What happens
Leaves may be rolled by hand, basket, cloth bag or machine. Pressure and time range from gentle shaping that preserves whole leaf to strong rolling that releases juice and supports rapid black-tea oxidation.
What it changes in the cup
Stronger rolling generally increases extraction speed and can build body, color and intensity. Excessive force may produce broken leaf, harshness or loss of aromatic delicacy.
How to observe it
Compare dry shape with the opened leaf. A tightly rolled tea may need a rinse or slightly longer first infusion, then extract rapidly after the leaf opens.
Practical guidance

Identification and caution
Hand rolling is not automatically superior to machine rolling. The relevant question is whether the method fits the tea and is controlled consistently.
