It works for all strengths and for all types of tea. You can even check out the formulas to see how I’ve calculated the brewing times for each consecutive brew.
Sometimes, the later brews have no times by them. At this point, leave the tea in the pot to steep indefinitely while you finish drinking.
To improve this calculator, I need feedback! Plug in the values of how you brew your tea and let me know whether the brewing times are correct. Tweak the constants if necessary. What values of β and c work best for your favourite brew?
