We've all come across those mysterious airpots filled with coffee -- can you trust them? Is the coffee in them still warm after hanging out for awhile? Should you take the plunge (sorry) or ask for a fresh pot? In order to determine which airpot to carry, we tried out models from Zojirushi, Grindmaster and a misc. Chinese product to see how long they maintained the coffee's temp over a period of several hours. Watch as Gail takes us through features and tests the coffee for temperature stability to determine which model performs best.
