Final Thought
English breakfast tea is a morning favorite enjoyed by millions around the world. Known for its strong flavor and classic taste, it’s a staple in many people’s morning routine.
In this article we will look at the caffeine content of the tea, a popular black tea blend that’s part of the black tea family which is diverse and has many regional origins.
We will compare it with green tea, herbal tea and white tea, look at the factors that affect its caffeine level and its health benefits.
What is English Breakfast Tea?
English breakfast tea is a traditional blend of black teas, usually a combination of Assam, Ceylon and Kenyan black tea leaves to make a malty tasting tea with full body. This blend of black teas gives a strong, rich flavor that pairs well with milk and sugar, making it a classic breakfast tea.
The tea is made from the leaves of the Camellia sinensis plant, the same plant that produces green and Earl Grey tea. Compared to other black teas, English breakfast tea has similar caffeine content and robust character but its specific blend gives it a malty flavor and depth.
This tea is brewed by steeping loose leaves or tea bags in hot water for about 3 minutes to make a delicious, calorie free drink that gives a morning boost.
Does English Breakfast Tea Have Caffeine?
When it comes to caffeine content, English breakfast tea does contain caffeine, but the amount varies. Typically, a cup of English breakfast tea contains about 40 to 70 mg of caffeine per cup. That’s a moderate amount of caffeine compared to other drinks.
For those wondering how much caffeine is in their morning cup, it’s worth noting that the caffeine content is enough to give an energy boost and help you feel alert without the jitters that come with higher caffeine drinks like coffee.
Factors That Affect Caffeine Level
Tea Format

Caffeine level of this tea can vary depending on whether you use loose leaf or tea bags. Consider the following:
-
Loose leaves have whole or larger pieces of tea leaves which release caffeine more gradually.
-
Tea bags have smaller broken leaves or fannings which brew faster and sometimes result in a slightly higher caffeine extraction.
Both come from the same black tea blend but brewing method and leaf size can affect the caffeine in your cup.
Steeping Times

How long you steep your tea also affects the caffeine level. Brewing the black tea for three minutes is typical and provides a balanced flavor and caffeine level.
But if you steep longer, more caffeine is extracted from the tea leaves and more caffeine in your cup. Steeping shorter results in less caffeine and lighter flavor. So steeping time is a key factor in how much caffeine you consume.
Serving Size

Size of your serving also matters. A larger cup will have more caffeine simply because there is more liquid infused with caffeine compounds from the tea leaves. Whether you drink an 8oz cup or a larger mug, the caffeine intake will vary.
For example a cup of English breakfast tea in a larger mug will have more caffeine than a smaller cup, so portion size is important in your overall caffeine intake.
English Breakfast Tea vs Other Teas
Tea lovers have many options when it comes to choosing their perfect cup, each with different caffeine levels and flavor profiles. Knowing this helps tea drinkers choose the right tea to fit their caffeine needs and flavor preferences, whether they want a stronger morning boost or a gentler, more relaxing experience.

English Breakfast Teas vs Coffee

When comparing English breakfast tea with brewed coffee, the caffeine difference is big. A standard cup of coffee has about 95mg of caffeine or more, that’s roughly twice the amount of caffeine in a cup of English breakfast tea.
So the tea is a great option for those who want a drink with less caffeine than coffee but still want a traditional morning drink. Plus the tea’s malty taste and classic flavor is a different sensory experience to the bold sometimes bitter taste of coffee.
Health Benefits of English Breakfast Tea
Beyond its caffeine content, this tea is a calorie-free beverage that contains natural plant compounds such as polyphenols, which are being studied for their potential role in general wellness. Black tea contains natural plant compounds including polyphenols that are the subject of ongoing research into their connection to general wellness.
Some studies have explored a potential link between black tea consumption and markers related to blood pressure. While this research is ongoing and findings are not conclusive, it suggests that tea may play a role in supporting general wellness when enjoyed as part of a healthy lifestyle.
Some studies have also looked into possible links between tea consumption and focus and alertness, which may be related to its caffeine content. Research is ongoing, and individual results may vary. Tea is best enjoyed as part of a balanced lifestyle.
