Bubble tea (also known as pearl milk tea, bubble milk tea, or boba; Chinese: 珍珠奶茶; pinyin: zhēn zhū nǎi chá, 波霸奶茶; bō bà nǎi chá; or 泡泡茶; pào pào chá in Singapore) is a tea-based drink. Originating in Taichung, Taiwan in the early 1980s, it includes chewy tapioca balls ("boba" or "pearls") or a wide range of other toppings.Ice-blended versions are frozen and put into a blender, resulting in a slushy consistency. There are many varieties of the drink with a wide range of flavors. The two most popular varieties are black pearl milk tea and green pearl milk tea.
Brewed coffee is made by pouring hot water onto ground coffee beans, then allowing to brew. There are several methods for doing this, including using a filter, a percolator, and a French press. Terms used for the resulting coffee often reflect the method used, such as drip brewed coffee, filtered coffee, pour-over coffee, immersion brewed coffee, or simply coffee. Water seeps through the ground coffee, absorbing its constituent chemical compounds, and then passes through a filter. The used coffee grounds are retained in the filter, while the brewed coffee is collected in a vessel such as a carafe or pot.
