Chinese tea travel cup
Because the tea leaves inside are continuously steeping (and thus continuously getting stronger) you will need to do some combination of the following:
A. Use less dry leaf.
B. Use cooler water.
C. Drink the tea faster.
D. Drink bitter tea.
B. Use cooler water.
C. Drink the tea faster.
D. Drink bitter tea.
I'll usually do some combination of A, B and unfortunately D. Also, it is worth noting that some teas do much better in these cups than others. You are free to make up your own mind about that, but I generally recommend oolongs or puer teas because they have larger leaves. Big leaves release their flavor slower than small ones because they have less surface area in contact with the hot water.
Sipping oolong on the deck
Of course, you don't have to drink directly out of it. More often than not I find myself decanting the liquor into another cup or mug.

These cups are great for travel. You don't have to worry about them breaking and you can even stuff some small tins and baggies of loose tea inside them to save room in your pack.
