Caffeine – What Is It, and How Does It Work?
Before we answer the question, “what has more caffeine, coffee or tea?”, let us first look at this stimulant. Caffeine is a bitter, white crystalline xanthine alkaloid that acts as a psychoactive stimulant drug. It is found in the seeds, leaves, and fruits of over 60 plants including coffee beans, tea leaves, kola nuts, and cacao pods. It can also be produced synthetically.
In humans, caffeine acts as a central nervous system (CNS) stimulant, temporarily warding off drowsiness and restoring alertness. It is the world’s most widely consumed stimulant. The effect of coffee and tea on sleep is controversial. Some studies suggest that it does not disrupt sleep, while others indicate that it may reduce the time spent in deep sleep. Other effects include increased heart rate, increased respiration, and blood pressure. Some people should avoid caffeine, such as those with anxiety disorders or high blood pressure. So, what has more caffeine, coffee or tea?
How Much Caffeine Is in Coffee and Tea?
Now that we know what caffeine is and what it does, let’s look at the levels of this stimulant in coffee and tea. In order to determine what has more caffeine, coffee or tea, it must be noted that not all types of coffee and tea have the same amount of caffeine. The levels also depend on how the beverage is prepared.
Caffeine levels also vary depending on what kind of tea leaves are used. Black tea generally has more caffeine than green tea because it is allowed to oxidize for a longer time. This oxidation process causes the caffeine to be more soluble, making it easier to extract when brewing the tea. The longer the leaves are oxidized, the higher the caffeine content. So, which has more caffeine, coffee, or tea?
Which Has More Caffeine, Coffee or Tea? Caffeine in Coffee
So, what has more caffeine, coffee, or tea? The answer is that it depends on the type of coffee or tea and how it is prepared. In general, coffee has more caffeine than tea, but there are exceptions. For example, matcha green tea powder mostly has more caffeine than coffee because it is a concentrated form of green tea.
Matcha green tea powder contains about 20 to 40 grams of caffeine per gram (about 40-170 mg per cup). By contrast, an 8-ounce (237 ml) cup of coffee made with brewed ground beans contains 95 milligrams of caffeine. So, which has more caffeine, coffee or tea? The answer depends on the type of coffee and tea.
Caffeine Content in Tea and Coffee – Black Tea and Green Tea
Caffeine levels can vary – both in coffee or tea. However, generally speaking, coffee has more caffeine than tea. In order to compare these two beverages, let us look at the average levels of caffeine in both.
The average level of caffeine in black tea is about 50 mg per average cup (237 ml). The average level of caffeine in coffee is 95 mg per cup. So, what has more caffeine, coffee or tea? Coffee typically has two times more caffeine than tea.
It should be noted that there are exceptions. Black tea is the strongest when it comes to caffeine levels. Green tea, on the other hand, is lower in caffeine. The amount of caffeine in green tea can vary depending on the variety, but it usually has 28 mg per cup.
A Cup of Tea vs a Cup of Espresso
Now that we know the average levels of caffeine in both coffee and tea, what about specific types of these beverages? For example, what has more caffeine – a cup of tea or a cup of espresso?
A regular cup of tea usually has 50 mg of caffeine. A cup of espresso, on the other hand, has about 64 mg of caffeine. So, what has more caffeine – coffee or tea? If we look not at the portion sizes, but at the caffeine levels, espresso has more caffeine.
However, it is important to note that the portion size of espresso is much smaller than that of a regular cup of tea. In general, 100g of espresso has about 212 mg of caffeine. Tea has only 11 mg of caffeine per 100g.
Therefore, when it comes to what has more caffeine – coffee or tea – it also depends on the portion size. If we compare equal amounts of each beverage, espresso has more caffeine. But if we compare two cups of tea to just one espresso, it may not be as clear what has more caffeine.
It all comes down to how the coffee or tea is prepared, what kind of beans or leaves are used, and how much of the beverage you’re consuming. So, what has more caffeine – coffee or tea? It depends on a variety of factors!
