Bubble tea — also known as boba tea, pearl milk tea or QQ tea — originated in Taiwan in the 1980s and has since become one of the most popular drinks in the world. Making it at home is easier than you might think, and once you know the basics you can experiment endlessly. This guide covers everything from tapioca pearls to popping boba.
What is bubble tea?
Bubble tea is a chilled drink made from a base of tea (most commonly black, green or oolong), combined with milk or fruit flavourings, sweetened with syrup, and served over ice with chewy tapioca pearls at the bottom. The "bubbles" in the name originally referred to the froth created by shaking the drink, though most people now associate it with the pearls.
What you need to make bubble tea
- Tea — black tea is the classic base. Oolong, green and jasmine all work well. Loose leaf or good-quality teabags.
- Tapioca pearls — black tapioca pearls, made from cassava starch, are the traditional topping. Cook them fresh each time.
- Brown sugar syrup — the sweetener that coats the pearls and flavours the drink. Easy to make yourself (recipe below).
- Milk — full-fat gives the richest result. Oat, almond and condensed milk all work well.
- Ice — plenty of it. Bubble tea is always served cold and well chilled.
- Wide straws — essential. Standard straws are too narrow for the pearls to pass through.
You do not need any specialist equipment beyond a wide straw and something to shake the drink in. A cocktail shaker or a jar with a tight-fitting lid works perfectly.

This is the most important step to get right. Poorly cooked pearls are either hard in the middle or mushy — follow these steps for a properly chewy texture.
- Boil a large pan of water. Use far more water than you think you need — at least 10 parts water to 1 part pearls. Tapioca expands significantly and needs space to move freely.
- Add the pearls at a rolling boil. Drop them in and stir immediately to stop them sticking, then reduce to a medium boil.
- Cook for the time on the packet. Typically 10 to 15 minutes, but this varies by brand and pearl size. Overcooking makes them mushy; undercooking leaves them hard in the centre.
- Drain and transfer to syrup immediately. Drain through a sieve and tip the hot pearls straight into a bowl of brown sugar syrup — the heat helps them absorb it. Leave for at least 10 minutes.
- Use within 2–4 hours. Tapioca pearls harden quickly as they cool and cannot be reheated successfully. Cook only what you need.
Brown sugar syrup — quick recipe: combine 100g dark brown sugar with 100ml water in a small saucepan. Heat over medium heat, stirring, until the sugar dissolves completely. Simmer for 3 minutes until slightly thickened, then cool.
Classic milk bubble tea — step by step
- Brew a strong pot of tea. Use twice as much tea as you normally would — the ice and milk will dilute it significantly. Brew for 5 minutes, then cool completely (the fridge speeds this up).
- Cook and sweeten your tapioca pearls. Follow the steps above. While the pearls soak in syrup, prepare the rest of the drink.
- Combine tea, milk, syrup and ice in a shaker. Add 150ml of cold brewed tea, 80ml of milk, 2–3 tablespoons of brown sugar syrup and a large handful of ice. Shake vigorously for 20–30 seconds — that's what creates the frothy top.
- Assemble. Spoon the pearls into the bottom of a tall glass. Pour the shaken tea and milk over, including the ice. Add a wide straw and serve immediately.

Brew the tea strong. Weak tea disappears behind the milk and ice. Double the amount you would normally use and brew for longer.
Cool everything before assembling. Warm tea melts the ice instantly and leaves you with a watery drink. Brew in advance and refrigerate.
Shake hard. The frothy layer on a good bubble tea comes from vigorous shaking. Thirty seconds makes a noticeable difference.
Adjust the sweetness. Start with less syrup than you think you need. You can always add more; you cannot take it away.
Bubble tea FAQs
What do I need to make bubble tea at home?
Tea (black, green or oolong), tapioca pearls, brown sugar syrup, milk or a dairy-free alternative, ice, and wide straws. No specialist equipment is required — a jar with a lid works as a shaker.
How do you cook tapioca pearls for bubble tea?
Boil them in a large pan of water, following the packet timing (usually 10–15 minutes), then drain and transfer straight into brown sugar syrup while still hot. Use within 2–4 hours — they harden as they cool.
What is the difference between tapioca pearls and popping boba?
Tapioca pearls are chewy, dense spheres that absorb the flavour of the syrup they soak in. Popping boba are small gel spheres filled with flavoured juice that burst when bitten. Tapioca is the classic; popping boba suits fruit tea drinks better.
Can I make bubble tea without a shaker?
Yes. A jar with a tight-fitting lid works perfectly. Fill it no more than two-thirds full so the liquid can move freely.
How long do cooked tapioca pearls last?
Best used within 2–4 hours. They harden significantly as they cool and cannot be successfully reheated or stored overnight. Cook only what you need.
