The reasons why honey grapefruit tea is bitter may be as follows:

1. The inner skin, pedicle and core of grapefruit contain bitter substances. If they are not completely removed or cooked, It will affect the taste of tea.

2. Too much sugar will mask the taste other than sugar. If too much honey is used, the taste will be sweet and the fragrance of grapefruit will be lost.

3. The wrong cooking method, such as the water temperature is too high and the time is too long, will also increase the bitter taste of grapefruit tea.

In order to make honey grapefruit tea taste better, it is recommended to use mature grapefruit, remove the inner skin, pedicle and core part, cut the grapefruit flesh into small pieces or shreds, and then boil it in boiling water for 10- 15 minutes, then add appropriate amount of honey to taste.
