Hello everyone
regarding the old advice of ~50-60 ml of double espresso extracted in ~30 seconds for a great double-shot quality.
Two questions:
(1) When do you start the timer for 30 seconds - from the instant the first drip of coffee appears out of the filter basket/spout or from the instant when you flick the switch to start the water pour/extraction?
(2) Does the manual pre-infusion change anything?
I have Rancilio Silvia 2010 model and I tried manual pre-infusion a few times (flick the pour button for 2-3 sec, stop pour button for 2-3 sec, flick the pour button for 30 sec) and the result was no better than not doing pre-infusion manually at all, i.e. just flick the pour button for 30 seconds.
Perhaps I am doing manual pre-infusion wrong or perhaps on this kind of home machine it makes no difference (a waste of time and effort) or perhaps I am not timing it correctly.
Thanks for advice and opinions on (1) and (2) above.
