Is a glass or thermal carafe better?
Although pricier, we always suggest buying coffee makers with a thermal carafe. Thermal carafes are not only sturdier than glass carafes but also do a better job of preserving the coffee's flavor, in addition to its temperature. For a glass carafe to maintain coffee's temperature, it needs to be on a warming plate. However, since the warming plate also continues to "cook" the coffee, it will eventually start to negatively impact the flavor and quality of the coffee.
