What is Coffee Roasting?

Coffee Roasting is a strategically orchestrated chemical process that turns raw coffee into fragrant, appealing coffee beans that we know and love. Coffee roasting is a pure blend of science and art. It involves careful application of heat to turn “raw green” coffee beans into brown aroma-filled coffee beans that are consumed worldwide. Before the process of coffee roasting the coffee is in a green raw state that is neither aromatic nor consumable.  

The process of roasting involves high heating which triggers chemical reactions to take place in green coffee beans as they are brought to high temperatures. When they reach their peak temperatures the beans are cooled down eventually bringing the process to a halt. Roasted coffee beans carry the aromatic coffee smell and they also have a crunchy feel to them. Once the roasting process is over they are ready to be brewed and consumed. 

However, as one of the most reputed Melbourne Best Coffee Roasters we always suggest consuming freshly roasted beans as soon as possible as with time they start to lose their fresh roast aroma. 


Is Coffee Roasting tough?

We are no one to determine the complexity of the coffee roasting process but as the Best Coffee Roaster Melbourne, we can say with confidence that it is pure art. It is a precise process where a split second can determine the fate of your coffee batch. 


Two Methods of Roasting

Drum Roasting and Hot Air Roasting are the two most commonly used methods of coffee roasting. Here’s what they are:


Drum Roasting


When compared to Hot Air roasting, Drum Roasting is normally done on a lesser scale. Small batches of coffee are exposed to a temperature of 230 degrees for around 12 minutes. Slow roasting removes all of the beans' acidic tastes.


Hot Air Roasting

Because drum roasting takes longer and produces less coffee, the coffee industry uses the Hot Air Roasting process, also known as industrial roasting, to meet global coffee demand.

For around three minutes, a huge batch of coffee is heated at extremely high temperatures in a stream of hot air. Industrially roasted beans, on the other hand, have a more acidic flavour.


Types of Coffee Roasts

The colour and overall visual appearance of roasted coffee beans depend upon the duration of the roasting process and their exposure time to the heat. Based on the roasting intensity levels coffee roasts are primarily divided into four categories that are:


Light Roasts

These are light brown in colour and they are used for milder coffee varieties. They are dry on the surface because they are not heated long enough for the inner oil to break through the surface.


Medium Roasts


This roast batch is medium brown in colour and it also does not have any oil on the surface. This coffee roast is mainly used in the US.


Medium-Dark Roast

This coffee roast is medium dark in colour and it has a little bittersweet aftertaste. They also have a little amount of oil on top as they are heated long enough for the oil to break.


Dark Roast


This coffee roasting process produces black coffee beans that are highly bittersweet and oily in nature. Darker the batch, the less acidity content it will contain.
