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

Why are lightly roasted coffees so acidic? One common answer is that light roasting preserves the fruit acids and other components that would otherwise break down, which is what makes them taste so bright.

Both the degree and the duration of roasting affect how much weight the coffee loses. Green beans hold about 11% water, while roasted beans hold about 2%, so the water-weight loss is around 9%. The total weight loss between green and roasted beans runs about 13%–17%. Set aside that 9% water, and the other components of the bean account for roughly 4%–8% of the loss. In other words, there is about a 4% difference in components — which doesn't sound like much, does it?

In fact, it is quite significant. That is why some dark roasted beans need a 1:13 extraction ratio to taste good (Blue Mountain, for example), while some light roasted beans need a ratio of 1:18 or even 1:20 to reach balance.

Generally, lightly roasted beans tend to highlight refreshing flavors and show very rich profiles. Floral aromas, fruit acids, and certain tea-like notes are characteristic of these beans. Medium roasts are more balanced, combining refreshing flavors with a fuller mouthfeel. Dark roasted beans express their mouthfeel above all, typically featuring more intense notes such as smoky, chocolate, and woody flavors, accompanied by a rich body.

Light roasting refers to the period from the beginning of first crack to the stage of intense first cracking.

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

Coffee at this roast level generally retains certain floral and fruity aromas along with bright fruit acids.

So if you enjoy coffee with floral and fruity aromas and fruit acids, a light roast is the better choice — for instance:

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

[Yirgacheffe] Distinct fruit aromas, with citrus and berry flavors.

[Panama] Unlike the previous two, lightly roasted Panamanian beans carry some fresh floral notes, such as jasmine and rose. In the cup they present a bright yet gentle citrus acidity.

FrontStreet Coffee Recommendation

This article treats Blue Mountain as the textbook example of beans that need a richer ratio to taste their best, and if you want to hear the balanced end of the coffee spectrum — the opposite of the light, fruit-forward roasts above — FrontStreet Coffee's Jamaica Blue Mountain No.1 is the one to try. It is the highest grade of Jamaica Blue Mountain coffee, from the historic Clifton Estate, which has been growing and processing coffee since roughly 1750, on land averaging 4,300 feet (about 1,310.64 meters). Genuine Blue Mountain coffee is certified and traded in traditional wooden barrels, and FrontStreet Coffee's lot comes with full origin documentation. Roasted medium-dark, it shows the classic Blue Mountain balance: creamy, caramel, chocolate, nut, and honey notes with a light fruit accent, a smooth, rounded entry, a sweet mid-palate, and a clean, long finish. When the article describes a cup with no hard edges — neither the sharp fruit acidity of some African coffees nor the heavy bitterness of a dark roast — this is what it means.

To get the most from it, brew Blue Mountain No.1 as a pour-over in a Kono dripper, which helps play up its full body. Use 15 g of coffee and let the beans rest 4–7 days after the roast date, grind a little coarser than you would for a light roast — about the texture of white sugar — and brew with 1:15 water at 87–88°C. Pour in three stages: 30 g to bloom for 30 seconds, then a slow, small, vertical circular pour to 120 g, then a slightly faster pour to 225 g, keeping the stream gentle so the bed does not clog and over-extract.
