In my quest to get on well with Miss Silvia, I would like to determine what is the "good" espresso water temperature.
Using a dial type drink thermometer (the type used for milk frothing measurements), I measured the water coming out from Slivie after she has been on for about an hour or more, both from the Portafilter and from the frothing wand - but not in steam mode. In both cases I extracted a full cup volume, to minimise temperature losses due to warming the cup itself. I also held the tip of the thermometer away from the wall of the cup, to get a true measurement of the central part of the hot water.
In both cases my thermometer showed about 72 deg C, which I thought was too low, hence this post.
So;
Question 1: What temperature do others get? Please specify machine and temperature, when expressing water without coffee, and then with coffee (short black, of course).
Question 2: What is the "recommended" ideal temperature? I thought that the water hitting the coffee grind is meant to be 92 deg C, which should be therefore what comes out when there is no coffee loaded or from the wand. Even allowing for some cooling, I would have thought that 72 was too low.
Question 3: Can the solenoid pressure be adjusted on Miss Silvia? I am suspicious, that mine has too high a pressure, resulting in the water passing through the coffee grinds too quickly ( and not hot enough), and giving poor quality of extraction.
Thanks for your input...
