Tea can be a little confusing when it comes to the kinds and caffeine amount. So to put an end to all the questions and wondering, we have compiled a guide on the types of tea and caffeine. Check it out.
Tea can generally be divided into these categories: black, dark (or pu-erh), oolong, yellow, green, herbal, white, fruit, honeybush, decaf black, and rooibos.
Types of Black Tea and Caffeine
Black tea is one of the most popular types of tea in the west due to its strong flavor and long shelf life. Before it becomes the black tea that we all know and love, it goes through a process called oxidation where water evaporates out of the leaf and the leaf absorbs more oxygen from the air. Black tea specifically goes through the full oxidation process, resulting in dark brown and black leaves.
Black tea has a stronger caffeine content compared to other teas. It contains around 60 to 90 mg of caffeine per 8 ounce cup.
Types of Dark Tea and Caffeine
Dark tea, or pu-erh, is an aged tea from China that is post-fermented. It has gone through microbial fermentation from several months to years. Exposing the leaves to humidity and oxygen during the process causes endo-oxidation and exo-oxidation. It tends to smell slightly earthy but doesn’t carry over into the flavor. It can taste light to heavy, smooth, and with a sweet floral flavor.
To make dark tea, it is recommended that one use a little more per cup than other teas. It can also be re-steeped for multiple cups of tea. Our Vanilla Rose Dark Tea Hearts are a perfect example of a dark tea that can be steeped again and again.
Dark tea contains about the same caffeine content as black tea, 60 to 90 mg of caffeine per 8 ounce cup.
Types of Oolong Tea and Caffeine
Oolong tea goes under partial oxidation. The flavor isn’t usually as strong as a black tea and has many fragrant and intriguing tones. Many people compare the flavor of oolongs to flowers or fruit.
Oolong tea normally contains about 50 to 75 mg of caffeine per 8 ounce cup.
Types of Green Tea and Caffeine
After being picked, green tea is allowed to wither a bit and then the oxidation process is stopped by heating the leaves. That is why it is brewed at lower temperatures and has less caffeine. It also contains a subtler flavor compared to other teas.
Green tea contains about 30 to 50 mg of caffeine per 8 ounce cup.
Types of Yellow Tea and Caffeine
Yellow tea goes through a longer oxidation process than green teas and a slower drying period. It is on the rare side and similar to green tea in appearance and flavor.
Yellow tea has a caffeine content of about 32 mg per 8 ounce cup.
Types of White Tea and Caffeine
White tea is not oxidized, just like green tea. It has a lighter flavor than black tea and normally has a yellowish color. It is known for its floral and fruity aromas.
The amount of caffeine in white tea can vary from about 15 to 20 mg of caffeine per 8 ounce cup.
Types of Decaffeinated Black Tea and Caffeine
Decaf tea is made after picking while the leaves are still green. There are several methods of caffeine removal, including the solvent methylene chloride, ethyl acetate, and carbon dioxide. All of Plum Deluxe’s decaf teas are decaffeinated using the carbon dioxide method.
Decaf tea has almost no caffeine, with at most 3 mg per 8 ounce cup.
Types of Herbal Tea and Caffeine
Herbal teas do not come from the camellia sinensis plant, unlike the other teas. They are made from steeping or boiling herbs. Herbal tea doesn’t contain any caffeine and makes for a great drink when you want to relax and unwind.
Types of Fruit Tea and Caffeine
Fruit tea is, as the name suggests, an infusion of fruit flavors that are enjoyed hot and cold. It is essentially a mixed blend of dried fruit, herbs, leaves, blossoms, petals, and other ingredients. When mixed with hot water, it extracts flavor from the ingredients, which creates great blends such as Pineapple Pop kona pop, Peach Bellini peach apricot tea, and Self Care Blend apricot tea.
Fruit tea normally does not contain any caffeine.
Types of Honeybush Tea and Caffeine
Honeybush tea is a South African herbal tea made from the leaves of the honeybush plant. The shrub has a honey-like smell which is where the name comes from. To make the tea it undergoes full oxidization, which gives the leaves a red color.
Honeybush doesn’t have any caffeine.
Types of Rooibos Tea and Caffeine
Rooibos tea is an herb native to South Africa. It is technically a plant that, when harvested and dried, can be brewed into a reddish-brown herbal infusion. Two fantastic rooibos-based blends are White Chocolate Peppermint delicious white chocolate peppermint tea and Pears and Cinnamon herbal tea.
Rooibos tea has no caffeine.
