'Instant coffee' literally breaks down as 'speedy-dissolving coffee': 速 (sù) means 'fast' or 'quick'; 溶 (róng) means 'to dissolve'; and 咖啡 (kāfēi) is the loanword for 'coffee'. Together, 速溶咖啡 refers to powdered or granulated coffee that dissolves instantly in hot water—no brewing equipment needed. It’s a staple in Chinese offices, dormitories, and homes where convenience trumps traditional preparation.

This term is neutral and widely understood across all age groups. Unlike traditional brewed coffee, 速溶咖啡 often contains added sugar, creamer, or flavorings—though plain versions are also available. It’s commonly sold in single-serve sachets or jars, and frequently appears in advertising emphasizing time-saving and modern lifestyle.
