Does Boba Tea Have Caffeine & How Much Is In It: Comparison

Bubble tea has become one of the most popular drinks worldwide. From its birthplace, Taiwan, to Las Vegas, from Tokyo to Boston, everyone loves these chewy boba pearls and endless flavor choices. But many people wonder: Does boba milk tea have caffeine? If you’re curious about how much caffeine is in your favorite drink or whether caffeine-free options exist, this guide is for you.

Does Bubble Tea Have Caffeine?

Yes, most bubble tea contains caffeine. This is because the drink is usually made with a brewed tea base such as black, green, or oolong tea, which all naturally contain caffeine.

On the other hand, the iconic tapioca pearls (a.k.a. boba) that add a fun, chewy texture to Taiwanese bubble tea are made from cassava root, so they are completely caffeine-free.

How Much Caffeine is in Bubble Tea: Comparing Common Boba Types and Their Caffeine Levels

Here is a breakdown of how much caffeine is in black tea, green tea, oolong tea, matcha, fruit tea, and coffee boba drinks, so you know what to expect from your next sip.

Caffeine in Black Tea Boba

Black tea is the most common base for classic milk tea and tends to have the highest caffeine among standard boba options. An 8-ounce cup of black tea contains around 50-90 mg of caffeine, depending on the variety and brewing strength. Assam black tea, for example, often sits at the higher end of that range.

Caffeine in Green Tea Boba

Green tea-based boba is lighter and fresher in taste, with a moderate caffeine kick. A standard 8-ounce serving contains roughly 25-35 mg of caffeine. While it has less caffeine than black tea, it’s still enough to provide a mild energy boost, making it a balanced option for those who want something gentler.

Caffeine in Oolong Tea Boba

Oolong tea strikes a middle ground between black and green tea in both flavor and caffeine content. An average cup of oolong-based boba contains about 30-50 mg of caffeine. This makes it a good choice for drinkers who want something smooth and aromatic without going too heavy on caffeine.

Caffeine in Matcha Boba

Matcha milk tea is made with powdered green tea leaves, which makes it more concentrated. An 8-ounce serving typically contains 60-70 mg of caffeine, but it can go higher if prepared differently. With its natural antioxidants, matcha also offers a steadier, more focused energy release, making people less likely to crash out after the caffeine has run its course.

Caffeine in Fruit Tea Boba

Fruit teas can be a bit more complex. If your fruit tea is made with a black or green tea base and combined with fruit puree or syrup, it will contain a similar amount of caffeine to its tea base, though sometimes slightly less (around 30-40 mg) due to dilution.

However, when prepared with herbal teas or just fruit syrup and water, the caffeine content drops to zero. This makes fruit teas a great caffeine-free treat for kids or anyone avoiding stimulants.

Caffeine in Coffee Boba

Some shops offer coffee as a base for boba drinks. In this case, caffeine levels are much higher, averaging 90-100 mg per 8-ounce cup. That said, coffee boba is the strongest option and best suited for those who want a real pick-me-up for starting their day or powering through a long afternoon.

Caffeine in Milk Tea vs Coffee and Energy Drinks: Which is Stronger?

Bubble tea typically contains much less caffeine than coffee or energy drinks. A standard cup of black milk tea has around 50-90 mg of caffeine, while an equivalent serving of coffee often ranges between 150-200 mg. Energy drinks can vary by specific products, with most reaching 300 mg per 16-ounce can, which makes it over 150 mg per cup.

Because of this difference, bubble tea is considered a gentler source of caffeine than a cup of joe or an energy drink. It delivers a light boost without the intense jolt or potential jitters that can come with stronger beverages. Thus, if you’re looking for a sweet spot between flavor and energy, bubble tea offers the perfect balance.

What Affects the Level of Caffeine in Bubble Tea?

The caffeine level in bubble tea depends on how it’s prepared, so you will have to consider the type of tea or base, the tea-to-water ratio, the brewing temperature, and steeping time.

Type of Tea or Base

The kind of tea you choose makes the biggest difference. As mentioned, black tea generally has the highest caffeine content (50-90 mg per cup), while green tea contains a bit less (25-35 mg). Oolong falls somewhere in between, and herbal or fruit bases often have little to no caffeine.

Tea-to-Water Ratio

The more tea leaves or powder you use, the stronger the brew and the higher the caffeine. A concentrated ratio will release more caffeine into the drink, while using fewer leaves or more water will dilute the caffeine level.

Brewing Temperature

Hotter water extracts caffeine more quickly. This is why steeping tea at higher temperatures usually produces a bolder, more caffeinated brew. Still, going beyond the recommended range can also pull out bitter flavors, so balance is key.

Steeping Time

The longer you steep the tea leaves, the more caffeine is released into the water. A quick steep of 1-2 minutes may yield a lighter drink with less caffeine, while a longer steep of 3-5 minutes will result in a stronger, more energizing cup.

Though boba shops usually follow consistent recipes, those making bubble tea at home have more control. This makes it important to understand these factors when preparing homemade bubble tea, especially if you’re experimenting with different flavor combinations.

Can You Get Bubble Tea Without Caffeine?

Absolutely! While many bubble teas are tea-based, there are plenty of delicious and refreshing options for you to enjoy the boba experience without the caffeine.

Whether you are ordering for a child, sensitive to caffeine, or just prefer to avoid it, here are some of the best bubble tea flavors you can try:

• Milk Bobas: These creamy, comforting drinks are made with milk and other flavorings like syrups or powders, completely omitting a tea base. Popular examples include Brown Sugar Milk, which features a caramelized sweetness, and Taro Milk, known for its nutty, vanilla-like flavor and vibrant purple color.

• Fruit Bobas: Refreshing choices like mango, strawberry, or lychee can be prepared without tea by using fruit flavoring with a water or milk base. This makes them sweet, fruity, and completely caffeine-free.

• Herbal Tea Bobas: Some shops offer herbal infusions such as osmanthus, hibiscus, chamomile, or mint. These are caffeine-free while still providing unique, fragrant flavors.

• Smoothies: Fruit smoothies with boba are another fun alternative. These are blended drinks made from fresh or frozen fruit, ice, and sometimes milk or yogurt, making them a delicious and caffeine-free treat.
