Caffeine-Sensitive? A Practical Guide to Drinking Ripe Pu-erh
Share
A small cup of ripe pu-erh can turn into four or five refills without much thought. If caffeine tends to keep you awake, start with the whole tea session: how much leaf you use, how many pours you drink, and how close you are to bedtime. Ripe pu-erh contains caffeine, and the amount in the cup varies with how you brew it.

1. Use less leaf and count the refills
Try using a little less leaf than usual, or stop after one or two small pours. Count what you drink across the whole session, even when each cup is small. A quick rinse or a later steep can change how much caffeine is in the next pour, but neither guarantees a caffeine-free cup. The amount extracted across steeps depends on brewing conditions.
2. Move your tea session earlier
If you enjoy ripe pu-erh after dinner but find yourself lying awake later, try having the same tea with lunch. Keeping the tea and serving similar makes it easier to notice whether the timing makes a difference. Research links caffeine to taking longer to fall asleep and getting less sleep overall. How much it affects you depends in part on the dose and your own sensitivity. There’s no universal 3 p.m. cutoff.
3. If you want to avoid caffeine, switch drinks
When you want a warm evening drink without caffeine, choose a caffeine-free infusion. Check the ingredients if it’s a blend. Tea age and the colour of a third pour don’t tell you whether it’s caffeine-free. Even drinks labelled decaf can contain some caffeine.
