Coffee roasting degree analysis

The degree of roasting of coffee is one of the important factors that affect its flavor and taste. Different degrees of roasting will give coffee beans different colors, aromas, and tastes. This article will focus on understanding the degree of roasting of coffee beans and analyze it in detail.

Light RoaST

Light roasting is when the coffee beans are processed at a lower temperature for a shorter time, usually after the first crack. This process retains most of the original flavor and makes the coffee beans bright and acidic.

Lightly roasted coffee beans are usually light yellow or light brown, and may have some oil on the surface. They have a fresh and fragrant aroma, with obvious acidity and a fruity or floral taste.

Medium Light Roast

Medium-light roast is between light roast and medium-dark roast, also known as city roast. At this stage, the acidity of the coffee beans begins to weaken, and the aroma and sweetness gradually increase.

Medium to light roasts are darker in color, usually medium brown. They have a distinct aroma and a balanced taste, retaining some acidic characteristics while adding some sweetness.

Medium Roast

Medium roasting means that the coffee beans are processed at a higher temperature for a period of time. This treatment makes the coffee beans heat more evenly and produces more oil.

Medium roasted coffee beans are darker in color, usually dark brown. They have a rich and balanced aroma and taste, reaching a balance between acidity, bitterness and sweetness.

Medium Dark Roast

Medium-dark is somewhere between medium and dark, also known as full city or Americano. At this stage, the oils of the coffee beans begin to show and the acidity is almost completely gone.

Medium-dark roasted coffee beans are darker in color, usually dark brown. They have a rich, full aroma and taste, with increasing bitterness.

Dark Roast

Deep roasting refers to processing coffee beans at high temperature for a long time. This treatment produces more oil on the surface of the coffee beans and changes the internal structure.

Deep roasted coffee beans are very dark in color, usually dark brown or even almost black. They have a strong and intense aroma and taste, with a very prominent bitter taste.

Light roasting retains the original flavor and shows bright acidity; medium-light roasting increases sweetness and aroma; medium roasting achieves a balance of acidity, bitterness and sweetness; medium-dark roasting highlights the rich aroma and taste; and deep roasting brings a strong bitterness.
