The origin of pearl milk tea:

In the early days, there was only one name. Around 1988, a vendor called "Grasshopper" on Hai'an Road in Tainan City renamed pearl milk tea Boba milk tea after taking inspiration from the then actress Ye Zimei. Later, in southern Taiwan, the saying that boba refers to large pink circles and pearls refers to small pink circles gradually emerged. As chain stores in southern Taiwan expand to northern Taiwan, this classification is gradually accepted by Taiwanese residents.

Outside of Taiwan, the term "BOBA" or "Bubble" is also commonly used. The reason is that the new Taiwanese immigrants to North America in the late 1980s still used "Boba Milk Tea" as a motto. Therefore, "BOBA Tea House", "BOBA Planet", "BOBA World" and other tea shops have sprung up all over California. Now it is very popular. Taiwanese residents still say "BOBA" or "Bubble" all the time.

They will say to the waiter at the counter in English: "Give me latte, and add some BOBA in, please." It has become synonymous with pink balls.

Bubble milk tea generally uses larger-sized powder balls, and the diameter after cooking is about 7 mm or more. Otherwise, if the diameter is too small, it will be easy to fill your mouth with pearls, and it will be inconvenient to swallow and chew. But most bubble tea merchants still provide small pink and round pearls. Of course, there is also a kind of "amber pearl" which is made of 100% brown sugar.
