It is generally believed that green beans determine 80% of coffee's flavor, while the remaining 20% is determined by roasting.

The most crucial key is determining which roast level to achieve. Over-roasted coffee beans will only highlight bitterness; while under-roasted beans will become too acidic. It is extremely important to master the optimal timing to stop roasting according to the characteristics of each bean. After understanding the ideal roast level for each type of bean, it will also help when purchasing roasted beans. If the shop changes roast levels according to different types of beans, you should be able to purchase delicious coffee beans from there.

● People who are not yet accustomed to drinking coffee tend to find light-roasted beans more delicious. It is recommended to start with entry-level light-roasted beans, then gradually try beans with darker roast levels.

Light Roast

Has acidity, emitting the original rich aroma of the beans

Light-roasted bean coffee has less bitterness and more acidity, with a taste similar to black tea. When you want to brew refreshing-flavored coffee or want to taste coffee that emits a gentle aroma, light roast is suitable.

Medium Roast

Suitable for beans with less bitterness and acidity, and mild flavor

Medium roast is the stage that can express coffee's bitterness and flavor, suitable for beans with rich aroma and mild taste. When conducting cupping to evaluate coffee flavor, medium roast is also used as the standard.

When roasting specialty coffee, in order to clearly present the unique aroma of coffee, most adopt light to medium roast. However, when wanting to express coffee flavor, there are also many beans suitable for roast levels above medium-dark.

Medium-Dark Roast

Can fully experience bitterness and acidity, a flavor preferred by Japanese people

Medium-dark roast coffee has the richest flavor, neither leaning toward bitterness nor acidity. Besides being loved by Japanese people, it is a roast level favored by people around the world. Suitable for beans with slightly thicker body.

Dark Roast

Heavy bitterness, emitting chocolate and caramel-like aromas

Dark roast is when beans are roasted to dark brown or turn black. The bitterness of coffee becomes most obvious, and the flavor appears somewhat monotonous. It is applicable when roasting beans with thick body and heavy acidity, or when brewing espresso.

Water temperature and grind coarseness both affect bitterness and acidity

● The delicate balance of coffee's bitterness and acidity is not controlled solely by roasting. Differences in coarseness when grinding beans, water temperature during extraction, extraction speed, etc., will all change the balance. Effort must be put into every stage to brew the flavor you love.

1. Water Temperature

If the water temperature is too low, coffee components cannot be fully extracted, only brewing coffee that leans toward acidity; conversely, if the water temperature is too high, the bitterness and off-flavors of coffee will become heavier.

2. Grind Coarseness (Mesh)

If coffee beans are ground into coarser particles, the brewed coffee concentration will be lighter, with acidity overpowering bitterness. If the particles are ground finer, the brewed coffee concentration will be stronger, with bitterness more prominent.

3. Extraction Speed

If extraction is fast, the coffee's acidity is heavier and the flavor is lighter. Conversely, slowly pouring hot water and extending the blooming time of the coffee grounds will result in coffee with heavier bitterness.

4. Extraction Amount

Using large amounts of hot water to brew multi-serve coffee makes it easier to brew a milder flavor; when using small amounts of hot water to brew few-serve coffee, it's easy to highlight the bitterness of coffee.
