    Espresso Consistency

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Ok, so Im sticking to milk based drinks until my Rocky appears but Ive noticed something interesting with the shots Im using for them. They look oily. Is this just due to the type of roast Im using or am I dosing/tamping incorrectly?

    Thanks!

    Do you mean like an oil slick on the top of the shot?

    Cant say Ive noticed it on top, just when the pour is starting. The liquid is very thick and has an oily sheen.

    Nah, nothing wrong. Its supposed to be thick, and somewhat oily, as the oils from the coffee beans contribute to the crema.

    Excessive oiliness may be a problem with the freshness of the beans, or as a result of much darker roasting (french, italian, etc.)

    Hi Grant,

    I have found that an spots of oil appear on the surface of an espresso if it has been heavily overextracted. Generally it is most apparent when the shot has taken 40 secs or more to complete extraction.

    Perhaps this is the case with you?

    This may be the case, although the oilyness is only really apparent at the start of the draw (extraction?). Ill pull some more shots tonight and see if I can describe it a little better.
