I have the old white carafe and it never seems to keep my coffee warm for long. I have filled the carafe with hot water first, but that still does not help. Does the Chrome Carafe keep beverages hotter longer?
I never had the white one, but the current one keeps things hot FOREVER. I have had coffee out of it the next day!
I found that, while the newer one keeps things warmer longer, it's by about 25% longer. If your white one isn't working, try filling it with really hot water when you start your coffee pot. Then pour it out right before you fill it with coffee. That 10 minutes sit time will be far more effective than a 30-second swish.
