Warmer weather in the United States often means iced tea, sweet tea, and another tea-based drink that continues to grow in popularity both in North America and Europe: bubble tea. Depending on where you are, you may also hear it called pearl milk tea or boba tea. Having spent many years as a technical writer—where the difference between “hit Enter” and “press the Enter key” genuinely mattered—I can’t resist taking a closer look at these names. So sit back, relax, sip your tea, and join me for a brief linguistic adventure.

Bubble Tea or Pearl Milk Tea?
Let’s start with the word bubble. A bubble is generally a thin film surrounding air or gas, creating a spherical shape. Soap bubbles, chewing gum bubbles, carbonation bubbles, and even the tiny bubbles that appear on freshly poured tea all fit this description.
For a formal explanation, see this dictionary definition of a bubble. (I’ve simplified things a bit for our discussion.)
A pearl, by contrast, is a solid object. True pearls are created by mollusks and are valued for their smooth, lustrous appearance. The term is often applied more broadly to small, round objects because it sounds more elegant than calling them spheres or balls.
After all, which sounds more appealing: “Dragon Spheres Tea” or “Dragon Pearls Tea”? Marketing professionals understand that word choice matters.
Based purely on the definitions, “pearl milk tea” might seem like the more technically accurate name. But the story doesn’t end there.
Where Did the Name Bubble Tea Come From?
One popular theory is that “bubble tea” evolved from the Taiwanese term boba. Others suggest the name comes from the frothy bubbles created when the drink is vigorously shaken during preparation. It’s also possible that translation choices helped popularize the term as the beverage spread internationally.
Languages rarely translate perfectly from one culture to another. Words that appear similar may carry different shades of meaning, and translators often choose the closest available term. As a result, both “bubble tea” and “pearl milk tea” became widely accepted names for the same family of drinks.
So which is correct? Probably both.
What Are the “Bubbles” in Bubble Tea?
The answer is surprisingly simple: they’re usually tapioca pearls.
These chewy spheres are made from tapioca starch, which comes from the cassava plant (Manihot esculenta). Cassava originated in South America and eventually spread throughout tropical regions of the world through trade and cultivation.
Taiwanese tea vendors later incorporated tapioca pearls into tea drinks, creating what would become modern bubble tea. Traditional versions commonly featured black tea combined with milk, ice, and tapioca pearls, though countless variations now exist.
Today, you can find bubble tea made with black tea, green tea, oolong tea, fruit teas, flavored syrups, and a wide variety of toppings beyond the classic tapioca pearls.

Bubble Tea’s Growing Popularity
As bubble tea became more widely available, green tea versions gained popularity alongside traditional black tea recipes. Fruit-infused versions, smoothie-style preparations, and creative specialty drinks have further expanded the category.
The result is a beverage that combines tea, dessert, and a unique texture experience in a single cup.
If you’ve never tried it, warm weather is a great excuse to give bubble tea a chance. In many ways, it’s reminiscent of drinkable tapioca pudding—with tea as the star ingredient.
Now that’s an interesting combination.
