Dear Diva:
My coffee machine stays on for several hours, and the coffee’s not so good after a while. How long should coffee stay on a hot plate? from Denise, Calabasas, California

Dear Denise…

Several hours? YUK! That means you are drinking “cooked” coffee, girlfriend! Probably black bitter sludge! Now try brewing as little as possible, one cup at a time, if you can… If you want to brew a pot of coffee, please know that it won’t stay really fresh tasting when heated for more than 20 minutes. MAX. You could pour that freshly brewed pot of coffee into a thermos, or better yet, get a coffee machine that brews directly into a thermos…
