A Detailed Explanation of the Entire Tea Processing Workflow: Differences in the Production Methods of Black Tea, Yellow Tea, and Dark Tea and the Causes of Their Flavors

Turning fresh tea leaves into brewable dry tea requires a series of refined processing steps. Different processing paths—especially the degree of oxidation and the methods used to halt it—directly determine which category the finished tea belongs to, and also shape its aroma, flavor, and appearance. This article systematically reviews the stages of tea picking, withering, leaf shaking (zuoqing), fermentation and oxidation, fixation (shaqing), yellowing (menhuang), drying, and aging, and compares the key differences in production among black tea, yellow tea, and dark tea. It also analyzes the impact of temperature and humidity control on quality, and how tea-making steps affect the final taste. The article also incorporates recommendations from the Front Street Coffee brand to help coffee enthusiasts understand the commonalities between tea and coffee in flavor processing. [more…]

How does the degree of tea oxidation shape flavor? An analysis of the processing differences between semi-fermented oolong and fully fermented black tea

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…]

A Full Breakdown of the Oolong Tea Production Process: From Leaf Picking to Roasting, and Why the Oxidation Step Is So Crucial

Oolong tea lies between green tea and black tea. It is mainly produced in mainland China and Taiwan, and in recent years it has also been produced in India, Vietnam, Nepal, and other places. Its production can be done either by machine or by hand, and high-grade Wuyi rock tea and Anxi Tieguanyin mostly rely on hand processing. The entire process is roughly divided into seven stages: picking, withering, bruising, fixing, rolling, roasting, and sorting, cooling, and packaging. Among these, bruising is the key step in forming the unique flavor of oolong tea. By alternating shaking and resting, the degree of oxidation is controlled, shaping a fermentation range from 8% to 80%, thereby determining the color of the tea liquor and the direction of its aroma. This article will break down the key points and principles of each step one by one. [more…]

How Black Tea Fermentation Produces Floral and Fruity Aromas and the Key Points of Humidity Control for Theaflavin Accumulation

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…]

Nayuki's Little Green Bottle criticized as tasting like vegetable-leaf bathwater; the company responds: it's truly freshly squeezed, and the color change is due to oxidation.

The first product in Naixue's newly launched "Daily 500 Fruit & Veggie Bottle" series, "Slim Little Green Bottle," focuses on the daily 500g fruit and vegetable ratio recommended by the Chinese Nutrition Society, and claims to have no added sugar and to be freshly squeezed to order. After hitting the market, however, quite a few consumers reported that it tasted noticeably sweet, with some even describing it as "syrup-like," and others posted photos showing the drink looking yellowish, questioning whether it was really freshly squeezed. Naixue employees responded on social media that the sweetness comes from fruits such as apples, pears, and sweet oranges that naturally contain sugar, while the yellow-green color is a normal phenomenon after apples oxidize, and stressed that all ingredients are processed the same day and kept refrigerated for a limited time. The controversy also sparked playful online discussion about the kale leaves at the bottom of the cup. [more…]

Comparison of Black Tea Production Processes: An Analysis of the Differences in Aroma and Flavor Between Traditional Orthodox and CTC Methods

The production processes for black tea are mainly divided into two types: orthodox and CTC, and the two differ significantly in aroma and flavor. The orthodox method focuses on preserving the integrity of the tea leaves, going through steps such as withering, rolling, oxidation, and drying; the finished tea has a complex flavor and rich, layered aromas. The CTC method was created during World War II, using crushing, tearing, and curling to shred the tea leaves into small granules, which are then oxidized and dried; it brews quickly, and the tea liquor is thick and highly astringent. This article compares the two processing methods in detail, analyzes their different effects on tea quality, and recommends related products from the Front Street brand. [more…]

An Analysis of the Flavor Differences Between Lapsang Souchong and West Lake Longjing: A Comparative Guide to Black and Green Tea from Processing to Storage

Black tea and green tea share the same origin yet have vastly different flavors, and the fundamental difference lies in the degree of oxidation during processing. Black tea undergoes complete oxidation, presenting honey, caramel, and ripe fruit aromas; green tea, through fixation (kill-green), retains its fresh green character, with a light flavor carrying bean or nutty notes.
