While there are several alternatives available, one of the best choices is Pero all natural caffeine free instant beverage. Some coffee substitutes are made from a combination of herbal ingredients that still need to be brewed or steeped like coffee. Pero is an instant product just like Postum. However, unlike Postum, Pero is made from a simple recipe of all natural malted barley, barley, and chicory. The main flavor difference between the Pero and Postum brands lies in the wheat molasses. This ingredient gave Postum a slightly sweeter taste than Pero. This can be easily addressed by adding a little sweetener of your own. Although Pero does not contain wheat products, it can not be considered gluten free since the barley in the ingredients is a source of gluten. Other similar instant products include the brands Cafix and Caf-Lib, but grain for grain, Pero is one of the best coffee substitutes available.
