NOT JUST COFFEE,
WE BREW A CULTURE.
A specialty coffee house in the heart of Sài Gòn — where Vietnamese heritage meets world-class precision, and every cup is an act of culture.
GRANDMUM is the creation of Thi — Vietnam's first Aeropress Champion. Trained through competition and shaped by a love for her country's coffee culture, she opened GRANDMUM to prove one thing: Vietnamese specialty coffee deserves its place on the world stage.
The name is warmth, precision, and quiet authority. Like a grandmother who brews without measuring — because she already knows.
