D (Dust, CTC Black Tea)

1. Definition and Process D is the finest‑granule grade of CTC black tea, fine tea dust obtained from multi‑stage screening during production. Produced by withering, CTC crushing‑tearing‑curling, fermentation, screening and drying. With ultra‑fine powder, it infuses fastest and releases large amount of colour substances within short time. Mainly applied for low‑cost tea‑bags and milk‑tea blending for colour enhancement.

2. Raw Material and Characteristics

  • Raw Material: Mostly screen by‑products from mature tea leaves, lowest tenderness among CTC grades.
  • Appearance: Ultra‑fine dark‑brown‑black powder, barely any golden tips, high content of fine stems and tea dust. It has the smallest particle size in CTC range.
  • Internal Quality: Very deep reddish‑brown liquor with poor clarity.

3. Functional/Quality Characteristics

  • Aroma: Mainly caramel and roasted notes, coarse and short aroma, almost no brisk floral notes.
  • Taste: Heavy‑bodied liquor with strong astringency and bitterness. It colours liquor within seconds; even short over‑steeping brings heavy bitterness. It produces very dark colour with milk but thin and flat flavour with little complexity.
  • Nutrition: Contains theaflavins and thearubigins, yet overall flavour quality ranks lowest among CTC grades.

4. Application Scenarios ‑ Ultra‑cost‑effective raw material for economy‑grade tea‑bags for fast colour extraction. ‑ Blending component to boost liquor colour and reduce overall material cost. ‑ Not suitable for loose brewing; fine powder passes through filters. Only for sealed tea‑sachets, for milk‑based drinking only, not for straight consumption.

5. Brewing Suggestions‑Water Temperature: 85‑95°C ‑ Time: 0.5‑1 minute. Very short infusion is required to avoid heavy bitterness. ‑ Tea Set: Tea sachet only, normal filters cannot hold ultra‑fine dust.

In summary, D grade CTC is ultra‑fine tea dust with powerful colouring capacity and cost advantage. It is used for low‑end tea‑bags and colour‑oriented blending, not for premium flavour pursuit。
