Subject: Temperature of water
Hi,
I'm as new as you can get when it comes to espresso machine. I've
had a Breville 800ESXL Die Cast for 10 months and I've been
practising and practising, for the last two months,to get everything
right and have a long, long way to go yet. In the specifications for
Breville it says;" The Breville boasts a thermoblock heating system
that maintains an ideal 204 F. temperature during extraction." I
tested one day what the heat of the water was during extraction and
I've done that 5 times one after the other and each time the
temperature was 170 F. Could you tell me if the temperature of 170 F.
is about what it should be for extraction of the coffee. The way I've
done that is that I let the machine warm up for about one hour and
than I put a cappuccino cup under the filter holder with a digital
thermometer in the cup while the water was seeping in the cup, and
everytime the temperature was 170 F. Does that sound good to you? I
would appreciate your comments on that. Thanks Maggielari

Or "surf" off dual thermostat relays from steam/boiler. Cycle between
them or blow off some steam from the higher steam temps for feeding
into an extraction to get it up closer to specs. Exacting way to go at
it, ain't it. Carefully between half blasted and burnt bitter before
the boiler goes low to sour.

No, that's way too cold., you'll underextract & the resultant coffee
will be sour. Proper brewing/extraction temps are the SCAA brewing
standard 195F - 205F, depending on roast degree & beans/blend.

Or, polish it & sell it on eBay for more than a good Gaggia costs.

craig,

170F in the cup should be about right, considering temperature drop in
the portafilter and dropping into a cool/cold cup.

Right, but he said: "Could you tell me if the temperature of 170 F.
is about what it should be for extraction of the coffee. "...
Extraction being the operative word, not cup temp.

but 170F in the cup would derive from about the right temperature at
the point of extraction.

sooooo... it's sorta correct and sorta not. if one thinks there is
no temp loss at all between showerscreen and cup, then it would appear
170F is incorrect.
