    HELP! Breville 920xl espresso problems, how to get ok results from old beans

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi Everyone,

    My work place recently purchased the "dynamic duo" breville smart grinder and 920xl machine for the office, so far since we have had it been getting mixed results intially quite good now a few weeks in not so good. I initially calibrated it to produce good results but as time goes on Most of the staff fed up with the poor and inconsistant coffee an reverted back to the old Aldi pod machine .


    I think i have a fair understanding of using this machine as i have the same one at home. I am really struggling to get decent espresso out of the machine at work. Getting a terribly bitter and burnt flavour. Current recipe producing a 1:2 ratio (20g coffee : 40g espresso) in about 28-30 seconds of extraction. I have tried altering the grind size to get less bitter flavour but this is increasing the extraction rate and having the same effect as over extracted.


    My initial thoughts are that the coffe being purchased (grinders band espresso roast benas from woolworths) is not up to standard. However being on the office account we are limited to purchasing beans from woolies. I know i wont be able to ever achieve great results from poor beans but how can i change the grind / extractoin ect to produce ok results for milk coffees from old beans.


    The machine is in danger of being raffled off if i cannot get it producing good cofee quick smart.

    Any help or guidence would be great.

    Thanks

    Ben

    Beans will be a huge impact for sure. Supermarket beans including Grinders (which is owned by Coca Cola Amatil) have a used by date of more than 6 months (sometimes a year!) - wayyy too long.
    Unfortunately you are limited here - is it worth bringing in some beans from a local cafe/roaster to prove a good shot can be achieved?

    Also when was the last time the machine was cleaned? Is it getting hot enough or is it too hot? A good clean might solve some of these issues (but not always).

    Your extraction seems okay from your notes, 20g in 40g out in 30 sec is usually a good starting point and should atleast produce a reasonable coffee.

    Just buy some fresh beans and demonstrate the nice coffee. Then go round with the collection box and tell them they'll have to pay a bit more if they want decent coffee. If that fails, offer to buy the machine yourself at a knockdown price, you know it's capable. And if you don't want it sell it on here. Win, win.
