Hi,
Can someone please explain the method for me?

All explanations I've found are somewhat vague, and once and for all I'd like to know how to do that properly (a picture would be nice)...

Thanks a lot

I have no pics but I'll try to explain.

Take a styrofoam cup.  8oz is probably best but larger sizes will probably work just fine.

Cut off the bottom leaving a smooth edge all around the top part where you made the cut.  Take the bottom that you have cut off and poke a hole in the side of that near the bottom that is just big enough to stick the probe of a thermometer in.  Take your cut-down cup with the hole in it and the temperature probe stuck in the hole and hold it up over the group-head (without the portafilter in the machine of course) so that the rim seals off all around the group-head.  Then turn on the pump so that water starts flowing out of the group-head, into the bottom of the cup and onto the thermoprobe.  Then you take the temperature readings of that water.

And, if you happen to have a bottomless portafilter, you can put that styrofoam cup bottom right into it, put the probe through the cup just below the edge of the portafilter, and have just that much less opportunity to burn your fingers.

You can find a picture here:

Good timing, Randy!

I'm going to start measuring temps on the Sirena, and this is just what I needed!

Grazie mille,
Wayne

Would this still work if, instead of a probe from a cooking thermometer, you stuck the end of a steaming or candy thermometer in the cup?

Any kind of accurate thermometer should work but instant-read helps a lot.  When I've done this and not used an instant-read thermo then I'll touch the brew-head or something with the end of the thermo right before I check the temps so it doesn't spend a lot of time getting up to temperature...it's already close.

Well, that would give you the temperature in the cup, but that isn't what you need to know.  What you are looking for is the temperature at which the water goes into/through the puck.  Putting the end of the thermometer right up as close as you can get it to where the espresso exits the puck is as close as you are probably going to get to that.

By the time the coffee falls to the cup it can have lost quite a few degrees.  Check it in both places to verify.

in my sig...  the over-the lip method is easy and by far the most accurate.
