This gets a bit technical, so I'll try to make it short.

There are three varieties of common caffinated teas; green, oolong, and black teas, which all come from the leaves of the Camellia sinensis plant. What sets green tea apart is...

Does decaf black tea still have caffeine in it?

I heard that decaf black and green tea still have large amounts of caffeine in it. I also heard that formaldehyde is used to decaffeinate teas. Is this stuff true?


Decaf tea has a lot less caffeine -- enough so that it doesn't bother most (not all) people. Information on the amount of caffeine can be found here: http://www.stashtea.com/caffeine.htm

Why does green tea have less caffeine than black tea?

is there a difference in the caffeine that we find in black tea and the one in coffee?

What percentage of caffeine does black tea usually have?

I just got one that says "98% caffeine free" and I'm wondering if that's lower than average?

yeah if the cup was a teacup size, 250mls, like 8 fl. oz....


1 cup has around 50 milligrams of caffeine depending on cup size and brewing strength. Less than average cup of coffee.

    Here’s a cool mind hack for you

    Caffeine and napping seems like a counter intuitive concept.  Isn’t caffeine supposed to keep you awake?  True, but read on to find out why scientists recommend this mind hack.

    The idea of the “caffeine power nap” is to have a coffee, or similarly caffeinated beverage, before your nap.  By the time the caffeine has kicked in, you will either be fast asleep or just waking up.

    Before I get into the details as to how this works, lets take a look at power naps.   How much sleep did you miss last night?  If your a monophasic sleeper (which means you get your sleep all in one block), did you get 7-8 hours?  If you got less than this, you probably have a sleep debt and need to make it up somehow.
