How much caffeine is in Earl Green Tea?

Earl Grey tea is a popular flavored tea that is typically made from black tea leaves flavored with bergamot oil. The caffeine content of Earl Grey tea depends on the type and amount of black tea used in the blend. On average, an 8 ounce (250 ml) cup of Earl Grey tea contains about 40-60 mg of caffeine, which is slightly less than a regular cup of black tea.

What is Earl Grey Tea?

Earl Grey tea refers to a flavored tea blend made by infusing black tea leaves with bergamot oil. Bergamot is a citrus fruit that gives Earl Grey its distinctive aroma and flavor. The tea is named after Charles Grey, the 2nd Earl Grey, who was said to have been gifted a tea flavored with bergamot oil in the 1830s. Earl Grey tea was popularized in England but is now enjoyed around the world as a flavored alternative to regular black tea.

There are a few different varieties and blends of Earl Grey tea available today. The main types include:

  • Classic Earl Grey – Made with black tea and bergamot oil. This is the traditional Earl Grey blend.
  • Lady Grey – Earl Grey tea with added lemon and orange peel.
  • Russian Earl Grey – Contains Earl Grey tea blended with citrus fruits and Russian caravan tea.
  • French Earl Grey – Black tea with bergamot and French blue cornflower petals.

The base black tea used can also affect the caffeine content. Many commercial Earl Grey teas use lower caffeine Assam black tea as the base. But others use Ceylon black tea or even higher caffeine Chinese black teas.

How Much Caffeine is in Earl Grey Tea?

The caffeine content of Earl Grey tea depends primarily on two factors:

  1. Type of black tea used as the base
  2. The proportion of black tea to flavored tea

On average, Earl Grey made from pure black tea contains around 55 milligrams of caffeine per 8 ounce cup. This is considered moderate caffeine, slightly less than a typical cup of coffee.

However, many commercial Earl Grey blends use a smaller proportion of black tea diluted with flavored tea leaves or oils. The more the black tea is diluted, the lower the caffeine content. Here is the caffeine range found in different types of Earl Grey tea blends:

Type of Earl Grey Caffeine (per 8oz cup)
Classic Earl Grey (100% black tea) 55 mg
Premium Earl Grey (80% black tea) 45 mg
Commercial Earl Grey (60% black tea) 35 mg
Flavored Earl Grey (40% black tea) 25 mg
Decaffeinated Earl Grey 2-5 mg

As you can see, a strong Earl Grey made with 100% black tea contains about 55 mg of caffeine per 8 ounce serving. But lighter commercial blends can have as little as 25 mg. And decaf Earl Grey still contains trace amounts of caffeine.

Earl Grey Caffeine vs Coffee

Compared to other popular caffeinated beverages, Earl Grey tea has far less caffeine than coffee but slightly more than green or white tea. Here is how an 8oz serving of Earl Grey compares:

  • Earl Grey tea (40-60mg)
  • Green tea (25-40mg)
  • Black coffee (95-165mg)
  • Espresso (60-100mg)

As you can see, a cup of Earl Grey made with pure black tea contains about half the caffeine of a regular coffee. However lighter Earl Grey blends fall between green tea and coffee in caffeine content.

Factors that Affect Caffeine Levels

There are a several factors that can affect the caffeine content in a cup of Earl Grey tea:

Type of tea used

The base black tea determines the starting caffeine level. Teas like Assam and Ceylon contain slightly more caffeine than others. Chinese black teas tend to be highest.

Blend ratio

The proportion of black tea to flavored tea or oils can significantly alter the caffeine content. Lighter blends have less caffeine.

Brewing time

The longer Earl Grey tea is brewed, the more caffeine will be extracted into the water.

Water temperature

Hotter water temperatures allow more caffeine to be extracted during brewing.

Tea leaf grade

Finer broken grades of black tea leaves release caffeine faster than larger leaf grades.

Multiple steeps

The caffeine level declines with each subsequent steeping of the same tea leaves.
