Brew big or small with the flexible Keurig K500 (pictures)

The most flexible Keurig coffee machine yet, the K500 uses pre-packaged cups to brew either big carafes or small single servings.

A large LCD screen shows brewing details.

Like Keurig's other machines, the K500 opens up to accept pre-made coffee packets.

The K500 comes with a carafe that holds 30 ounces of coffee.

Inside the K500 is a large 80 ounce water reservoir.

As part of the Keurig system, the K500 has over 250 flavors of coffees and teas at its disposal.

Select between 2 or 30 ounces.

To brew a whole carafe, the K500 needs to use a bigger coffee cup package.

Here's the Keurig K500 in action.
