What is bubble tea: FAQs

  • What exactly is bubble tea?

    Bubble tea is a drink made popular in Taiwan. Typically containing a tea base, bubble tea is often topped up with milk and then a whole variety of toppings, including tapioca balls and even grass jelly. If you fancy something different, bubble tea can also be made with fruit juice or coffee.

  • What's the difference between boba tea and bubble tea?

    Boba tea is a variation of bubble tea. Boba are little pearls full of juice, such as honeydew or lychee, that can be added to your bubble tea. Boba pearls pop as you chew them, releasing extra fruity flavors.

  • What is the origin of bubble tea?

    Bubble tea, also known as pearl milk tea or boba tea, originated in Taiwan in the 1980s. The specific origin story of bubble tea is attributed to a tea house called Chun Shui Tang, located in Taichung, Taiwan. In the 1990s, bubble tea started to gain international recognition and spread to other parts of the world, including the United States, Canada, and various countries in Europe.

  • What are the ingredients in bubble tea?

    Bubble tea is a beverage that usually contains tea (black, green, or oolong), sweeteners (such as sugar, syrup, or sweetened condensed milk), milk or non-dairy alternatives, and tapioca pearls (also known as boba). Other optional ingredients may include fruit syrups, fruit jelly, grass jelly, or popping boba.

If your idea of a perfect cup of tea usually involves a tea bag or some tea leaves brewed in a pot and served with a healthy dose of milk and sugar in your favorite mug, then you may not have sampled all that bubble tea has to offer. The popular drink enjoyed across Asia since the 80s can be served hot or cold. While it is traditionally made with tea and milk, it can also include some fruit or fruit juice before being thoroughly blended and topped up with some tapioca pearls and extra goodies.

There are even versions of the drink that don’t include tea and are instead made with taro milk, strawberry milk, or even coffee. While these aren’t technically bubble tea, they’re still pretty refreshing! 

So, is it just a fancy tea?

Given that it has tea as its base, you’d be forgiven for thinking bubble tea (also known as boba milk tea or pearl milk tea) is just a dressed-up version of tea, yet the drink itself is actually quite unique. While bubble tea usually begins with some well-brewed tea, it also contains added extras that you wouldn’t expect to find.

Some popular varieties of tea used in bubble tea include black tea, green tea, Assam, oolong tea, and even Earl Grey. The bit that makes bubble tea special is adding tea flavors and toppings that can be tailored to suit your personal taste. 

Add a little flavor

One of the most popular additions to a good cup of bubble tea are chewy tapioca pearls. These little balls of goodness are made from cassava roots and are often spooned into the cup to add a bit of a bite to your beverage. If you’re feeling adventurous, try some grass jelly, a traditional sweet and chewy jelly cube found in Asian desserts. Popping boba is also a staple of the bubble tea drink. As their name suggests, these are little balls filled with fruit flavors such as lychee, honeydew, and passionfruit that pop as you chew them. 

Is milk added to bubble tea?

In many versions of the drink, yes, it is. Classic bubble tea uses whole milk for added creaminess, but any milk could be added to suit your tastes and health requirements. Soy milk is a popular addition, as is oat milk, almond milk, and even condensed milk if you’re looking for that extra sweetness. If none of these options sound good, then a creamer can be added to give you that milky hit. But fear not, if you don’t like milk or you can’t drink it for health reasons, there are plenty of boba drink options that don’t include it at all. We’ll look at these later when we explore some tasty recipes you can try at home. 

All things sweet

Along with milk, traditional Taiwanese versions of bubble tea often contain some added sweetness. Depending on your preference, this can be white sugar, brown sugar, sweetener, or even simple syrup. If your drink has a fruit tea base that’s already sweet to begin with, then the level of added sugar can be adjusted to your preference. And, of course, if added sweetness isn’t your thing, it can be entirely left out. So, with all this sweetness in mind, you may wonder just how healthy bubble tea is. Read on to find out…

Is bubble tea a healthy choice?

As with many food and drink choices, bubble tea can be as healthy or not quite as healthy as you choose. Making it yourself means you have more control over the quality and quantity of the ingredients. Still, as with most things, moderation is key, and if the odd cup from your favorite bubble tea shop is something you enjoy as an occasional treat, then go for it! That being said, let’s explore how you can ensure your bubble tea is as healthy as it can be, starting with the potentially not-so-good ingredients. 

