The Black Tea Grading Guide: What Do OP, FOP, and BOP Mean?

If you have ever purchased loose-leaf black tea, you have probably encountered abbreviations such as FOP, OP, Pekoe, BFOP, BOP, BOPF, Fannings, or Dust.

For many tea drinkers, these codes can seem confusing. Some assume they indicate quality, while others believe they describe flavor.

In reality, black tea grades help describe two important characteristics:

• The maturity of the leaf material harvested from the tea shoot.
• The size of the finished tea after grading and sorting.

Understanding these grades helps tea buyers, tea enthusiasts, and tea professionals choose the right tea for their preferred brewing style and flavor profile.

It is important to remember that tea grades do not automatically determine quality. A well-made BOP can outperform a poorly manufactured FOP. Cultivar, terroir, harvest season, and processing expertise remain equally important.

Understanding the Tea Shoot

Traditionally, whole-leaf black tea grades are associated with different positions on the tea shoot.

As leaves mature and grow larger further down the stem, they are classified into different grades.

The traditional hierarchy generally progresses as follows:

• FOP (Flowery Orange Pekoe): one bud and two young leaves
• OP (Orange Pekoe): the first and second young leaves after the bud opens
• P (Pekoe): traditionally associated with the third leaf
• PS (Pekoe Souchong): traditionally associated with the fourth leaf
• S (Souchong): traditionally associated with the fifth leaf

In general, younger leaves produce more delicate aromas and refined flavors, while mature leaves contribute greater body and strength.

FOP (Flowery Orange Pekoe)

FOP stands for Flowery Orange Pekoe.

Traditionally, FOP is harvested using the fine-plucking standard of one bud and two young leaves.

The name can be broken down as follows:

• Flowery refers to the presence of young leaf tips.
• Orange is a historical tea-trade term and has nothing to do with oranges or citrus flavor.
• Pekoe refers to fine young tea leaves.

Because the bud remains intact during harvest, FOP teas often contain visible tips that may develop a golden appearance during oxidation.

These golden tips are highly valued and often contribute to the tea’s attractive appearance.

FOP teas are commonly prized for:

• Elegant appearance
• Delicate aroma
• Refined flavor
• Premium loose-leaf presentation

Why Many People Mistakenly Think FOP Is “Tips Only” or “One Bud and One Leaf”

One of the most common misconceptions in tea is that FOP consists of only a bud, or a bud and a single young leaf.

Traditionally, FOP is harvested as one bud and two young leaves.

So why does FOP often appear to contain only a bud and one leaf?

The answer lies in processing.

The first young leaf immediately beneath the bud is extremely small and delicate. During rolling, it often twists tightly around the bud. During drying, it shrinks significantly as moisture is removed.

As a result, when consumers inspect the finished tea, the smallest leaf can become almost invisible. What remains visually obvious is the bud and the larger second leaf.

This creates the illusion that FOP consists of only a bud and one leaf, even though the original plucking standard remains one bud and two young leaves.

Another source of confusion comes from ultra-premium tip-heavy grades.

When a tea contains an exceptionally high concentration of buds and golden tips, it may be classified into higher tip grades rather than standard FOP.

GFOP (Golden Flowery Orange Pekoe)

GFOP contains a greater proportion of golden tips than standard FOP. The additional tips often contribute to a more elegant appearance and refined aroma.

TGFOP (Tippy Golden Flowery Orange Pekoe)

The word Tippy indicates an even higher concentration of young buds and golden tips. These teas are generally more selective than standard GFOP.

FTGFOP (Fine Tippy Golden Flowery Orange Pekoe)

The addition of Fine indicates a more carefully selected and refined grade with excellent leaf appearance, abundant tip content, and superior manufacturing standards.

SFTGFOP (Special Fine Tippy Golden Flowery Orange Pekoe)

SFTGFOP represents one of the most prestigious orthodox black tea grades. These teas contain exceptional tip content, highly selective leaf material, and careful manufacturing.

The progression generally follows:

FOP → GFOP → TGFOP → FTGFOP → SFTGFOP

As the concentration of buds and golden tips increases, the tea moves into increasingly premium classifications.

OP (Orange Pekoe)

OP stands for Orange Pekoe.

Traditionally, OP is associated with the first and second young leaves after the terminal bud has already opened.

Many tea drinkers assume OP contains fewer leaves than FOP. In reality, the difference is not the number of leaves but the stage of growth.

When a tea shoot remains on the bush for a few additional days, the terminal bud opens and develops into a leaf. The young leaves beneath it continue growing and become larger.

As a result, OP leaves are often:

• Larger than FOP leaves
• Longer and more twisted after rolling
• Lower in visible tip content
• Slightly fuller in body

OP is widely regarded as one of the benchmark grades for orthodox black tea.

P (Pekoe)

P stands for Pekoe.

Traditionally, Pekoe is associated with the third leaf on the tea shoot.

Compared with OP, Pekoe leaves are broader, slightly more mature, and generally produce a stronger cup.

