruity notes.
With these roasts, the beans should not have an oily surface. This is because they are not heated enough for the oils to break through to the top. Otherwise it will be a different kind of roast.
Color of Light Roast
The color of light roast is light brown (as the name indicates) and is used for mild coffees. It is important to note that since it’s not roasted at extreme temperatures, the light roast has the flavor of original beans.
Coffee varieties that use light roast are as follows:
- Half City
Medium roast beans have a dry look and feel. However, they have a sweet profile.
Flavor of Medium Roast
To be precise, roasting beans for a longer time gives more aroma and flavor to the beans. It has less acidity as compared to the first crack. The flavor profile is a bit more concentrated but you do get a fuller body.
Don’t think that a flavor profile that is concentrated is bad. This is best for the people who have an affinity for distinct bitterness.
Preferred by Most Americans
A lot of consumers feel that this roast has perfect blend of acidity, aroma and the flavors. Most of the Americans prefer this roast.
These beans are medium brown in color with a strong smell. However, there is no oil on the surface. This roast is obtained at 428 degrees Fahrenheit. The weight of the beans is lost about 13% during this process.
Pyrolysis (thermal decomposition that results from roasting) has an effect on the chemical composition of the beans. It is also somewhat responsible for the stronger flavor.
Coffee varieties that use medium roast are as follows:
Medium Dark Roast
The color of medium dark roast beans is dark brown. They have oil on their surface.
Due to roasting for longer periods of time, all the acidity is destroyed. Thus, most of the aromas of beans is revealed.
