An Analysis of Why Yinghong No. 9 Tea Turns Cloudy After Cooling: The "Cold Cloudiness" Phenomenon and Its Connection to High-Quality Black Tea

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.

Brewing Yinghong No. 9: Gaiwan or Yixing Teapot? A Comprehensive Comparison from Material and Pouring to Heat Retention

When brewing Yinghong No. 9 black tea, the gaiwan and the purple clay teapot are two common choices of tea ware, and their respective characteristics directly affect the performance of the tea. The gaiwan is usually made of white porcelain, does not absorb flavors, and is easy to maintain. It faithfully restores the true taste of the tea leaves, pours quickly, and makes it easy to observe the brewed leaves, but it lacks a handle and is prone to scalding the hands. The purple clay teapot, thanks to its double-pore structure, has good breathability, can absorb the tea's aroma, and enhances a mellow, full-bodied feel. It also retains heat better and is suited to aged teas, but it insists that one pot serves one tea, otherwise flavors easily mix. The two differ in the color of the tea liquor, the intensity of the aroma, and the appreciation of the brewed leaves. Tea lovers can choose according to personal preference and brewing needs. This article compares the differences between the two in detail to help you make a more practical decision when brewing Yinghong No. 9. [more…]

Brewing Yingde Yinghong No.9 Black Tea: A Full Analysis of Flavor Layers Across Seven Infusions, from Fruity Sweetness to Roasted Notes

Yinghong No.9 comes from Yingde, Guangdong, and is named after an experimental cultivar. The dry leaves are tightly rolled with visible golden buds, carrying forest-floor earthiness and a roasted aroma. In this session it was brewed gongfu style, using 3g of tea with 150ml of boiling water, a 45-second first infusion, and an extra 15 seconds for each subsequent infusion, for five to seven consecutive steeps. Front Street Coffee recommends brewing it in a gaiwan, which better reveals its complete progression from sweet, fruity notes to woody roast. From the first infusion's deep amber color, musky earthiness, and sweet plum flavors to the seventh infusion's roast and astringency, each steep delivers a different experience. This tea suits lovers of earthy, fruity, or roasted black teas, and is especially good for savoring on a winter afternoon. [more…]

Heytea's Yinghong Cheese Sticky Rice launch immediately drew criticism: consumers report insomnia and palpitations, and the lack of caffeine labeling raises questions.

Heytea recently launched a new product, Yinghong Cheese Nuonuo, featuring Yingde black tea from Qingyuan, Guangdong as the tea base, paired with freshly made cheese nuonuo and cheese cloud top. Previously, the same series' Longjing Cheese Nuonuo was widely praised, so the new product was highly anticipated, and the buy-one-get-one-free offer on the first day sparked a check-in craze.

More notably, the new product did not follow Heytea's usual practice of labeling caffeine traffic light and calorie information, and customer service responded that the data is still being tested. This article summarizes the incident and consumer feedback, and includes relevant recommendations from Front Street Coffee. [more…]

From Lapsang Souchong to CTC Broken Black Tea: A Full Analysis of the Craft and Quality Differences Among the Three Major Black Tea Categories

The world of black tea is far richer than one might imagine. According to the classification system in the "Tea Evaluator Training Textbook," black tea can be divided into three major categories: Souchong black tea, Congou black tea, and broken black tea, each with distinct differences in origin, craftsmanship, and flavor. Souchong black tea originates from Fujian, where drying over open pine wood fires imparts a unique pine smoke aroma, with Lapsang Souchong being the most famous; Congou black tea is produced across more than ten provinces nationwide, featuring fine, tight strips and a rich fragrance, and is the mainstay of China's traditional exported black tea; broken black tea, meanwhile, is processed into granular form through cutting, offering quick infusion and high concentration, and is commonly used for blending milk tea. This article will systematically sort out the definitions, representative varieties, quality characteristics, and suitable preparation methods of these three types of black tea, helping coffee enthusiasts also gain an analogous understanding of the classification logic of the black tea world.

Starbucks System Glitch Triggers Rush for Two Cups for 9 Yuan, 49.9 Yuan Women's Day Promotion Accidentally Leaks Low-Price Loophole

After Luckin Coffee's 9.9 yuan promotion was scaled back, brands like Cotti Coffee and Tims rolled out short-term 9.9 yuan offers to grab market share.
