Behmor® Brewer Carafe Plug

The Behmor Brewer has a great carafe, but the way it's designed when it is out of the coffeemaker, it forms a thermosyphon which circulates air in the carafe, cooling off the coffee faster than it should be. Found this out that when I left it in the coffee maker, the coffee stayed hot for 4+ hours, and sitting on the table, it got cold within an hour.

So, that's the reason for the plug. It just drops in and blocks the airflow out of the center of the carafe, keeping your coffee hot and on the table, just like it was intended!
