‘啤酒’ (pí jiǔ) is the standard Mandarin term for 'beer' — an alcoholic beverage made from fermented grains, typically barley, and flavored with hops. The first character 啤 (pí) is a phonetic loan character derived from the English word 'beer', while the second character 酒 (jiǔ) means 'alcoholic drink' and appears in many beverage names like 白酒 (bái jiǔ, 'baijiu') and 黄酒 (huáng jiǔ, 'yellow rice wine'). Together, they form a compound noun that specifically denotes beer, not other alcoholic drinks.

This word is commonly used in everyday contexts: ordering at restaurants or bars, discussing preferences ('I like light beer'), or referring to social drinking culture. It’s neutral in register — appropriate for both casual conversation and formal settings — and always functions as a countable noun when paired with measure words like '瓶' (bottle) or '杯' (glass). Unlike some food terms, 啤酒 has no strong regional variations in meaning across Mandarin-speaking areas.
