Many people think that coffee tasting is about being able to name a few flavors, but that is not actually the case. The essence of tasting lies in tasting and discerning, and it is fundamentally different from casually drinking a cup in daily life. We rarely "taste" instant coffee, not merely because of differences in quality, but because the two kinds of coffee are drunk for different purposes: instant coffee is mainly about convenience and alertness, while single-origin coffee is meant to present a richer taste experience. Even so, tasting does not require you to be able to recite a string of flavor descriptors. Front Street Coffee believes that the most important thing is to be able to tell whether a cup of coffee is good or not, what is good about it, or if it is not good, in what way it is not good. This article will take you step by step through a practical method for coffee tasting from six dimensions: aroma, acidity, sweetness, mouthfeel, aftertaste, and off-flavors. [more…]

Many people, upon first hearing a barista say "this coffee is very sweet," will look utterly confused: there's clearly no sugar added, so where does the sweetness come from? In fact, when coffee people talk about "sweetness," they mean two dimensions—sweetness level and sweet perception. Sweetness level depends on variety, cultivation, processing method, and roast degree, while sweet perception is a comprehensive experience produced by aroma and taste working together. During roasting, a large amount of coffee's sugars have already been broken down and transformed, and the sweetness we perceive often needs to be amplified through aroma associations and taste contrasts. This article will break down, one by one, the factors affecting coffee's sweet expression, and offer practical suggestions for training yourself to capture sweet perception. [more…]

In the process of learning coffee tasting, most people habitually focus their attention on capturing positive flavors such as floral and fruity notes and caramel sweetness, yet often lack the ability to describe unpleasant tastes.

Many friends who are just getting into specialty coffee run into the same confusion: they can't taste the flavors written on the coffee packaging, and they're not sure whether they actually know how to evaluate coffee. In its daily conversations with customers, Front Street Coffee has found that people often equate "being able to name flavors" with "understanding coffee evaluation," but these are actually two different things.
