Roasting is one of the most important steps in the journey of a coffee bean. It transforms raw green coffee into the aromatic, flavorful beans we brew every day. But the roast level — whether light, medium, or dark — has a huge impact on the flavor, aroma, body, and even caffeine content of your cup.

In this article, we explore how each roast level tastes and which brewing methods they suit best.

🔥 1. What Is Coffee Roasting?

Roasting is the heating process that:

• Turns green beans brown

• Creates aroma and flavor

• Reduces moisture

• Develops natural sugars

From fruity and bright to smoky and bold — the roast level determines everything.

🌕 2. Light Roast — Bright, Fruity, and Complex

Light roasts preserve the true origin flavor of the coffee bean.
Farmers and specialty roasters often prefer this roast because it highlights the bean’s natural qualities.

It has more caramelization and less acidity, making it perfect for most coffee drinkers.
