Flavored teas are made by adding flavoring agents to tea leaves.
The flavoring agents can be natural or nature-identical.
They are thicker than water but thinner than olive oil. The amount of flavoring agent used depends on the desired flavor and strength, but is usually between 0.5% and 5% of the weight of the tea.
Flavored teas can be made with:
Plant extracts
Flowers, herbs, spices, or smoke
Flavorings or perfumes
