It also is able to hold up to fifty ounces of coffee, which is enough for ten cups. This allows the user to serve large amounts of guests at a time. The Bunn STX uses an internal thermostat, which keeps the water at an ideal brewing temperature, which allows for the coffee to taste fresh. When compared to another coffee maker by Bunn, the NHBX, the STX has several advantages in that it does not require a warming pad, and has a double wall thermal carafe.
