How much caffeine does tea contain?

The amount of caffeine in a cup of tea is determined by how you are brewing your tea. If brewed properly at the right temperature and for the correct amount of time, the caffeine content will vary by the type of tea you are brewing.  Use the chart below as an estimated guideline.

TEA (loose, 8 oz)

Black

45-60 mg

Oolong 20-50 mg
Green 10-25 mg
White 6-20 mg
Rooibos

0 mg

Herbal (Tisane)

0 mg

OTHER

Hot Cocoa (6 oz) 10-14 mg
Coca-Cola (12 oz) 35-45 mg
Pepsi-Cola (12 oz) 36-38 mg

COFFEE (8 oz)

Drip

175-210 mg

Decaf 2-12 mg
Instant 27-173 mg

Too much caffeine can cause:  rapid heartbeat, irritability, insomnia, indigestion, nervousness, and dizziness.  Health experts agree that 400 450 mg of total caffeine intake from all sources (coffee, soda, chocolate, tea and others) per day is safe for adults and children older than 12.  To eliminate caffeine intake completely, please consider switching to herbal tea, because even decaffeinated tea and coffee contain a trace (between 5 and 10 milligrams) of caffeine.
