Whole Leaf vs Broken Leaf vs Fannings vs Dust: What’s the Difference?

Not all tea leaves are sized equally. The size and form of the leaf play a major role in how tea tastes, brews, and behaves in the cup. Leaf grade refers to the leaf size and how much the leaf has been broken during processing.

Whole leaf tea consists of intact or largely unbroken leaves. They require more careful plucking and handling and are typically produced in smaller quantities. These leaves infuse slowly, releasing flavour in layers. Whole leaf teas tend to have greater aroma, complexity, and clarity, and can often be re-steeped multiple times. 

Broken leaf tea contains leaves that have been intentionally or mechanically broken during processing. These teas brew faster and produce a stronger cup, but with less nuance than whole leaf tea.

Fannings are smaller fragments of tea left after larger leaves are sorted out. They infuse very quickly and while they deliver colour and strength, they lack depth and subtlety. 

Dust refers to the finest particles of tea, almost powder-like in texture. As smaller particles expose more surface area to water, they brew almost instantly, leading to faster extraction, producing a dark, often bitter cup with little aroma. It is typically used for mass-market tea bags. 

Both Dust and Fannings are more efficient to manufacture and are therefore more common in large-scale production.

The difference between these grades is not just about appearance, but about how flavour is released. Understanding leaf grade helps buyers make better choices.
