Anyone know how much caffeine green tea has compared to black tea?
Pound for pound Leaf for leaf, green tea will have more caffeine than black because it's less processed. Cup for cup is fuzzier because of different brewing methods, but Google might have some guidelines.
According to this page: [link]
An average cup of green tea contains approximately 30 mg of caffeine. This compares to a cup of black tea, which has about 40 mg, and a cup of brewed coffee, which has 120 mg of caffeine.
But you know if all depend on how long something is steeped and the tea and the glayvin.
According to this page: [link]
Huh - just found that exact same link.
Oh, and I just noticed that my Bigelow green tea says to steep one to two minutes. I've been steeping it for about five. But OTOH I'm not using boiling water, just hot water out of a water cooler thingie.
Republic of Tea has a table.
Except that this:
The longer the tea leaves have fermented during manufacture, the greater their caffeine content.
Is really poorly worded. You can't increase a tea leaf's caffeine content by fermenting it, you can only concentrate it. Since fermenting dries out the leaves, a higher percentage of what's left is caffeine than before. But there isn't more caffeine in a fermented tea leaf than there is in an unprocessed one.
That page needs to be updated to take into account the influx of energy drinks. The market's mad right now.
They should come out with a drink that has even more caffeine and call it "Crank" or somesuch.
Which reminds me - I just cracked the hell up during that Simpsons episode where Homer becomes a truck driver and takes some "stay-awake" pills called "Stimucrank."
Wikipedia has an incomplete but more current list. Cocaine's fucked up, man. Easily 3x the caffiene of most of the drinks out there.
tommy, there's a Crunk!!! that's pretty caffeinated...
