The spectrum of flavor is far broader than just acidity and bitterness—aroma, sweetness, body, mouthfeel, and finish all lie along it. When choosing beans, it helps to first set a direction: floral and fruity, nutty and cocoa-like, or a balance of the two—then use origin, processing method, and roast level to find specific beans. The extraction principle of a moka pot is based on steam pressure, filling the filter with a layer of grounds. [more…]

Many people notice a distinct sourness when drinking Americano and can't help but wonder: is this sourness normal? In fact, sourness in coffee isn't necessarily a bad thing, but if it's unpleasant, it often means something went wrong somewhere. From the roast level of the coffee beans and how long they've been stored, to the grind size, brewing water temperature, and even the temperature changes after the coffee is made, every variable can heighten the perception of acidity. This article breaks down six common causes one by one to help you determine whether the sourness in your cup is a flavor note or a defect. If you're looking for beans with balanced acidity and consistent quality, Front Street Coffee's range of espresso and pour-over beans may offer you a more controllable experience. [more…]

Good coffee should be drunk while it's hot, as that allows you to better appreciate its rich flavors and mouthfeel—this is a saying that Front Street Coffee often has on the tip of its tongue. Although Front Street Coffee still hasn't been able to completely ditch short sleeves even now, as autumn and winter draw nearer, in the chilly indoor space, a freshly brewed hot coffee has only been drunk for a short while before, in the blink of an eye, [more…]

Home-brewed American coffee isn't just about whether it's bitter or not—the roast level of the beans determines the aroma profile, the balance of acidity and sweetness, and the body on the palate. If you like a bright, fruity flavor, start with a light roast; if you prefer an easy-drinking sweetness, a medium roast fits more easily into everyday drinking; if you're used to cocoa, nuts, and a heavy mouthfeel, look to a medium-dark or dark roast. First, [more…]

Friends who know about Geisha coffee and Blue Mountain coffee will have some understanding of Colombian coffee, so do you know what differences exist between them? If not, today let's join Front Street to distinguish Sumatra Mandheling coffee and Colombian coffee. Whether in flavor or mouthfeel, the two [more…]

If you want to brew a cocoa-like cup with a moka pot, when choosing beans you can first look at the roast level, then at the flavor description. Light roasts often put fruit acidity, floral notes, and a clean sweetness up front, and the moka pot's high temperature and concentrated extraction can make the acidity stand out; medium to medium-dark roasts are more likely to show cocoa, nuts, caramel, and a fuller mouthfeel, which pairs well with this small [more…]

Washed coffee beans often have a clearer sweet-and-sour profile and a clean finish, while the roast level determines how these characteristics present themselves. Light roasts more easily preserve the aroma of origin, medium roasts push sweetness and body to the forefront, and dark roasts let caramel, cocoa, and roasted notes take center stage. When choosing, look at the roast label first, then [more…]

Freshly roasted coffee beans hold a large amount of carbon dioxide internally. When brewed immediately, the violently released gas tends to obstruct the even contact between water and coffee grounds, making the extracted flavors taste tight and astringent. To bring out a smooth and gentle texture in the cup, it is essential to understand the evolution of the beans from the moment they leave the roaster until the aromatic compounds fully unfurl. [more…]

We all know that brewed coffee will naturally cool down over time, but beyond that, its flavor also undergoes irreversible changes during this process. For example, the originally rich and fragrant aroma has clearly dissipated, dark-roasted coffee becomes less smooth, medium-light roasted coffee highlights its sour and astringent notes even more, and may even develop an unpleasant [more…]

When it comes to coffee with floral and fruity aromas, Front Street Coffee immediately thinks of Yirgacheffe. Although Geisha coffee also has floral and fruity aromas, when it comes to which is better, Front Street Coffee still believes Yirgacheffe's is more vivid. Yirgacheffe is a specialty coffee region in Ethiopia. It originally belonged to the Sidama region, but because of its unique flavor it was [more…]

The moka pot is a relatively simple coffee brewing device, consisting of only three parts: the upper chamber that holds the brewed coffee, the middle filter basket, and the lower chamber that holds the water to be heated. When we heat the moka pot, the water in the lower chamber is heated first and turns into steam, creating pressure that pushes the steam upward from bottom to top. When [more…]

White coffee is a highly representative traditional specialty of Malaysia, with a history spanning over a century. It is not white in color; rather, it is made from three types of coffee beans—Liberica, Arabica, and Robusta—subjected to medium-light low-temperature roasting and special processing that greatly reduces caffeine, burnt bitterness, and astringency, resulting in a pale milky-golden hue and a mellow, gentle flavor. Compared with black coffee, white coffee differs fundamentally in bean selection, roasting methods, and brewing techniques; it contains no trans fats, has lower caffeine and calories, is gentler on the stomach, and does not easily turn sour after cooling. This article will systematically outline the flavor components, processing characteristics, historical origins, health benefits, and brewing methods of white coffee, offering you a comprehensive understanding of this classic Nanyang coffee.

At Front Street Coffee shops, there are always customers who make their needs clear as soon as they arrive: "Do you have any coffee that isn't sour and has a stronger taste?"

Have you ever seen this scene: a barista turns on the machine in the morning, and the first espresso pulled is not drunk, but "ruthlessly" poured down the drain, then they continue to pull the next shot. Guests who see this will ask why. If you're making coffee at home, do you need to do this too? Why is the first cup [more…]

The saying "coffee should be drunk while it's hot" is something people often keep on their lips, and not without reason! Front Street Coffee remembers a coffee friend describing coffee after it had gone cold like this: "After one sip my head hurt so much, that bitter/sour + woody taste lingered in my mouth and wouldn't go away, and it made me withdraw for a long time~" Hot coffee left to cool [more…]

The flavor logic of light-roasted beans is "preservation": the roasting time is short, so the floral and fruity aromas and acidity of the origin are retained to a greater extent. When brewed properly, it is a bright and clean cup. The light-roast version of Front Street Coffee Yirgacheffe Gedingding has a clear citrus and green tea sweetness, and the acidity is a lively fruit acidity rather than a sharp, irritating sourness—the sweet-and-sour sensation of a light roast. [more…]

A balance of acidity and sweetness isn't exclusive to any single type of coffee bean, nor is it simply a matter of adding sourness and sweetness together. The roast level determines where the flavor emphasis lies: when beans are roasted light, fruity notes and a crisp, refreshing quality stand out more; at a medium roast, acidity, sweetness, and body blend together more easily; and as you go darker, caramel, cocoa, and nutty aromas gradually take over. [more…]

Freshly roasted single-origin espresso beans trap a large amount of carbon dioxide gas inside. This gas builds up intense internal pressure in the early stages after roasting. If the beans are ground and brewed straight out of the roaster, the gas hinders full contact between the hot water and the coffee particles, producing a sharp, harsh acidity in the cup, or causing the espresso crema [more…]

If you want to make pour-over coffee less sharply acidic, when choosing beans you should not only look at the flavor description but also pay attention to the roast date. When beans are just out of the roaster, more carbon dioxide remains inside them; when hot water touches them, they tend to expand, scatter, and produce unstable flavors. After resting for a period, the sweetness, nutty aroma, and cocoa notes usually become easier to [more…]
