Bubble teas are generally of two distinct types: fruit-flavored teas and milk
teas. However, some shops offer hybrid \"fruit milk teas\". Most milk teas
include powdered dairy or non-dairy creamers, but some shops also offer
fresh milk as an alternative. Other varieties are 100% crushed-fruit smoothies
with tapioca pearls and signature ice cream shakes made from local ice
cream sources. Many American bubble tea vendors sell \"milk smoothies\",
which are similar to bubble tea but do not contain any tea ingredients. Some
small cafés offer sweetener substitutes such as honey, agave, stevia, and
aspartame upon special request.
The oldest known bubble tea consisted of a mixture of hot Taiwanese black
tea, small tapioca pearls (粉圓), condensed milk, and syrup (糖漿) or honey.
Many variations were created, the most common of which is served cold
rather than hot. The tea type is frequently replaced. First was bubble green
tea, which uses jasmine-infused green tea (茉香綠茶) instead of black tea.
Big tapioca pearls (波霸/黑珍珠) were adapted and quickly replaced the small
pearls.[3] Peach or plum flavoring appeared, then more fruit flavors were
added until, in some variations, the tea was removed entirely in favor of real
fruit. These fruit versions sometimes contain colored pearls (and/or \"jelly
cubes\" as in the related drink taho), the color chosen to match whatever fruit
juice is used. Flavors may be added in the form of powder, fruit juice, pulp, or
syrup to hot black or green tea, which is then shaken in a cocktail shaker or
mixed with ice in a blender. Cooked tapioca pearls and other mix-ins (such as
honey, syrup, and sugar) are added at the end.
Today, one can find shops entirely devoted to bubble tea, similar to the juice
bars of the early 1990s. Some cafés use plastic dome-shaped lids, while other
bubble tea bars serve it using a machine to seal the top of the cup with plastic
cellophane. This allows the tea to be shaken in the serving cup and makes it
spill-free until one is ready to drink it. The cellophane is then pierced with an
oversized straw large enough to allow the pearls to pass through.
Today, in Taiwan, it\'s more common for people to refer to the drink as \"pearl
milk tea\" (zhen zhu). \"Pearl milk tea\" is also used by English speakers and
overseas Chinese and Taiwanese speakers, but it is usually called bubble
tea.
