'啤酒杯' literally combines three characters: '啤' (pí), short for '啤酒' (píjiǔ, 'beer'); '酒' (jiǔ), meaning 'alcoholic beverage'; and '杯' (bēi), meaning 'cup' or 'glass'. Together, it refers specifically to a vessel designed for serving and drinking beer — typically larger, heavier, and often with a handle or thick base compared to regular glasses. It emphasizes function and cultural context: in Chinese bars, restaurants, and home gatherings, this term is used for mugs, steins, or tall pint glasses commonly seen with draft or bottled beer.

The word is neutral in register and widely understood across Mandarin-speaking regions. While '杯子' (bēizi) is the generic word for 'cup', adding '啤酒' specifies purpose and form — implying capacity, durability, and sometimes even style (e.g., frosted, insulated, or branded mugs). It’s frequently used in ordering ('请给我一个啤酒杯'), describing table settings, or discussing beverage service in hospitality contexts.
