Findings for those who can not watch the video:
1. Espresso with crema: Fuller mouthfeel/body, oily, heavier similar to French press.
2. Espresso without crema: lighter mouthfeel, but the flavors seemed brighter similar to a drip machine or pour over.
The Coffee Queen @ http://thecoffeeqweenblog.wordpress.com/ tried out the experiment. She found the espresso tasted more bitter without the crema. Different results! Though I don't know if I could doing this over again, too much espresso right now.
And yes, you see a USPS box on the kitchen table among other things. This is what happens when the Girlfriend is away. Things tend to leave their "proper places."
(I would like to give credit to www.jimseven.com for giving me the idea to do this, and some of the vocab to describe what I was tasting.)
