Bok's comments returns us to what an individual experiences versus what one reads science shows. The best example of this for me is that researchers never said that there was proof that chocolate causes acne or worsens acne. In lab tests there was no chemical proof. Yet, I know from teenage years to my senior years that eating chocolate one day will produce pimples the next day (and when I was young, a real mess). A billion other people (probably) know the same thing.Bok wrote: ↑Tue Nov 13, 2018 5:04 amBut then what about the effect on sleep? You can drink aged tea all night without having trouble to sleep, which can not be said about younger teas. I thought that was correlated to the caffeine? Or does the nature of it change? Not firm on the chemistry at work...
Back to tea, the why's of effects are for speculation (mostly for fun) but the reporting of effects is useful. I recently got 20 grams of ten-year old roasted oolong. I have drunk a lot of cups of it at night a few times without it stopping me from sleeping regularly. Perhaps that tea does not hurt sleep because it has less caffeine; perhaps because it is smoother on the tummy. Whatever the reason, the aged tea is good for late night drinking.
