I'm an espresso nut. I own a Giotto prosumer machine and a Macap grinder. My espresso of choice is Intelligentsia Black Cat, though I also like Gimmee's Leftist Blend. I've been trying for about 8 months to pour a rosetta but that has so far eluded me I just can't get the milk perfect yet...it's really tough. For those who are not aware of this, check out this video, which is a barista pouring plain old steamed milk into a cup of espresso. Nothing else, it's all in the texture:
