There are many variations of Earl Grey tea, including loose-leaf tea, tea bags, and flavored blends.

Caffeine – What is it?
Caffeine is a naturally occurring stimulant that is found in many drinks, including tea, coffee, and energy drinks. It works by stimulating the central nervous system, increasing alertness and reducing fatigue. Caffeine is also known to improve cognitive function, enhance mood, and boost metabolism.
However, excessive caffeine intake can have negative effects on the body, such as jitteriness, insomnia, and increased heart rate. The recommended daily caffeine intake for adults is 400 milligrams, which is equivalent to about 4 cups of coffee or 10 cups of black tea.

On average, a cup of Earl Grey tea contains between 30 to 60 milligrams of caffeine. This is lower than the caffeine content in coffee, which can range from 95 to 200 milligrams per cup.
Several factors can affect the caffeine content in Earl Grey tea, such as the type of tea leaves, the water temperature, and the brewing time. Loose-leaf Earl Grey tea tends to have a higher caffeine content than tea bags. Steeping the tea for a longer period can also increase the caffeine content.
