Pulling a creamy double shot of espresso from a Krups 4030 espresso machine. What a nice cup of espresso it makes when done properly.
A great shot of espresso is creamy, semi-sweet and has a smooth caffeine kick to it. A BAD shot of espresso will have nearly no foam and black or too much foam and almost white. Either will have too much acid in it, usually causing an upset stomach and the jitters.
I drink espresso because it makes me less bitchy than coffee does. lol
