Many of the thermal coffee makers that we`ve reviewed here come with brewing options that allow you to make a smaller pot of coffee rather than a full pot. For some of them, you would just use less water and coffee grounds while others let you fill up the water tank, add your grounds, and select the amount of coffee you want the machine to make. This allows to make the perfect amount of coffee for just one or two people to drink instead of throwing away extra cups no one wants.
