it is coffee but instead of just hot water falling over the coffee grains; they get perfectly ground beans(using a very expensive type of grinder so that all the grains r of uniform size) and then they place a small amount into a cup and apply 40 - 50 pounds of pressure to turn it into a coffee-puck, and then have a special machine force steam at 9 atmospheres through it to make i tiny cup of incredibly rich coffee(called capachino and i apologize for my incorrect spelling of it).
