I sometimes wonder how much caffeine I actually drink everyday. I normally only drink one sitting of tea a day, using a smallish (100ml or less) pot, and filling it anywhere between 1/4 to 1/2 full. I will drink it until it tastes like nothing other than sweet water, and that could be anywhere from 10-30 infusions.
The normal amount of caffeine in a cup of tea varies wildly, since how you brew and what you brew makes a huge difference in the amount of caffeine you get. So they say the average is 50mg of caffeine in a cup of 5oz tea…. which doesn’t really mean anything to me, since I have no idea how they actually arrive at such numbers, and how that compares with how I brew mine. I drink far more than 5oz of tea, obviously, but it seems to me that unless you’re comparing weight of the leaves used per ounce of fluid, the comparison is almost meaningless.
Is there a way to test for caffeine? This is, of course, purely out of curiosity, but it’s nevertheless something that I am interested in knowing, if nothing else, because other people ask me all the time…. “which tea has less caffeine?”
