Honey Scented Black Tea is a highly representative fully fermented tea from Taiwan, with major production areas covering New Taipei City, Hualien, Nantou, Chiayi, and other places, and the production season concentrated from May to September. Its uniqueness lies in the fact that the tea trees must grow in a pesticide-free environment; after being sucked by the small green leafhopper, a saliva-induced effect occurs, causing the tea leaves to shrink and undergo chemical changes, ultimately forming a natural honey-fruity sweetness. Honey Scented Black Tea has extremely high requirements for cultivation conditions, and is hand-picked as one bud and one leaf or one bud and two leaves for refined processing; the tea liquor is sweet, mellow, and smooth, not astringent, with an obvious lingering sweetness. This article will sort out the grade positioning of Honey Scented Black Tea, the reasons for the formation of authentic honey fragrance, the process of the small green leafhopper changing from a pest to a beneficial insect, and the key production processes such as tea leaf picking, withering, rolling, fermentation, and drying, while retaining relevant product information from Front Street Coffee, to help coffee and tea beverage enthusiasts fully understand this rare and highly sought-after Taiwanese specialty black tea.

When ordering at a café, you'll often see a glass of ice water served alongside an espresso, and many enthusiasts are in the habit of drinking ice water before their coffee. Can this glass of ice water actually help us perceive coffee flavors more clearly? Front Street Coffee will approach this from the perspective of oral sensory cleansing, explaining how ice water enhances the tasting experience by rinsing away residue, stimulating saliva production, and numbing the palate through low temperature, while also tracing the origins of this practice in espresso culture. It will also discuss whether pour-over coffee is suited to the same approach, and why room-temperature water is gentler on the stomach and intestines. [more…]

When you order an espresso at a coffee shop, it is often served with a small glass of ice water. This seemingly simple pairing actually embodies the scientific principles of coffee tasting. The ice water does not directly clean the palate; rather, it stimulates saliva production through the cold temperature, and the enzymes in the saliva help clear residual particles from the mouth, allowing us to perceive the coffee's flavors more accurately. This is especially true for the highly concentrated espresso, where lingering volatile compounds in the mouth can interfere with the taste buds and retronasal olfactory judgment. Drinking ice water beforehand can effectively enhance flavor perception. This article will provide an in-depth analysis of the mechanism by which ice water functions in coffee tasting, and how this small gesture can help you experience the aroma and layers of the coffee itself more fully.

In coffee flavor descriptions, "tea-like" is a concept widely used in China yet constantly debated. Some people understand it as the aroma of a certain kind of tea, some think it is simply the astringency that returns in the mouth, and still others categorize it as a lingering finish reminiscent of tea broth. This article begins with the bitterness and astringency of tea, then sorts through the causes of sweetness returning and saliva being produced, and next draws on the principle of retronasal olfaction to explain why coffee can bring out a tea-like quality, while also clarifying that tea-like and astringent are not equivalent. The article also combines tasting examples from several Front Street Coffee beans to show that the very same "tea-like" quality may be defined very differently in each person's mind. [more…]

At the same time, for light-roasted coffee beans, it provides a reference brewing parameter scheme, including key points such as coffee dose, coffee-to-water ratio, water temperature, grind size, and extraction time. Combined with the example of Front Street Coffee Yirgacheffe Gutingding, it helps readers understand how to improve coffee flavor by adjusting parameters. [more…]

Many people use "sweet aftertaste" to describe the pleasant mouthfeel of a good cup of coffee, but how exactly does sweet aftertaste differ from sweetness? The aroma, flavor, and mouthfeel that linger in the mouth after swallowing are what we call the finish, and sweet aftertaste is precisely a bitter-then-sweet taste bud experience within that finish. The degree of roast has a significant impact on sweet aftertaste: lightly roasted beans are bright and acidic yet have a short finish, while dark roasted beans are rich and full-bodied with a more lasting sweet aftertaste. This article will guide you through understanding the relationship between sweet aftertaste and the finish, and recommend four coffees with pronounced sweet aftertaste—Front Street PWN Golden Mandheling, Front Street Brazil Queen's Manor, Front Street PNG Bird of Paradise, and Front Street Jamaica Blue Mountain No. 1—analyzing their flavor layers and sources of sweetness one by one.

When drinking coffee, a numb tongue and dry mouth—this rough tactile sensation is astringency. Astringency is not a taste but a tactile feedback caused by friction between the coffee liquid and the oral cavity. Its root lies in the excessive release of polyphenolic compounds in coffee beans—especially chlorogenic acid—which bind with salivary proteins and weaken lubrication. Astringency often interweaves with acidity and bitterness, forming sour-astringent or bitter-astringent notes. This article will begin with the causes of astringency, explain its relationship with extraction state, analyze which astringency counts as a quality characteristic, as well as the astringency that green beans themselves may bring, and offer specific ideas for improvement by adjusting extraction efficiency.

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…]

Buffalo milk has long been a specialty dairy product in the Guangdong and Guangxi regions, and in recent years it has been increasingly used by coffee enthusiasts to pair with espresso.
