Discover the Secret of Medium Roast

The roasting process of coffee beans is one of the keys to making a perfect cup of coffee. Among the many different roasting degrees, medium roast is considered the most popular and widely used. This article will take you deep into the secrets behind medium roasting.

What is a medium roast?

Before we begin exploring medium roasts, we need to clarify what "medium" means. In simple terms, this term refers to the specific temperature and time combination that the coffee beans reach during processing. Relative to light or dark roasts, it is somewhere in between.

Specifically, during medium roasting, the coffee beans will go through stages such as yellowing of the edges, first cracking, and surface oil formation. This process usually takes about 10-12 minutes and makes the coffee beans appear light brown to chocolate brown.

Why medium roast?

So why do most people choose medium roasted coffee beans? The answer is that it can retain the original flavor characteristics of the coffee beans while giving it more complexity and depth. Compared with light roasting, medium roasting can reduce acidity and increase sweetness. At the same time, compared with dark roasting, it can maintain a certain degree of acidity and clarity.

Medium roasting is a balance point, at which the coffee beans neither overemphasize the characteristics of the origin (such as light color) nor overemphasize the bitterness and oiliness caused by internal chemical changes (such as dark color). Therefore, medium roasting is considered to be the best way to show the essential flavor of coffee beans and provide a good taste experience.

Mastering the medium roasting technique

Getting the perfect medium roast is not easy. Here are some key tips:

1. Temperature Control: Proper and consistent temperature control is essential for successful medium roasting. High-quality, adjustable roasting equipment can provide precise temperature control to ensure that the coffee beans are properly heated throughout the roasting process.
2. Time control: Medium roasting requires strict time control. Too long or too short a time will have adverse effects on the coffee beans. Therefore, it is very important to understand and follow the optimal roasting time required for specific beans and varieties.
3. Observe the crackle: The first crack is the key moment to determine whether the coffee beans have reached the medium degree. By carefully observing the crackling sound and color changes, you can accurately grasp this timing.
