What happens
Makers alternate increasingly assertive agitation with controlled rest, reading leaf softness, edge color and aroma. Basket shaking, hand tossing and mechanical drums are all used in different traditions.
What it changes in the cup
The process can generate orchids, gardenia, ripe fruit, honey and complex green-to-roasted transitions. Poor control may leave grassy, sour, thin or muddled aroma.
How to observe it
Inspect an opened leaf for softened texture and reddish edges, then follow how aroma changes across infusions. Edge color alone is not a complete quality score.

Identification and caution
Oolong is not defined by one oxidation level. Agitation, cultivar, shaping and roast combine to create many oolong styles.
