? 1. What is Green Tea PS (Pekoe Souchong)?

PS (Pekoe Souchong) is a leaf grade classification in the orthodox tea grading system.

✔️ Technical Definition:

  • Leaf Grade: Broken leaf tea
  • Position in grading scale:
    Whole leaf (OP) → Broken leaf (BOP / PS) → Fannings → Dust

? PS is typically:

  • Larger than fannings
  • Smaller than OP (Orange Pekoe)
  • Irregular broken leaf particles

⚙️ 2. Physical & Sensory Characteristics

? Dry Leaf (Appearance)

  • Medium-size broken leaf
  • Dark green to olive green color
  • Slight twist, non-uniform particles

? Liquor (Infusion)

  • Color: Yellow-green to light amber
  • Aroma: Fresh, grassy, slightly vegetal
  • Taste: Mild astringency, medium body

? Faster extraction compared to whole leaf grades

? 3. Standard Export Specifications (Typical Range)

Parameter Specification
Moisture Content ≤ 7.0%
Foreign Matter (FM) ≤ 0.5%
Broken Ratio ≥ 85–90%
Dust Content ≤ 5%
Color Natural green
Infusion Clear, no turbidity
Mold / Insects Absent
Odor Free from off-odor

? Compliant with ISO 3720 (tea standard reference) and general export requirements.

? 4. Processing Method (Orthodox Green Tea)

Green Tea PS is produced using orthodox processing, including:

  1. Plucking – Young tea leaves harvested
  2. Fixation (Kill-green) – Enzyme deactivation via heat
  3. Rolling – Leaf shaping and cell breakage
  4. Drying – Final moisture reduction to ≤7%
  5. Sorting & Grading – Separation into PS grade

? Final grading determines particle size distribution

? 5. Industrial Applications (B2B Focus)

Green Tea PS is widely used in:

✔️ Tea Bag Production

  • Fast infusion
  • High extraction efficiency

✔️ RTD (Ready-to-Drink) Tea

  • Stable flavor
  • Easy large-scale processing

✔️ Blending & Flavoring

  • Base tea for jasmine, fruit, herbal blends

✔️ Food & Beverage Manufacturing

  • Tea extracts
  • Functional drinks

 

? 6. Why Importers Choose PS Grade

✔ Cost-effective vs whole leaf tea
✔ High extraction yield
✔ Consistent particle size for automation
✔ Stable bulk supply

? Ideal for industrial-scale production

⚠️ 7. Critical Quality Control Factors

Professional buyers evaluate beyond basic specs:

? Microbiological Safety

  • Total Plate Count (TPC)
  • Yeast & Mold

? Chemical Compliance

  • Pesticide residues (EU MRL compliance)
  • Heavy metals (Pb, Cd limits)

? Shelf Stability

  • Moisture ≤7%
  • Water activity (aw) control

? 8. Packaging & Export Logistics

  • 25kg / 50kg PP or kraft bags
  • Optional: aluminum liner / vacuum packaging
  • Container: 20FT / 40FT
  • Storage: dry, ventilated, no contamination