Palm oil

Some shop-bought bubble teas contain hydrogenated palm oil which isn’t great for you or the environment. Making your tea at home means you can do your best to entirely skip this ingredient, reducing the calories and doing your bit for the planet all at the same time. 

Artificial sweeteners

Sweeteners can be a good way to reduce your sugar intake, and there are some great naturally derived choices out there, but it’s the artificial sweeteners that are the ones to avoid. Some contain potentially harmful chemicals, which, let’s face it, we could all do without. 

Saturated fats 

Many bubble teas use condensed milk and whole milk, which, if consumed every day, can become calorific. A little of what you fancy does you good, but consider occasionally switching the heavier milk for some lighter options, such as skimmed milk or even oat or soy milk. 

Now we’ve looked at the potentially less healthy ingredients, let’s look at some of the things that make bubble tea a good choice next time you need a little refreshment.

Hydration, hydration, hydration

When made well, bubble tea can be an excellent option for keeping up those hydration levels. With a tea base and added milk, a cup of bubble tea can be a tasty way to help you reach that recommended guideline of six to eight cups of water daily. 

Make mine a matcha

With a seemingly endless choice of teas available, your bubble tea can be tailored to your tastes, and it doesn’t have to include milk or sugar at all, making it really rather healthy. If green tea is your choice, matcha bubble tea can make a great alternative to the traditional drink. Just think of all those lovely antioxidants.

Good for gluten-free

Good news for those who follow a gluten-free diet, plain bubble tea should be gluten-free. That’s because the tapioca balls used in the drink are made from tapioca starch which is safe for those who just don’t get on with gluten. That being said, it’s always a good idea to check before you enjoy your tea, as not all added bubble tea toppings will be gluten-free. 


No, this heading doesn’t refer to how many bubble teas you should drink in a day (though you could if you wanted, we won’t tell). In a healthier version of bubble tea, fruit and fruit puree can be added to your drink, meaning your bubble tea is helping you on your way to those all-important five pieces a day of fruit and veg.

Bubble tea recipes

So, now that we’ve explored bubble tea in some detail let’s turn our attention to some tasty bubble tea recipes so that you can learn how to make this bubbly beverage at home. The first thing to decide before you dive in with those toppings is whether you want your bubble tea to be warm or cold. 

Warm tea

Like any good cup of tea, starting with warm water is a popular way of making bubble tea at home. Here are some useful things to keep in mind to ensure a delicious drink:

  • For Earl Grey or Assam teas, the optimum water temperature to avoid loss of taste should be 98° Celsius (208° Fahrenheit)
  • Let your boiling water cool a little before pouring it over tea bags or leaves
  • Allow the tea to steep for five minutes before straining. 

Cold tea

If iced tea is more up your street, you’ll want to begin with a cold water base for your bubble tea. This method is a little different and can be done by:

  • Place your tea bags or leaves in a large jug that will fit inside your fridge
  • Fill the jug and allow your tea to steep for up to twelve hours
  • Once the brewing time is up, strain out the tea bags or leaves, and your tea is ready.

Once your base is ready to go, it’s time to make your perfect bubble tea. Let’s begin with a recipe for a traditional version, starting with a warm tea chilled with ice. 

Traditional bubble tea 

  • Make a batch of warm tea and allow it to cool slightly
  • Stir some caster sugar with 60ml of water over medium heat to make a clear sugar syrup. Allow to cool.
  • Add some quick-cook tapioca balls (these can be bought online or from Amazon) to 500ml of water. Allow it to reach a rolling boil. 
  • After 2-4 minutes, strain the balls in a sieve, cooling slightly. Add to a mixing bowl with 1 tsp of dark brown sugar and mix. 
  • Make a dark syrup by mixing 50g of brown sugar with 60ml of water. Bring to a boil, then allow to cool. Add the boba and thoroughly coat. 
  • Add the boba into a glass, swirling to coat. Pour in some of the tea and 1 tbsp of clear sugar syrup. Add some ice. Top up with cold milk and serve with a boba straw.
