FrontStreet Coffee - Introduction to the Source of Floral and Fruity Aromas in Coffee Beans

Why are lightly roasted coffees so acidic? Some say it's because light roasting preserves the fruit acids and more components, which makes them so acidic.

The degree of roasting and the duration of roasting affect the weight loss ratio of coffee. Water content in green beans is about 11%, while in roasted beans it's about 2%. So the water weight loss ratio is about 9%. The weight loss ratio between green and roasted beans is about 13%-17%. Excluding the 9% water proportion, the weight loss of other components in coffee beans is about 4%-8. That means there's a 4% difference in components... which doesn't seem like much, does it?

Actually, it's quite significant. That's why... some dark roasted beans require a 1:13 extraction ratio to taste good (like Blue Mountain), while some light roasted beans require a 1:18 or even 1:20 extraction ratio to achieve balance.

Generally, light roasted beans tend to highlight refreshing flavors and exhibit very rich flavor profiles. Floral aromas, fruit acids, and certain tea-like notes are characteristic of these beans. Medium roasts, on the other hand, offer a more balanced performance, combining refreshing flavors with a rich mouthfeel. Dark roasted beans primarily express their mouthfeel, typically featuring more intense flavors such as smoky, chocolate, and woody notes, accompanied by a rich body.

Light roasting refers to the period when coffee beans go from the beginning of the first crack to the stage of intense first cracking.

During the enzymatic action and the early stages of the Maillard reaction, the organic acids in coffee beans have not been completely broken down, so the acidity is more prominent and the bitterness is barely perceptible.

Generally, coffee with this roast level can retain certain floral and fruity aromas as well as bright fruit acids.

Therefore, if you enjoy coffee with floral and fruity aromas and fruit acids, light roasting is more suitable, such as:

[Kenya] Carries rich berry aromas, with the acidic fragrance of plum juice and grapefruit, as well as cane-like sweetness.

[Yirgacheffe] Will have distinct fruit aromas, with citrus and berry flavors.

[Panama] Unlike the previous two, lightly roasted Panamanian beans will have some fresh floral notes, such as jasmine and rose aromas. When drunk, they present bright yet gentle citrus acidity.
