If you want to make a large amount of coffee in one go, the Krups Double KM8508 is the coffee machine for you. You'll get 2 coffee filters in one device, so you can easily brew 21 cups of coffee (of 120ml) in one go using the 2 pots. Handy for a birthday if you have a large family or for at the office if you often have to serve large groups. Are there any tea-lovers? That won't be a problem. You can easily brew one pot of coffee and make one pot of tea, as the coffee machine includes a separate filter that you can use to make tea. The pots can also be used separately if you don't have many people coming over for a chance.
