Coffee and tea are both beverages that rely on water to dissolve flavor, so if tea leaves can be steeped repeatedly, can coffee grounds do the same? In terms of composition, about thirty percent of coffee beans is soluble matter, which theoretically does support multiple extractions. In practice, however, the coffee liquid obtained from repeated brewing tends to be thin and carry off-flavors. The reason is that a normal extraction has already released most of the sweet and sour essence, and the remaining substances cannot support good flavor. This article will start from extraction yield and the order in which flavors dissolve to explain why coffee grounds are single-use, and to clarify why pour-over and drip-bag coffee are not recommended for repeated brewing.

Kopi Luwak is hailed as the "aristocrat" of coffee, renowned for its distinctive minty coolness and syrupy consistency. However, behind this expensive drink lies a distressing and cruel truth.

Front Street Coffee takes you through the origins and flavor characteristics of Kopi Luwak, and why we should no longer consume this kind of coffee. At the same time, Front Street also recommends coffees from other excellent regions, so that while enjoying deliciousness, you can also make a more humane choice. [more…]

Many coffee enthusiasts, upon getting freshly roasted beans, can't wait to brew a cup, only to find the flavor flat, the body thin, and even a dry, uncomfortable throat afterward. The key behind this lies in the large amount of carbon dioxide remaining inside the coffee beans after roasting, as well as the smoky, pungent sensation brought by high-temperature roasting. This article will delve into why fresh coffee beans need to "rest" before brewing, how carbon dioxide interferes with the extraction process, and the true source of that dry throat sensation. At the same time, Front Street will also share a few practical methods to help you still brew a relatively ideal flavor even when the beans are too fresh. [more…]

In pour-over coffee, keeping the coffee bed level is a prerequisite for even extraction, and many enthusiasts are in the habit of tapping or shaking the dripper to level the grounds. Yet hidden behind this gesture is an easily overlooked problem: the vibration causes fines to migrate downward through the gaps between the coarser particles, forming a dense layer at the bottom of the dripper while leaving fluffy coarse grounds on the surface. This structural change not only alters the appearance of the coffee bed but also directly affects the degassing effect during the bloom stage. Through comparison charts and actual brewing photos, this article breaks down in detail the changes in fines distribution caused by tapping the dripper, and explains their practical impact on subsequent brewing, to help you make more sensible judgments when leveling the coffee bed.

When you buy freshly roasted coffee beans, many people habitually squeeze the bean bag and bring their nose up to the small hole on the packaging to take a deep whiff of the aroma. This hole is actually a "one-way degassing valve," and its existence serves a clear engineering purpose—it only allows gas to escape and does not let outside air in. This article will explain in detail how the degassing valve works, why it is not meant for squeezing to smell the aroma, and how to use the characteristics of the degassing valve to extend the coffee beans' peak flavor period.

Kung Fu Coffee, which once made a high-profile debut with the concept of "Eastern tea plus Western coffee," quietly shut down its first national store at Shenzhen's Wongtee Plaza just seven months after opening. Incubated by the team behind "Benlai Buyingyou," the brand's first store was said to have cost over six million yuan to build, and it briefly became an internet-famous check-in spot thanks to its purple interiors and Chinese-element design, reaching an average daily output of 1,200 cups within ten days of opening. Yet consumer reviews were sharply divided, and coupled with the awareness and talent bottlenecks facing the tea-coffee category itself, Kung Fu Coffee's next moves are drawing close attention.

Many people, when first encountering iced pour-over, have this thought: since hot americano uses hot water and iced americano uses ice water, then if hot pour-over uses hot water, shouldn't iced pour-over just use ice water directly?

Using a moka pot to brew estate-grade single-origin beans strikes many people as a waste of good coffee: shouldn't good beans be used for pour-over? But if you look at it from another angle, the moka pot is a very low-barrier high-concentration extraction device for home use, and expressing estate beans in a different way often reveals a side you can't see in pour-over. This round of experiments is about taking a few [more…]

Berry-forward coffee beans often burst with aroma right after roasting, yet on the palate they can seem sharp, scattered, and may even carry a hint of roast character. Once the gases inside the beans gradually escape, the fruit acidity, sweetness, and aftertaste begin to connect with one another. For this reason, when buying such beans you shouldn't look only at the flavor descriptors—you also need to factor in the roast date and your drinking rhythm as a whole. [more…]

Tropical fruit flavors are often the most alluring part of coffee beans: the sweet aroma of ripe fruit, bright acidity, and an aroma that unfolds like fruit juice once it hits the palate.

After roasting [more…]

First, distinguish " [more…]

Finally, Front Street will also share its consistent advice on "hot vs. iced." [more…]

When the coffee bed doesn't bloom during a pour-over, many people take it as a direct sign that the beans aren't fresh—but the reality is far more complicated than that. Front Street Coffee believes that whether the bed expands can serve as a reference, but it shouldn't be relied on too heavily. Factors like roast level, grind size, and bean hardness all affect how much the bed puffs up during blooming. Dark-roasted beans often produce a full, domed "hamburger," while light-roasted beans—especially high-altitude Geisha—may only rise slightly or not at all, yet still deliver excellent flavor. This article breaks down these variables one by one to help you understand more accurately what's really behind blooming expansion, and avoid misjudging how fresh your coffee beans are. [more…]
