    Question Extraction issue

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Does anyone know why my single group filter needs no firm tamping and with the same grind my double filter needs huge amount of tamping pressure. The resulting shot from single water struggles to get though and the double basket goes through too fast!
    I am using a Torino PU8000 with a sunbeam cafe series grinder. I still get 30ml in 28sec on both filters. This is the first machine I have purchased that gives a different extraction result, altering the grind will fix one but not the other and vice versa.

    There is a big discussion about this previously. I think the consensus was that its the single basket shape that makes the difference. And, a change of your baskets would allow you to use same grind and tamp across both baskets.
    Cant remember what brand was suggested. Sorry

    Hey BaristaMarty
    any idea what weight the dose is you using in each basket?
    i might be reading your post wrong but are you aim for 30ml in same time from both single and double baskets even though your using a larger dose in the double?
