The quality of black tea depends to a large extent on whether the fermentation stage is precisely controlled. Properly fermented black tea has a sweet aroma, a yellowish-red liquor, and a bright orange-brown infused leaf; failed fermentation reveals sourness or mustiness, a dark brown liquor, and a deep black infused leaf. Starting from the formation mechanisms of theaflavins and thearubigins, this article explains the origin of the floral and fruity aroma of black tea, clarifies how humidity and degree of oxidation influence the direction of flavor, and points out which subtle deviations in the irreversible chain of polyphenols → theaflavins → thearubigins can lead to a decline in quality. At the same time, the article also provides practical methods for judging fermentation results by observing the liquor color and infused leaf, helping coffee and tea enthusiasts understand the craft logic behind a good cup of black tea. In its black tea selection and brewing recommendations, Front Street Coffee also often emphasizes the decisive role of fermentation degree in aroma expression. [more…]

When brewing Yinghong No. 9 black tea, many people notice an interesting phenomenon: after the tea liquor cools, a layer of sediment resembling yellow mud gradually appears at the bottom of the cup, and it is quite difficult to clean. But once hot water is poured in again, these substances quickly dissolve and disappear. Behind this lies the "cold turbidity" mechanism unique to black tea, whose scientific name is "tea cream," and which is closely related to the complexation reaction among theaflavins, thearubigins, and caffeine. Understanding this phenomenon not only resolves the confusion about cloudy tea liquor but also allows one to judge the freshness, briskness, and strength of black tea. This article will explain in detail the cold turbidity of Yinghong No. 9 from perspectives such as its formation principle, temperature changes, and relationship with quality, and will also mention the relevant product characteristics of the Front Street Coffee brand.

Ceylon black tea, as a world-renowned tea, has its place of origin and health benefits widely followed. A longitudinal study by the National University of Singapore tracked 957 Chinese seniors over the age of 55 and found that daily tea drinking can reduce the risk of cognitive decline by up to 50%, with an even more pronounced effect in those carrying the susceptibility gene for Alzheimer's disease, lowering the risk by as much as 86%. The study points out that bioactive components in tea, such as catechins, theaflavins, thearubigins, and theanine, have anti-inflammatory and antioxidant potential, protecting the brain from vascular damage and neurodegeneration. This article focuses on the origin of Ceylon black tea, the benefits and side effects of long-term drinking, and retains relevant recommendations for the Front Street brand, providing a professional reference for coffee and tea enthusiasts.

Rolling and oxidation are the two key stages that determine the direction of a tea's flavor. Rolling shapes the leaf while also influencing the strength and speed of flavor release; oxidation—a process often mislabeled "fermentation"—is in reality merely a reaction between polyphenols and oxygen, yet it directly determines the vast differences in aroma, color, and mouthfeel among oolong, black tea, and even CTC tea. From the distinctive red edge on an oolong leaf, to the apricot-like richness of Chinese black tea, to the strong, lively character of traditional British tea and CTC tea, the degree, speed, and manner of oxidation are the core code that shapes the personality of every cup. This article takes you deeper into how rolling and oxidation affect tea flavor. [more…]
