How to make an americano ?


assistant
The classical Americano needs a specific ratio between coffee and water: 2 parts of water and 1 part of expresso. 
Ideally, you can use coffee beans and grind them just before you brew.
With a coffee machine: make one shot of expresso in a mug and fill it to the top with additional hot water at 60 degrees Celsius.
