Coffee-Making Tips; Troubleshooting - Bosch TKA?3A Series Instruction Manual

Coffee-making tips

Store ground coffee in a cool place; you
can also freeze it.
Once a package of coffee has been
opened, close it tightly to maintain its
aroma.
How the coffee beans are roasted affects
their taste and aroma.
Darker roast = more flavour
Lighter roast = more acidity
