What Is Bubble Tea? A Beginner’s Guide (Plus FAQs Answered)

You’ve probably seen people walking around with colorful drinks filled with chewy pearls and oversized straws. That’s bubble tea—also known as boba tea, pearl milk tea, or 珍珠奶茶 (zhēnzhū nǎichá). But what exactly is it, and why has it taken the world by storm? Let’s break it down.


What Is Bubble Tea?

Bubble tea is a tea-based drink from Taiwan that typically includes:

  • A base of black, green, or oolong tea
  • Milk or fruit flavorings
  • Sweetener
  • Tapioca pearls (boba) or other toppings like jelly, pudding, or popping boba

It’s served in a clear cup with a sealed lid and a wide straw that lets you sip both the drink and the chewy toppings at the same time.


Why Is It Called “Bubble Tea”?

The name “bubble tea” comes from two things:

  1. The frothy bubbles created when the drink is shaken.
  2. The tapioca pearls, which look like bubbles sitting at the bottom of the cup.

These days, most people associate the name with the pearls themselves.


The Famous Tapioca Pearls (Boba)

The chewy “bubbles” are made from tapioca starch, derived from the cassava root. When cooked, they become soft, bouncy, and slightly sweet. Variations include:

  • Classic black pearls
  • Mini pearls (smaller and softer)
  • Crystal boba (clear and jelly-like)
  • Popping boba (fruit juice-filled spheres that burst in your mouth)

Popular Bubble Tea Flavors

Bubble tea is endlessly customizable. Some favorites include:

  • Classic milk tea (black tea + milk + pearls)
  • Brown sugar milk tea (sweet, caramel-like stripes)
  • Taro milk tea (purple, nutty, vanilla-like flavor)
  • Matcha green tea (earthy and rich)
  • Fruit teas (mango, lychee, peach, passionfruit, and more)

Bubble Tea FAQ

1. Is Bubble Tea Healthy?

It depends on how it’s made. Traditional bubble tea is often high in sugar and calories, especially with flavored syrups and sweetened pearls. That said, you can make it healthier by:

  • Choosing less sugar (most shops let you adjust sweetness levels)
  • Opting for fruit teas without milk
  • Skipping high-calorie toppings like pudding or cream

Like most treats, bubble tea is best enjoyed in moderation.


2. Does Bubble Tea Have Caffeine?

Yes—most bubble tea contains caffeine, since it’s made with tea (usually black, green, or oolong). A standard cup can have anywhere from 30–70 mg of caffeine, depending on the tea base and serving size. However, you can also order decaf or herbal versions at many shops.


3. What Do Tapioca Pearls Taste Like?

Tapioca pearls themselves are fairly neutral, with a mild sweetness and chewy texture. They absorb the flavor of the drink, which makes them pair perfectly with milk tea or fruit tea.


4. Is Bubble Tea Dairy-Free?

Not always, but it can be! Many shops offer non-dairy milk options like almond, oat, or soy milk. Fruit teas are usually dairy-free by default.


5. Why Do Bubble Tea Cups Have Big Straws?

The wide straw is designed so you can sip up the pearls and toppings along with the tea. It’s part of what makes drinking bubble tea such a fun, interactive experience.


Final Sip

Bubble tea is more than just a drink—it’s a playful, customizable experience that blends tea, flavor, and texture in one cup. Whether you prefer a classic milk tea, a fruity blend, or something wild like cheese foam topping, there’s a bubble tea for everyone.
