Re-steeping tea is a great way to get more from every tea leaf. In fact, one of the many benefits of drinking loose leaf tea is that it can be re-steeped several times, depending on the type of tea and your taste.
The general rule is that oolong, green, white and black teas can all be re-steeped. Most herbal teas, due to the delicate nature of the ingredients, should not be re-steeped as they don’t hold up very well the second time around.
To re-steep your tea, simply save your tea in the tea basket and place it in an empty cup or saucer; when you’re ready to re-steep, place the basket back in your tea pot or cup and re-brew. Note that the steep time and temperature will not vary between the first brew and subsequent brews.
If you do not reuse your tea after six hours or so, it’s best to throw out the steeped tea and start fresh. Many tea drinkers like to keep a pot with them all day long, so it’s not uncommon to get three steeps out of the same basket of tea.
Because there are no hard and fast rules about re-steeping, you should play around with it until you find a steeping/re-steeping combination that suits your taste.
