This is the kind of tea set that is used in Taiwan for tea judging competitions. Official competitions will use 3 grams of tea and brew it for 5 minutes. This is a way of brewing everything out of the tea so that every little component of the tea is apparent. When you brew with these sets, pay attention to the color of the liquid. The tea will almost certainly be bitter, but how quickly does that bitterness turn into sweetness, if at all? This is a great way to experience a new side of any of your teas!
