Is the sourness in coffee good or bad? Some people believe that sourness means the coffee is not fresh, while others regard it as a hallmark of high-quality coffee. In fact, green coffee beans themselves are rich in organic acids, most of which decompose or disappear after roasting, leaving only a limited variety of organic acids in the final cup. The latest research shows that there are not many acids that our taste buds can clearly identify, and much of the fruity acidity we perceive actually comes from the combined association of sourness with other flavors. The latest SCA cupping form classifies acidity into two categories—"sweet type" and "dry type"—helping us more accurately judge whether a coffee's acidity is good or bad. This article, from the professional perspective of Front Street Coffee, will provide an in-depth analysis of the sources of coffee acidity and the criteria for evaluating it. [more…]

Many people believe that the lighter the roast, the more sour the coffee—but the truth is not that simple. The acidity in coffee comes from substances such as malic acid and citric acid that already exist in the green beans, and these are continuously generated and broken down during roasting.

This article begins with the principles of how acidity changes, and, combined with a comparative cupping of a Front Street Coffee Papua New Guinea washed Typica, explains the relationship between roast level and perceived acidity. It also recommends five coffees that naturally carry floral and fruity notes, including Front Street Coffee Fruit Ding Ding, Kenya Little Tomato, Strawberry Candy, Colombia Big Belly Button, and Flower Butterfly, to help acidity lovers find their ideal flavor.
