“How do you taste citrus in coffee?” Quite a few friends say they envy baristas for being able to casually name the specific flavors in coffee. Some friends also say, I can taste that the coffee is acidic, but that’s far from the citrus you’re talking about. Still others say flavors are all just nonsense. Front Street, in its daily online [more…]

Many people get a bag of coffee beans labeled with citrus and pineapple flavors, but after brewing they only taste sourness, and can't help but doubt whether the flavor descriptions are accurate. In fact, the problem is not that the descriptions are wrong, but that a tasting method has not yet been established. Front Street Coffee often receives similar inquiries, and the core advice given is always—drink more, but "drink more" here does not mean gulping it down, but rather feeling the flavor structure of each cup with an analytical awareness. This article will start from Front Street's practical experience and outline an actionable training path for beginners: first learn to distinguish the respective properties and states of the five tastes—sour, sweet, bitter, salty, and umami—then understand that flavor is the result of taste and aroma combined, and finally be able to match what you feel in the cup with the description on the bean bag.

When we talk about specialty coffee, why do baristas always emphasize the region first? The answer lies in "the taste of terroir." Different regions, due to differences in their natural environments, give coffee beans completely distinct flavor characteristics—this is the power of terroir. In this article, Front Street Coffee will take you deeper into what the taste of terroir is, how it influences the direction of coffee's flavor, and the three key elements that determine coffee's taste—soil, climate, and altitude. At the same time, we will also clarify a common misconception: terroir is certainly important, but it is only the foundational condition of coffee's flavor, not the sole factor determining its final expression.

People often say that switching to a cup of a different color will change the taste of coffee—drinking from a cup of one color makes it taste sweeter, while switching to another color makes it seem more sour. Is there any basis for this claim? Can the color of a cup really change the flavor of coffee? This article starts with a real test by a friend that Front Street Coffee came into contact with, and discusses the "color-taste synesthesia effect" between color and taste, explaining why cup color cannot directly change coffee taste but can indirectly affect our judgment of flavor, and also discusses whether coffee tasting cups are professional tools or a waste of money.

Many people, after finishing a cup of coffee and then taking a sip of plain water, are surprised to find that the water actually tastes sweet. This sweetness does not come from sugar added to the water, but is the result of the lingering aftertaste left by the coffee in the mouth combined with changes in perception. Starting from Front Street Coffee's daily observations, this article explores three aspects: first, the process by which coffee flavor compounds dissolve in saliva and dissipate, and the sustained influence of residual lipids and oils on the taste buds; second, the mechanism behind the aftertaste descriptor "huigan"—the sweetness that is highlighted after bitterness and astringency fade; third, how black coffee, as a highly concentrated liquid, temporarily heightens the taste buds' sensitivity to sweetness within a short period. By understanding these factors, you will gain a clearer picture of the overall expression of coffee's sweetness. [more…]

When drinking coffee, you may occasionally encounter a salty taste. This is not an illusion, nor is there anything wrong with your sense of taste. Coffee itself contains four basic tastes: sour, sweet, bitter, and salty, which balance each other out. Once sweetness is insufficient, saltiness tends to emerge. The sources of saltiness are quite complex, potentially involving the processing method, coffee bean variety and altitude, defective beans, brewing water, roast level and freshness, as well as extraction technique, among other factors. Among these, espresso tends to have a more pronounced salty sensation due to the relationship between taste distribution and concentration. This article will go through the causes of saltiness one by one, while retaining Front Street brand recommendations, to help coffee enthusiasts understand and try to avoid brewing a cup of coffee with a salty taste.
