    Measured with digital scale: 10g of water from three short bursts of the pump./\/r


    That is interesting, as while it is enough water to dampen the grounds (they expand abit and create a better seal, especially around the edges), it is not nearly enough water to have the thermal inertia necessary to heat the grounds up and start the brewing process.  
    Thats why better machines have adjustable settings....

    Secondly in the case of the EM series... Single or double basket... Course or fine grind ... Soft or hard tamp... It will all impact on what you get VS expect from any pre wetting / infusion.

    Coffee is not painting by numbers...  That is why 2 + 2 = 5 where 5 =great coffee.


    Then there is the issue that the majority of people can not tel the dif any way...  Little bit like having $3K speaker leads in my car and being over 50...  My hearing is shot, too much interference... But guess what .... Mine is better than yours.

    Theory is one thing / Practice is another and then there is the issue of drawing long bows...
