Tea leaf grading
Evaluation of quality and condition of tea leaves

Tea leaf grading evaluates the quality and condition of tea leaves and is essential in the tea industry. The highest Western and South Asian grades are "orange pekoe" (OP), with variations such as CTC teas having distinct grading systems. Top-quality pekoe consists mainly of young leaf buds picked carefully by hand to avoid damage. Lower grades like fannings and dust are smaller remnants formed during processing and often used in bagged teas labeled as "broken" (e.g., "broken orange pekoe" or BOP). Additionally, OP grades have subcategories such as "TGFOP1" (Tippy Golden Flowery Orange Pekoe, First Grade), which denote superior leaf size and wholeness. Different tea varieties, like white tea, typically use specific leaf grades suited to their processing methods.

General classifications

Grading by size

Although grading systems vary, the size of the leaf or broken pieces is an essential quality. Size is an important factor how tea is prepared as a beverage. In general, larger leaves or pieces require a longer steeping time. Also, if measured by volume, the larger sizes need more tea to produce the same strength beverage.4

Grading by appearance

Some teas are graded by their appearance. Whole leaves are easier to grade by appearance than broken pieces.5

Orange pekoe

Orange pekoe (/ˈpɛkoʊ, ˈpiːkoʊ/), also spelled pecco, or OP is a term used in the Western tea trade to describe a particular genre of black teas (orange pekoe grading).67 Despite a purported Chinese origin, these grading terms are typically used for teas from Sri Lanka, India and countries other than China; they are not generally known within Chinese-speaking countries. The grading system is based upon the size of processed and dried black tea leaves.

The tea industry uses the term orange pekoe to describe a basic, medium-grade black tea consisting of many whole tea leaves of a specific size;8 however, it is popular in some regions (such as North America) to use the term as a description of any generic black tea (though it is often described to the consumer as a specific variety of black tea).910 Within this system, the teas that receive the highest grades are obtained from new flushes (pickings).11 This includes the terminal leaf bud along with a few of the youngest leaves. Grading is based on the "size" of the individual leaves and flushes, which is determined by their ability to fall through the screens of special meshes12 ranging from 8–30 mesh.13 This also determines the "wholeness", or level of breakage, of each leaf, which is also part of the grading system. Although these are not the only factors used to determine quality, the size and wholeness of the leaves will have the greatest influence on the taste, clarity, and brewing time of the tea.14

When used outside the context of black-tea grading, the term "pekoe" (or, occasionally, orange pekoe) describes the unopened terminal leaf bud (tips) in tea flushes. As such, the phrases "a bud and a leaf" or "a bud and two leaves" are used to describe the "leafiness" of a flush; they are also used interchangeably with pekoe and a leaf or pekoe and two leaves.15

Etymology

The origin of the word "pekoe" is uncertain. One explanation is that it is derived from the transliterated mispronunciation of the Amoy (Xiamen) dialect word for a Chinese tea known as "white down/hair" (白毫; Pe̍h-ōe-jī: pe̍h-ho).16 This is how "pekoe" is listed by Rev. Robert Morrison (1782–1834) in his Chinese dictionary (1819) as one of the seven sorts of black tea "commonly known by Europeans".17 This refers to the down-like white "hairs" on the leaf and also to the youngest leaf buds. Another hypothesis is that the term derives from the Chinese báihuā "white flower" (Chinese: 白花; pinyin: báihuā; Pe̍h-ōe-jī: pe̍h-hoe), and refers to the bud content of pekoe tea.

Sir Thomas Lipton, the 19th-century British tea magnate, is widely credited with popularizing, if not inventing, the term "orange pekoe", which seems to have no Chinese precedent, for Western markets. The "orange" in orange pekoe is sometimes mistaken to mean the tea has been flavoured with orange, orange oils, or is otherwise associated with oranges. However, the orange fruit is unrelated to the tea's flavor.18 There are two explanations for its meaning, though neither is definitive:

  1. The Dutch House of Orange-Nassau, now the royal family, was already the most respected aristocratic family in the days of the Dutch Republic and came to control the de facto head of state position (Stadtholder) of Holland and Zealand. The Dutch East India Company played a central role in bringing tea to Europe and may have marketed the tea as "orange" to suggest association with the House of Orange.19
  2. Colour: the copper colour of a high-quality, oxidized leaf before drying, or the final bright orange colour of the dried pekoes in the finished tea may be related to the name.20 These usually consist of one leaf bud and two leaves covered in fine, downy hair. The orange colour appears when the tea is fully oxidized.

Fannings

Fannings are small pieces of tea that are left over after higher grades of teas are gathered to be sold. Traditionally these were treated as the rejects of the manufacturing process in making high-quality leaf tea like the orange pekoe. Fannings with extremely small particles are graded "Dust" (See "Dust grades" below).21 Fannings and dusts are considered the lowest grades of tea, separated from broken-leaf teas which have larger pieces of the leaves. However, the fannings of expensive teas can still be more expensive and more flavourful than whole leaves of cheaper teas.

This traditionally low-quality tea has, however, experienced a huge demand in the developing world in the last century as the practice of tea drinking became popular. Tea stalls in India and the South Asian sub-continent and Africa prefer dust tea because it is cheap and also produces a very strong brew; consequently, more cups are obtained per measure of tea dust.

Because of the small size of the particles, a tea infuser is typically used to brew fannings.22 Fannings are also typically used in most tea bags, although some companies sell tea bags containing whole-leaf tea.23

Some exporters focus primarily on broken-leaf teas, fannings, and dusts.24

Grades

Choppy contains many leaves of various sizes. Fannings are small particles of tea leaves used almost exclusively in tea bags. Flowery consists of large leaves, typically plucked in the second or third flush with an abundance of tips. Golden flowery includes very young tips or buds (usually golden in colour) that were picked early in the season. Tippy includes an abundance of tips.25
