    If I were weighing shots would include crema, pretty difficult not to.

    I have a Lungo in front of me now, extracted from 18 grams of Ethiopian Gambella roasted 5 days ago, thick layer of crema, viscous mouth feel and big cocoa flavours.
    Oh man ... just roasted 200g of Gambella, cooled and straight through my Hario sock. Fantastic! My new favourite Ethiopian! It's almost a dead ringer (visually) for the Ardi.

    Bit like some of the posts in this thread for a while there I thought Ray T Coffeepro had reappeared.

    Reckon its time for some more popcorn.

    The crema's pretty thick for a few minutes. I ran out of coffee - sorry! Tamp pressure was 4 and 6 for time.

    Of course the crema won't be as thick after 2 minutes, all crema dissipates with time. The thicker it is at the start, the longer it will last. Also cup size and type make a big difference to crema thickness and quality.

    Have you tried the suggestion above of letting your beans rest a little longer? It might yield a slightly finer, more stable crema.

    Can I also see your tamp and preinfusion settings?

    Cheers Matt
    Tamp lighter, interesting. So Grind finer, tamp lighter. You can't change the dosage though, so what do you mean by put in less or more?

    Also, I lowered the pre-infusion/pressure to 55 from 60

    Pretty simple setup, main thing is to ensure probe is located well into the bean mass.
