Which Has More Caffeine: Coffee or Tea?

Coffee and tea are two of the most popular drinks on the planet. One, or both, of these drinks is a part of the daily routine of billions of different people around the globe.

One of the main reasons that people find so much value in both coffee and tea is their caffeine content. Both of these drinks provide a boost of caffeine, a mild nervous system stimulant that is lauded for its role in helping humans maintain attention and staying awake.

So, if you are looking for a caffeine boost, which of these two drinks should you choose? Let’s explore further.


Tea is a drink that is made by pouring hot water over dried leaves that are taken from a plant that is cultivated in mild, wet places. 

While green tea and black tea have significant production and flavor differences, both contain about the same amount of caffeine per 8 ounce cup. You will typically find between 25 and 35 milligrams of caffeine in an average cup of tea, which is considered to be a mild dose.


Coffee is a drink that is made by adding hot water to the ground form of beans obtained from a genus of flowering plants that are native to Africa and Asia and cultivated in warm tropical environments.

Coffee is commonly drunk either in an espresso-based or a drip brew-based format. One shot of espresso, which measures about an ounce, contains about 50 to 60 milligrams of caffeine.

Meanwhile, a larger, eight-ounce cup of brewed coffee typically contains anywhere between 100 and 160 milligrams of caffeine, depending on the strength of the brew. Coffee is definitely your best choice for a big caffeine boost!
