Frequently Asked Questions
What water temperature should I use for each tea?
Green and white teas do best around 175°F, oolong near 195°F, and black, pu-erh, and herbal teas close to boiling. Cooler water keeps delicate teas from turning bitter.
How long should I steep tea?
Typical ranges are 2 to 3 minutes for green, 3 to 5 for black and oolong, and 5 to 7 for herbal tisanes. Over-steeping mainly adds bitterness.
How much caffeine is in a cup of tea?
It varies by type and brewing, but per 8-ounce cup black tea has roughly 47 mg, green about 28 mg, and herbal tea none. These are general estimates only.
Is the caffeine estimate medical advice?
No. Caffeine content depends on leaf amount and steep time, so figures are approximate. This is general information only and is not medical advice; consult your doctor if you are sensitive to caffeine.
