Dust (D) is a grade of black tea that consists of the smallest particles in the tea leaf classification system. While other grades, such as Orange Pekoe or Broken Orange Pekoe, include larger leaves or broken pieces, dust represents the finest, smallest tea particles, which are typically the result of the mechanical processing and sifting of larger leaves. Despite its smaller size, dust tea can offer a strong and bold flavor.

Key Characteristics of Dust (D) Tea:

1. Grade Type:

   • Dust tea consists of the smallest particles, often the result of the processing and sifting of larger leaves, and is classified as the lowest grade in the leaf grading system.
   • It is usually made from broken leaves that are finer in size and may consist of very small, powder-like particles.

2. Leaf Appearance:

   • The appearance of dust tea is very different from that of whole or broken leaves. Dust tea looks like tiny, powdery particles that may be dark brown or black in color.
   • These fine particles do not resemble whole or broken leaves, making them less visually appealing, but their small size makes for a quicker infusion and stronger brew.

3. Flavor Profile:

   • Dust tea is known for its strong, bold, and brisk flavor. Because of the fine particle size, the tea brews quickly and releases its flavor more intensely compared to larger leaf grades.
   • The flavor is often robust and full-bodied, but it can also be somewhat astringent or bitter if over-brewed.
   • Due to its high concentration of smaller particles, dust tea tends to lack the complexity and nuance found in higher grades like FBOP or OP. However, it can have a strong malty, spicy, or musky flavor, depending on the origin.

4. Brewing & Usage:

   • Dust tea is most commonly used in tea bags because of its small size. The small particles allow for a quick brew and produce a strong infusion in a short amount of time.
   • It’s ideal for those who enjoy strong, quick-brewing tea, especially when mixed with milk and sugar, as it creates a rich, bold cup.
   • Dust tea is less commonly brewed loose-leaf, but it is often used for mass-market tea bags and is popular in blends due to its strength.

5. Production Regions:

   • Dust tea is produced in the same regions as other black teas, including India, Sri Lanka, Kenya, and China.
   • It is particularly common in India (especially Assam) and Sri Lanka (Ceylon), where it is often used in strong breakfast teas or blends.
   • Kenya is another major producer of dust tea, which is commonly found in Kenyan blends.
