Caffeine in tea

I haven’t been able to find it on here or online. Generally how much caffeine is in black tea?
My step father recently had to cut out caffeine (from coffee) in his diet due to high blood pressure. With my weight it’s something I worry about.

So what is the difference between coffee & tea?

Short answer: tea tends to have less than coffee, but the exact amount is highly variable. I’ve seen estimates from 14mg to 85mg per 8oz serving. Using more leaf, hotter water, and steeping longer will all increase the amount of caffeine in your drink.

The best sources I’ve found for how much caffeine is in tea are here:

Though if anyone has anything more recent or detailed I’d love to see it.

I know matcha has about 30-40mg of caffeine per serving. A strong cup of coffee can have up to 200mg of caffeine, which is quite strong, and can be unsettling for some people.

I think you can get decaffeinated black tea? Here is something I just found by doing a quick google search:

I grew up drinking Orange Pekoe tea, it is really soothing, tastes great, and has very little caffeine.
