I make a pot in the morning, an old Revere Drip-O-Lator. Makes 8, 5-1/2 oz. cups. Little less than a quart and a half. I also have an airpot, all stainless Zojirushi pump job. Indestructible. But what I usually use is a Silex glass candle warmer. Takes a tea light and keeps my coffee just right most of the day.
