I'm surprised this tastes good.  I was expecting a heavy, nasty flavor like cold lentil soup juice, malta, or malted (though some swear by these aquired tastes.)  To be Coffee and Tea Festival technical, barley iced tea is really an infusion because it lacks Camellia sinensis (tea) plant. 

However, that's not why we're here.  Mugicha actually tastes good.  This roasted grain provides a smooth, comforting nutty taste and is not bitter say like black pekoe tea where you find yourself trying to "doctor it up" or conceal its taste with lemon, sugar, and the like. 

I particularly enjoy the convenience of this mugicha format because it makes it easy to have iced tea in the summer without heating the whole kitchen.  The special tubular tea bag with pulverized grain is to be simply inserted in a plastic two liter bottle of water and place in the refridgerator until desired color/temperature.
