It's funny people associate crema with good tasting espresso given the crema is the worst tasting part of an espresso
This is completely false if the espresso is brewed with freshly ground and properly roasted beans with correct temperature and pressure. The texture of the crema also says a lot about the quality of the extraction.
Yup. I bet they haven't tried scooping the crema and tasting it by itself. Since doing that, I now scoop and throw away the crema every time.
