I haven't checked my brewing temp for years but I meant to, just keep forgetting. Maybe I'll set the thermometer on top so I remember.
I have a little trick for when I'm making just one "cup" (~20 oz): I'll fill the basket with 2 scoops (2 T I think), fill the water reservoir to ~3.5 on the water level gauge, turn it on & set my timer for >5 minutes and let it brew without the carafe in place.
The water almost completely fills the basket & just sits there, kind of french press style. After enough time I'll stick the carafe under there without the lid and press the pause & serve button spring w/ the carafe's edge while filling it. (it'll flow too fast & overflow the carafe if the lid is on when you do it like this)
makes a good 'single' refill cup.
