Barley espresso - is it still espresso?
I have been following a thread discussing barley espresso. The thread has devolved into some mean spirited commentary but the original poster did expand my horizons. I never had a clue this even existed as a beverage let alone a coffee alternative. After a fair amount of bickering if it even deserved to be called espresso of any kind (which never was fully resolved) most agree this is not really espresso. A beverage, yes, but not true espresso.
