Types of Tea: Complete Guide to Black, Green, Oolong, White & More
Types of Tea: Complete Guide to Black, Green, Oolong, White & More
There are many types of tea, from bold black tea and fresh green tea to fragrant oolong and delicate white tea. The differences come mainly from the tea plant, the leaves used, and how the leaves are processed.
Most traditional teas come from the same plant, Camellia sinensis. Black, green, white, and oolong teas are different because producers process the leaves in different ways. Herbal teas are different because they are made from other plants, flowers, spices, or herbs rather than Camellia sinensis.
For cafés, restaurants, tea shops, and bubble tea businesses, understanding these differences makes it easier to choose the right tea base for different drinks.
What Are the Main Types of Tea?
The main types of true tea are:
Black tea
Green tea
Oolong tea
White tea
Dark tea, including pu-erh
Yellow tea
Herbal teas are also widely called tea, but they are technically herbal infusions rather than true teas because they do not come from Camellia sinensis.
The Tea Association of the USA identifies black, green, oolong, dark, and white tea as varieties that come from the tea plant. Their differences are mainly related to processing and oxidation.
1. Black Tea
Black tea is one of the most widely consumed types of tea. Its leaves undergo substantial oxidation during production, which gives the finished tea a darker color and stronger flavor.
Black teas can range from smooth and balanced to bold and malty.
Common black tea styles include:
Assam
Ceylon
Taiwanese black tea
Sun Moon Lake black tea
English Breakfast
Earl Grey
Darjeeling
Black tea also works well in milk tea because its stronger flavor can stand up to milk, sugar, and other ingredients.
For bubble tea businesses, YIOUYI offers several black tea options, including Sun Moon Lake Black Tea, Taiwanese Black Tea, Ceylon Black Tea, Assam Black Tea, and Traditional Flavor Black Tea.
2. Green Tea
Green tea is made from Camellia sinensis leaves that are processed to limit oxidation.
Compared with many black teas, green tea often has a lighter color and a fresher flavor. Depending on the variety and processing method, it can taste grassy, vegetal, nutty, floral, or slightly sweet.
Popular green tea styles include:
Japanese green tea
Chinese green tea
Jasmine green tea
Matcha
Sencha
Dragon Well
Green tea can be served hot or cold and is also commonly used as a base for fruit tea.
YIOUYI's green tea range includes Finest Camellia Green Tea, Yiouyi Green Tea, Yiouyi Jasmine Green Tea, Jade Green Tea, and Finest Green Tea.
3. Oolong Tea
Oolong tea sits between green tea and black tea in terms of processing. It is partially oxidized, and producers can create many different flavor profiles by controlling the processing.
Some oolong teas have floral and fruity notes, while darker roasted oolongs can have deeper roasted flavors.
This wide range makes oolong useful for both traditional tea and modern beverage menus.
Common oolong styles include:
Taiwanese oolong
Tieguanyin
Dark roasted oolong
Charcoal-roasted oolong
Milk oolong
YIOUYI offers Classic Oolong Tea, Yiouyi Oolong Tea, and Charcoal Roasted Oolong Tea for beverage applications.
4. White Tea
White tea is generally made with young tea buds and leaves and undergoes relatively limited processing.
It usually produces a lighter-colored infusion with a delicate flavor.
White tea can have subtle floral, sweet, fruity, or fresh notes, depending on the variety and production method.
Because its flavor can be delicate, preparation matters. Very strong flavors or excessive sweeteners can cover its natural character.
5. Dark Tea and Pu-erh
Dark tea is another major tea category. Pu-erh is one of the best-known examples.
Unlike green tea, black tea, and oolong tea, some dark teas undergo microbial fermentation or post-fermentation as part of their production.
Pu-erh can be sold as loose tea or compressed into cakes and other forms.
Its flavor can range from earthy and woody to smooth and mellow, depending on the tea and its processing and storage history.
6. Yellow Tea
Yellow tea is a less common category than black or green tea.
It is produced using processing steps that are related to green tea but include an additional yellowing stage.
Yellow tea can have a gentle flavor that falls between some green and white tea styles.
Because it is less common in many markets, availability can be more limited.
7. Herbal Tea
Herbal tea is not technically true tea.
Instead, herbal infusions can be made from flowers, leaves, roots, fruits, spices, and other plant materials.
Common examples include:
Chamomile
Peppermint
Hibiscus
Ginger
Rooibos
Lemon balm
Most herbal infusions do not naturally contain caffeine, although the caffeine content depends on the ingredients used.
Rooibos, for example, comes from a different plant and is naturally caffeine-free.
What Is the Difference Between Tea Types?
The biggest difference between the main true tea categories is how the leaves are processed.
Type | Main Processing Characteristic | Typical Flavor Profile |
Black tea | Highly oxidized | Bold, malty, rich |
Green tea | Minimally oxidized | Fresh, vegetal, grassy |
Oolong tea | Partially oxidized | Floral, fruity, roasted |
White tea | Lightly processed | Delicate, subtle, sweet |
Yellow tea | Includes yellowing stage | Mild, smooth |
Dark tea | Post-fermented or aged styles | Earthy, mellow |
Herbal tea | Made from other plants | Varies by ingredient |
The exact flavor depends on the tea cultivar, growing region, harvest, processing method, storage, and brewing method.
