Has anybody tried Ecco or Caro? They are beverages made by adding powder to water or milk - and they contain barley, chicory and some other things.

Haha.. I guess not.

I've never tried it, but I looked Ecco up and found it mentioned in this blog. According to that, it's a decent substitute for coffee or tea because it has no caffeine. I couldn't really see much about the actual flavor though.
