Postum, a substitute for coffee that had no caffeine and was made of wheat bran, wheat molasses, and maltodextrin (from corn) was discontinued by Kraft Foods in 2007 and I was very sad to see it go. Both Postum and Pero (another coffee substitute) had been staples around my LDS (Mormon) home since I was very little. I still have a jar of Postum in the Natural Coffee Flavor in my pantry that I have been keeping (apparently the stuff doesn't expire) for special occasions or when I am pregnant and shouldn't be drinking as much caffeine.
Here are some other coffee substitutes that might fix your caffeine coffee cravings:

Undoubtedly there are more coffee substitutes out there, but these are just ones I have heard of and might be of interest to anyone trying to knock down or completely get rid of their caffeine intake. Out of all of these listed I have only tried Postum and Pero. I am not going to boast that these will all taste exactly like coffee or will satisfy your cravings for caffeine, but they are definitely worth a try considering the negative health problems that too much caffeine can cause. At any rate, I would highly recommend an alternative like one of these if you are pregnant, breastfeeding, or have a heart issue. Moderation in all things.
