After oxidation develops Ceylon tea's distinctive character, two critical final processes at Panilkanda Tea determine the quality and grade of every tea leaf that reaches your cup: precision drying and meticulous sorting. These final manufacturing stages transform oxidized leaves into the premium Ceylon tea grades that have earned international recognition.
The Art of Tea Drying (Firing)
Stopping Oxidation at the Perfect Moment
Once oxidized leaves reach optimal flavor development, our expert tea makers must act swiftly. The process of firing removes most of the leaf moisture and stops fermentation by destroying the enzymes. This crucial timing prevents over-oxidation that would diminish quality.
The Science of Heat Application
When the right amount of aeration has occurred, the leaf is dried in a desiccator or 'firing chamber' at 99-104˚C (210-220˚F) to prevent further chemical changes.
Temperature Control: Our firing chambers maintain precise temperatures to ensure:
- Complete enzyme deactivation without burning the leaves
- Optimal moisture removal reducing content to about 3%
- Flavor balance enhancement as some lesser desirable compounds are removed
- Color development creating the characteristic black tea appearance
The Firing Process at Panilkanda
Advanced Drying Systems: The firing takes place in a specially adapted Tea Drier machine which, at low temperature, removes all surface moisture from the leaf, rendering it suitable for the sifting and grading processes that lie ahead.
Our modern drying equipment ensures:
Controlled Airflow: Hot air circulation removes moisture evenly across all leaves Temperature Monitoring: Digital systems maintain optimal heat levels throughout the process
Quality Preservation: Low-temperature drying protects delicate flavor compounds Consistent Results: Automated systems ensure every batch meets our standards
Chemical Transformations During Firing
Heat inactivates the polyphenol enzymes and dries the leaf to a moisture content of about 3 percent. It also caramelizes sugars, thereby adding flavours to the finished product, and imparts the black colour associated with fermented tea.
Flavor Enhancement: The firing process:
- Caramelizes natural sugars adding sweetness and complexity
- Concentrates essential oils intensifying aroma
- Stabilizes flavor compounds ensuring consistent taste
- Creates final color producing the rich black appearance
The Precision Art of Tea Sorting
Why Sorting Matters
Once the frying and drying process is completed, the tea leaves are moved through different meshes that separate them based on the size, allowing them to be sorted into different grades of tea such as Dust, Pekoe, BOP and more.
After drying, tea consists of various-sized leaf particles that must be separated for successful brewing, since different-sized particles brew at different rates.
The Mechanical Sorting Process
The tea is conveyed direct from the dryer to be sifted and graded. Tea particles are separated according to shape and size by being passed through a series of progressively finer meshes.
Our Sorting Technology:
- Graduated mesh systems with progressively smaller openings
- Vibrating screens that efficiently separate leaf sizes
- Quality control stations monitoring each grade
- Digital tracking ensuring accurate categorization
Understanding Ceylon Tea Grades
The Orange Pekoe System
In the tea industry, tea leaf grading is the process of evaluating products based on the quality and condition of the tea leaves themselves. The highest grades for Western and South Asian teas are referred to as "orange pekoe" (abbreviated as "OP"), and the lowest as "fannings" or "dust".
Important Note: Even though you will see 'Orange' use quite a bit whenever peering into a black tea selection, it does not mean that there is any orange in the tea, and also does not pertain to the color of liquor. The term comes from the House of Orange, the Dutch royal family.
Whole Leaf Grades (Premium Quality)
OP (Orange Pekoe): This grade is the highest grade given to manufactured tea. The characteristics of the tea leaf appear long, wiry and thin. When brewed its flavor has a delicate fragrance and tastes wonderfully delicious and the liquors are light and pale in color.
OP1 (Orange Pekoe 1): The leaf of this grade is delicate, long and wiry. It contains a light liquor and a flavor of refined taste.
FOP (Flowery Orange Pekoe): High-quality tea with long leaves and few tips, containing the finest buds for enhanced flavor complexity.
Broken Leaf Grades (Popular Choice)
BOP (Broken Orange Pekoe): This grade of tea is the most sought after. It is a well made, neat leaf of a medium size with and abundance of stalk and fiber. The flavor of the tea is rich and fresh and the liquor is bright in color.
BOPF (Broken Orange Pekoe Fannings): This grade consists of a leaf that is rather smaller than BOP, it is also one of the most common grades found in Sri Lanka. The leaf is neat and fairly clear and has a richness to its flavor along with a liquor that is bright in color.
Small Particle Grades (Commercial Use)
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.
Dust: These are rather smaller than BOPF, they are fine granular particles that contains optimum strength and body, it is ideal for commercial brewing.
Quality Control Through Expert Assessment
The Master Tea Taster's Role
The made tea is then tasted and assessed by the Teamaker and expert tasters, to ensure it meets all quality standards in terms of leaf appearance, aroma, cup colour and character of the tea.
Assessment Criteria:
- Leaf Appearance: Visual evaluation of size, color, and uniformity
- Dry Aroma: Fragrance intensity and character assessment
- Liquor Color: Brightness and clarity of brewed tea
- Taste Profile: Flavor balance, strength, and distinctiveness