Which Types of Tea Contain Caffeine?
Black, green, white, and oolong teas naturally contain caffeine because they come from Camellia sinensis.
The amount can vary considerably between products and serving sizes.
The FDA gives typical caffeine figures of about 71 mg for a 12-ounce black tea and 37 mg for a 12-ounce green tea, while also noting that caffeine levels vary by product and container size.
Herbal infusions made without Camellia sinensis are generally caffeine-free, but you should check the ingredients when caffeine matters.
If you are preparing tea for a commercial menu, use the supplier's product information rather than assuming that every tea in a category contains the same amount of caffeine.
Which Type of Tea Is Best for Bubble Tea?
There is no single best tea for every bubble tea recipe.
The right choice depends on the flavor and drink you want to create.
Black Tea for Milk Tea
Black tea is a popular choice for milk tea because its stronger flavor works well with milk, creamer, and sweeteners.
Taiwanese black tea, Assam, and Ceylon can each create different flavor profiles.
Green Tea for Fruit Tea
Green tea can work well with fruit flavors because its lighter character can complement ingredients such as strawberry, mango, peach, or passion fruit.
Jasmine green tea is another option when you want a floral note.
Oolong for More Complex Drinks
Oolong can provide a more layered flavor than a simple black or green tea.
Roasted oolong can work particularly well in drinks where you want a deeper tea character.
Tea Bags for Convenience
Tea bags can be useful for businesses that want convenient and consistent preparation.
YIOUYI offers Oolong Tea Bag, Green Tea Bag, and Black Tea Bag options for beverage preparation.
How Do You Choose the Right Tea?
Start with the drink you want to make.
For a classic milk tea, consider a black tea with enough flavor to work with milk and sweeteners.
For fruit tea, green tea or a lighter tea may provide a suitable base.
For a roasted or deeper flavor, consider oolong.
You should also consider:
Flavor strength
Aroma
Tea origin
Leaf grade
Brewing method
Serving size
Hot or cold preparation
Compatibility with milk
Compatibility with fruit flavors
Cost per serving
Consistency for commercial production
For businesses, testing the tea in the finished drink is especially important. A tea that tastes excellent on its own may perform differently when combined with milk, fruit syrup, powders, or toppings.
Loose Leaf Tea vs. Tea Bags
Both formats can be useful.
Loose Leaf Tea
Loose leaf tea allows the leaves to expand during brewing and gives the brewer more control over the amount of tea used.
It can be a good option for businesses that want to adjust strength and develop specific recipes.
Tea Bags
Tea bags are convenient and can simplify preparation.
They can also help with portion control and consistent service when the same amount of tea is needed for each serving.
The best format depends on your equipment, recipe, service volume, and preparation process.
What Are the Most Popular Types of Tea?
Black tea and green tea are widely consumed around the world, while oolong and white tea have strong followings among tea drinkers who enjoy their distinct flavors.
Herbal infusions are also popular because they offer a wide range of flavors and ingredients.
Popularity can vary by country and beverage category, so there is no universal ranking that applies to every market.
For a bubble tea business, the most useful tea is often the one that works consistently with the drinks on the menu.
Tea for Cafés and Bubble Tea Shops
Choosing tea for commercial use involves more than selecting a flavor.
A café or bubble tea shop needs to consider consistency, supply, brewing requirements, recipe compatibility, and cost.
A tea supplier can help businesses compare different tea leaves and formats based on their intended applications.

Frequently Asked Questions About Types of Tea
How many types of tea are there?
There are several major categories of true tea, including black, green, oolong, white, yellow, and dark tea. Herbal infusions are often called tea but are not technically made from the tea plant.
What are the 5 main types of tea?
Many consumer tea guides group the main types as black, green, white, oolong, and herbal tea. However, herbal tea is technically a tisane rather than true tea. More detailed tea classifications also include yellow and dark tea.
What is the difference between black tea and green tea?
Both come from Camellia sinensis, but they undergo different processing. Black tea undergoes substantial oxidation, while green tea is processed to limit oxidation. This produces differences in flavor, color, and aroma.
Is oolong tea black or green tea?
Oolong is its own tea category. It comes from Camellia sinensis and is partially oxidized, placing its processing between many green and black tea styles.
Is herbal tea real tea?
In the strict botanical sense, herbal tea is not true tea. Herbal infusions are made from plants other than Camellia sinensis.
Which tea has the most caffeine?
Caffeine levels vary by product, leaf, preparation method, and serving size. You should not assume that one tea category always contains the most caffeine.
Which tea is best for milk tea?
Black tea is a common choice for milk tea because its stronger flavor pairs well with milk and sweeteners. However, oolong and other teas can also be used depending on the desired flavor.
Which tea is best for fruit tea?
Green tea is commonly used as a fruit-tea base because its lighter flavor can work well with fruit ingredients. Jasmine green tea and some oolong teas can also work depending on the recipe.
Final Thoughts
The world of tea includes far more than black and green tea. Black, green, oolong, white, yellow, and dark teas all come from Camellia sinensis but differ in processing and flavor. Herbal infusions form another broad category made from other plants.
For home drinkers, the best way to explore different types of tea is to compare their aroma, flavor, body, and brewing style.
For cafés and bubble tea businesses, the choice should also consider how each tea performs in the finished drink.
