I drink a variety of tea as I like to try all kinds of taste. However I don't drink everyday. The most commonly one that I drink is green tea and I brew myself instead of those in sachet form. I particularly like those from China and Japan but these imports cost more. There are also some instant ones in a bottle or can which has very high content of sugar which I highly discouraged. Adding jasmine in the tea will give you the fragrance smell. If natural honey is added, it gives the sweetness and honey can be used in most tea. It is definitely better than sugar as honey is also consumable for people who have diabetes.
As for milk, I don't add it in the tea as I prefer the natural taste and fragrance. If milk is needed, try to add a very small amount so as to preserve the taste or else it will be so milky as if you are drinking milk instead of tea.
