WHAT IT DOES: The manual-adjust stop on the KBT's brew basket allows you to control the brewing speed or stop it entirely as it flows into the carafe. The borosilicate glass lining of the stainless steel carafe retains heat and keeps your coffee hotter longer. WHY WE LOVE IT: This brewer is a good option for those who like to be more hands-on with their coffee brewing process and don't consistently brew a full carafe every day.
