I just got the Starbucks (Saeco) Barista Digital Italia and the instructions state to program the machine to dispense 1oz of espressor between 25-30seconds. On coffeegeek it describes espresso as 1.5oz brewed between 25-30 seconds. Well which one is it? Because it seems that the same grind would obviously take longer if you wanted 1.5 oz of fluid vs 1.0. I am trying to adjust the machines grinder but do not know which standard to use. All inputs appreciated.
