Light roast

Light roasting is the lightest type of coffee roasting. At this stage, the surface of the coffee beans has just changed color and turned light brown. Roasters need to control the temperature and let the coffee beans experience high temperature in a short period of time to retain the acidity and moisture inside the coffee beans, giving the coffee a bright luster.

Lightly roasted coffee has a bright taste, prominent acidity, and fruity aroma. This kind of coffee tastes fresh and refreshing, leaving a long-lasting aftertaste. Lightly roasted coffee beans are also more likely to release carbon dioxide, which helps to enhance the overall flavor of the coffee. On a hot summer afternoon, a cup of cold lightly roasted coffee paired with a refreshing snack is simply a real treat.

Medium Roast

Medium roasting is the most common type of coffee roasting. At this stage, the color of the coffee beans deepens further, showing a dark brown color, and some oily sheen appears on the surface. The control of the temperature needs to be more precise, ensuring that the coffee beans are fully developed without losing too much internal moisture.

Dark roast

Deep roasting requires higher temperature and longer time to allow more chemical reactions to occur inside the coffee beans, producing a richer flavor.

Deeply roasted coffee has a rich taste and prominent bitterness. It has a caramelized sweetness and woody aroma, making people feel the strength and depth of the coffee.
