- Does the tea become aged-tea after being roasted?
Only those which have been stored for a long period of time would be called aged-tea. During the period of storage, the taste of tea could be changed by the moisture level in the environment. So we need to apply sufficient roasting level to lower the moisture content.
If the tea is given heavy roasted without being stored, it is not aged-tea.
If the tea has been roasted too much, it would not only burn the tea leaves and destroy its quality, but also making it difficult to open up when brewing.
- The Science behind Roasting.
1. Maillard reaction: the amino acid and carbohydrate in the tea leaves would release rich aroma when being heated under the temperature of 118℃ (244℉). This can often be seen in food processing, such as meat pan-frying.
2. Evaporation of Caffeine: applying a longer time on heating will make the caffeine within the tea leaves evaporated, leading to lowering the astringent feeling in the tea.
- Is charcoal-roasting better?

The casus of abdominal pain may include tea polyphenols and caffeine. During the roasting process, the caffeine level will be lowered while the tea polyphenols almost remains the same.
