How the number behaves

Brewed tea has no single true number: leaf amount, water temperature, and steep time all move it, so the 28mg figure is a compiled average for a standard 8 oz cup rather than a label guarantee. brewed white tea brewed strong with more leaf lands higher; a short, cooler steep lands lower.

The mistake people make is treating every cup as identical. The same leaves steeped five minutes instead of two can carry meaningfully more caffeine, so treat 28mg as the midpoint of a range, not a fixed dose.
