There are many theories out there - none of which are supported by scientific fact. Keep your coffee in an airtight container in a cool, dark, dry place. It is the simple.
To prepare and serve coffee properly, once again, keep it simple:
- Use fresh water for boiling.
- Once boiled, let the kettle cool for a few minutes, since boiling water burns the coffee (best to pour the water at between 90C to 96C).
- It is always best to put too much coffee in than too little. You can always dilute the coffee if it is too strong. A rough guide is 10 grams of coffee for every 180ml of water.
- Invest in a cafetiere/French press - it is a great way of brewing and serving coffee. Drip/filter coffee is also a good method.