Pekoe teas are often characterized by:

• Fuller body
• Stronger infusion
• Darker liquor
• Less delicate aroma

In commercial production, Pekoe grades may also contain smaller pieces of younger leaves that naturally sort into the same size category during grading.

PS (Pekoe Souchong)

PS stands for Pekoe Souchong.

Traditionally, Pekoe Souchong is associated with the fourth leaf on the tea shoot.

These leaves are larger, coarser, and more mature than Pekoe leaves.

Because of their maturity, Pekoe Souchong teas often deliver:

• Strong body
• Deep color
• Robust flavor
• Powerful extraction

PS grades are frequently chosen when a stronger and bolder cup is desired.

S (Souchong)

S stands for Souchong.

Traditionally, Souchong is associated with the fifth leaf on the tea shoot.

Compared with younger grades, Souchong generally produces a stronger, fuller-bodied cup with less aromatic delicacy than FOP, OP, or Pekoe grades.

Characteristics often include:

• Strong body
• Robust character
• Deep liquor color
• Bold flavor

The term is also widely associated with smoked black teas such as Lapsang Souchong.

Understanding Broken Tea Grades

After manufacturing and sorting, not all leaves remain intact.

Some leaves naturally break during rolling, handling, and grading. These broken leaves are classified separately.

BFOP (Broken Flowery Orange Pekoe)

BFOP stands for Broken Flowery Orange Pekoe.

BFOP consists of broken leaf particles originating from FOP-grade material.

Because some tip content may still be present, BFOP often retains more aroma and complexity than many standard broken grades.

Characteristics typically include:

• Good aroma
• Faster extraction than FOP
• Balanced body
• Some visible tip content
• Stronger brew than whole-leaf FOP

BFOP can be thought of as the broken-leaf counterpart of FOP.

BOP (Broken Orange Pekoe)

BOP stands for Broken Orange Pekoe.

BOP consists of broken leaf particles that would otherwise qualify as Orange Pekoe.

Compared with OP, BOP typically produces:

• Faster extraction
• Stronger liquor
• Fuller body
• Shorter brewing time

Because of its consistency and strength, BOP is one of the most widely traded black tea grades in the world.

BOPF (Broken Orange Pekoe Fannings)

BOPF stands for Broken Orange Pekoe Fannings.

BOPF is smaller than BOP and sits between broken leaf tea and fannings.

A simple way to understand the progression is:

• OP = whole leaf
• BOP = broken OP
• BOPF = smaller broken OP

Because of its smaller particle size, BOPF delivers:

• Very fast extraction
• Strong color
• Strong body
• Excellent performance in milk tea

Many tea shops and foodservice operators prefer BOPF because it consistently produces a strong cup in a short time.

Fannings

Fannings are small tea particles separated during grading.

Although commonly associated with tea bags, fannings are not waste material.

Their small size allows them to infuse quickly and efficiently.

Characteristics often include:

• Fast extraction
• Strong liquor
• Pronounced astringency
• Consistent brewing performance

Fannings are widely used in commercial tea bag production.

Dust

Dust is the finest tea particle grade.

Despite the name, Dust is not a waste product. It is simply the smallest particle size produced during sorting.

Dust is valued because it provides:

• Fastest extraction
• Strongest color
• Strongest body
• Near-instant brewing performance

Many commercial tea bags rely on Dust because it produces a strong cup quickly and consistently.

Why Leaf Size Changes the Cup

One of the most important concepts in tea is surface area.

Whole leaves expose relatively little surface area to water and release flavor compounds slowly.

Smaller particles expose significantly more surface area, allowing caffeine, polyphenols, and flavor compounds to extract more rapidly.

As particle size decreases:

• Brewing speed increases
• Body becomes stronger
• Color becomes darker
• Astringency becomes more pronounced

This is why whole-leaf teas are often preferred for leisurely tea sessions, while BOPF, fannings, and dust are commonly chosen for milk tea, breakfast tea, and tea bags.

Which Grade Should You Choose?

If you enjoy premium loose-leaf tea with delicate aromas and visible golden tips, FOP and higher tip grades are often the best choice.

If you prefer balanced everyday black tea with good body and consistency, OP and Pekoe grades are excellent options.

If you enjoy stronger tea, milk tea, or breakfast tea, BOP and BOPF are often preferred because they brew quickly and produce a fuller-bodied cup.

For tea bags and quick preparation, fannings and dust provide strength, speed, and consistency.

Final Thoughts

Black tea grading can seem complicated at first, but the system becomes much easier to understand once you separate two concepts: leaf maturity and particle size.

FOP, OP, Pekoe, Pekoe Souchong, and Souchong traditionally describe different positions on the tea shoot, while BFOP, BOP, BOPF, fannings, and dust describe progressively smaller particle sizes created during grading.

Understanding these classifications allows tea buyers, tea enthusiasts, and tea professionals to make more informed decisions and select the tea best suited to their preferred brewing style, flavor profile, and application.
