The coffee vs. tea debate is a dangerous thing to talk about because both sides aren’t willing to take it easy. Both the beverages have their devotees, and you need to be prepared for a heated argument when you broach this subject. Why is the debate such a big thing you ask? Well, because both the beverages are excellent sources of caffeine, and are a part of the lives of people around the world. Still, we’re settling the score once and for all. Here are all the differences between tea and coffee.

Coffee vs. Tea

The Plants

Coffee comes from the Coffea plant, which is a small tree, or evergreen bush that is grown between the tropics of Cancer and Capricorn. These trees grow up to 10 meters tall, though most are trimmed to about 5m to keep them more manageable. The genus of the tree is Coffea, which belongs to the family Rubiaceae. These plants are native to Africa and Asia, however, they have since been planted in regions all over the world. The source plants are the biggest difference in coffee vs. tea.

Tea on the other hand comes from the Camellia Sinensis plant. These trees or shrubs belong to the Theaceae family, which is a family of flowering plants. There are two major varieties of tea plants. These are the C. Sinensis var. Sinensis and C. s. var. assamica. The multiple types of teas are all obtained from these two types, through various levels of maturation, oxidation, and roasting.

The Source

Coffee is made from coffee beans, which are essentially seeds of the coffee plant. After the coffee plant matures, it produces coffee cherries, which are allowed to ripen. These cherries are all then picked by hand. When these berries are opened, the seed inside is extracted. This is what we call the coffee bean, and this is cleaned, and then sold in the market either roasted or unroasted.


Tea is made from the leaves and buds of the tea plant. These leaves and buds are dried and allowed to oxidize and are finally sold in the market in the dried stage. The different types of tea are picked at separate intervals and are allowed to oxidize to give different flavors. The part of the respective plants that are used to make the coffee is a significant one from all the coffee and tea differences.

Caffeine Content

Coffee is a very popular source of caffeine throughout the world. The caffeine content can be slightly altered because of the brewing method, however, hot coffee should have an estimated 40 mg of caffeine per 100g of coffee. A healthy adult can consume about 400 mg of caffeine in a day according to the Food and Drug Association, FDA. So the caffeine in coffee is perfectly safe to consume.


Tea, on the other hand, sees a decrease in caffeine content by more than 50%. 100g of tea contains about 11 mg of caffeine only. So if you’re someone that needs more caffeine, coffee is the drink you should choose.

The Brewing Temperature

Coffee can be either hot-brewed, or cold brewed. Hot brewed coffee is made between 195 degrees Fahrenheit and 205 degrees Fahrenheit. Cold-brewed coffee is made at around 68 degrees Fahrenheit.

Tea is brewed at a lower temperature which is why the caffeine isn’t completely extracted from the leaves, and tea has less caffeine. This temperature is between 140 degrees Fahrenheit to 200 Fahrenheit for special green teas.

The Taste

Coffee is bitterer and more acidic than caffeine. This is because the hot water strips the acidic elements and caffeine into the brew. These acidic elements are then turned bitter by the whole water. This is why cold coffee is less acidic and less bitter than hot coffee. However, even cold coffee is more acidic than tea is. The taste of coffee is also the same no matter how it is brewed, and you have to choose additives to make it vary.


Tea, in contrast, comes in a wide variety of natural flavors. Although all the tea comes from the two varieties of the camellia Sinensis plant, the differences in oxidation make for a wide range of flavors. Different types of tea can have flavors ranging from earthy tones, to even citrusy tastes. Herbal teas have an entirely different palate, however, they cannot be considered real tea. This is because these do not come from the camellia Sinensis plant.

The Health Benefits

Contains Helpful Antioxidants and Anti-inflammatory

Antioxidants in coffee help clean up free radicals from the body. These free radicals can cause cell damage, and in worse cases, cancer. Not just antioxidants, but coffee has a lot of anti-inflammatories too. These prevent a plethora of diseases.

Reduces Chances of Type II Diabetes

According to, coffee can help reduce the risk of diabetes by about 6%. This is said to be because caffeine preserves the activity of beta cells in the pancreas. These cells are what produce the hormone insulin in the body, which is important for removing excess sugar from the blood, by signaling the liver to start storing it. Without insulin, the body is unable to remove the excess sugar from the blood, and this condition is called Type II diabetes. Coffee also reduces insulin resistance in the body and thus makes it more effective. Not just this, but the plethora of antioxidants and anti-inflammatories in coffee also help prevent the development of diabetes.

Increases Attention and Work Capability

This is because of the high amounts of caffeine in coffee. Coffee inhibits the working of the hormone adenosine, which accumulates in the brain to make you sleepy. Not just this, but coffee also makes the body produce adrenaline, which makes you more energetic, and alert.  Tea does this too, though the effect isn’t as strong, since tea has less caffeine.

The Coffee vs. tea debate may be extensive, but we’ve done our best to sum it all up for you. Both brews have their advantages and disadvantages, as well as very complex histories, and we believe only the consumers can be the judges. After all, what the choice ultimately comes down to is your taste. Whether you like coffee or tea, depends on whether you like your drink acidic and bitter, or milder. It also depends on how much caffeine you want to consume, and what flavors you prefer. Whichever brew you like, we recommend you take it in moderation. Excessive consumption is never a good thing.
