Proper roasting techniques to achieve the best taste?
As far as I know, coffee is a special agricultural product. Currently, scientists around the world have found nearly 1,000 chemical compounds in coffee, most of which are aromatic compounds. And it doesn't seem to stop there. It's special, isn't it? So how do we roast a good batch of coffee to keep its original flavor?
What is the right way to roast coffee?
A coffee roaster is called a professional when the batches of coffee are roasted smoothly and evenly, and it is important to keep the best flavor after the coffee roasting process.
In fact, when properly roasted, delicious coffee beans turn out to be incredibly magical. That's why top roasters always test roast their coffee before deciding on official batches. And rather perhaps the formula too.
This shows us that coffee roasting is not just about roasting beans, but really an art.
How long is the roasting time for a batch of coffee?
It is difficult to say exactly how long it takes to roast a batch of coffee, although with Danielmachine roasting coffee takes an average of 12 to 20 minutes, depending on the type of roaster you use, the type and quality of coffee. the amount of coffee beans to be roasted and of course the purpose of the roast.

Leading to the post-roasting process is that the tasting and preparation will be incorrect, which leads to unpredictable consequences when your coffee reaches the customer.
The best roasters adjust the temperature of the roaster to create a variety of flavors and colors. Coffee roasted at a reasonable level will produce a very smooth bean, with a faint woody aroma; The European style is very aromatic and the Italian style is dark black with a taste that lingers in the mouth.
Coffee roasting is really an art
The art of professional coffee roasters is extremely delicate, reflecting individual tastes and preferences. Some coffee roasters warn that coffee should not be roasted too thoroughly because it will be deodorized. There are many different opinions when it comes to the right roasting temperature for the best coffee in the world.
For example, there are two schools of thought about Kenyan coffee beans. Some believe that they should be roasted thoroughly to reduce the natural acidity, becoming sweeter; on the contrary, others argue that a brief roast enhances the flavor and brings out the innate characteristics of the coffee. The "roast" school looks for harmony and consistency, the "roast" school is a sense of innate qualities, even potentially shocking for those who are not used to coffee.
