The House Standard
Not a name.
A specification.
21Grams takes its name from the exact mass of ground coffee in a double shot. The interface is black and white. The rooms are not. The recipe never guesses.
01
Dose
21 grams of coffee. Never 18. Never 20. The double shot is a specification, not a suggestion.
02
Ratio
Every drink on the board is written in ounces. Milk, water, and espresso, measured, not guessed.
03
Finish
No syrups. No seasonal theatre. A cup that can be reproduced tomorrow to the same gram.
