    2 degrees makes all the difference

    Iíve been using a Sunbeam EM6910 for a few months now. Iím actually onto my second machine after giving the first one I repaired to my brother. Iíve been slowly exploring its capabilities, but hadnít adjusted the brew thermoblock temperature as yet. Most of the posts Iíd seen on forums regarding this said the factory set 92degC was very accurate and right temp to sort of cover all bases. And Iíd had some excellent coffees, including espressos so was happy to leave it that way.

    However that changed today. I had an espresso yesterday afternoon of a Peruvian coffee that I got from my local roaster (green). It was fine, but definitely a bit dull, lifeless and ever so slightly sour. So I popped by his shop today and got him to make me an espresso as I know heís using the same coffee at the moment and itís roasted in a similar way. It was way better than mine with all the sweetness that I expected. One thing I noticed was that it seemed to be a little hotter than the shot I made yesterday and I thought there might be something in that. So when I got home I adjusted the brew temp on my 6910 to 94degC, aaaaaaand...... voila!! What a difference!! So Iíd obviously been underextracting many of my lighter roasts. The temp is really easy to adjust when you turn the machine on so Iíll definitely be picking a temp to suit the coffee from here on.

    Iíve read so much about how espresso is temperature sensitive, itís cool to be able to taste the difference for myself and have a machine that I can make adjustments on.

    The good one this arvo-

    Ah that's awesome to hear, and yeah it makes sense actually, even though the temp is only 2 degrees difference, espresso brewing is such an intense, volatile, high pressure process, that even that slight adjustment in temp would make a big difference... cool beans!

    I have been experimenting with temperature changes for different roasts and origins with pleasing results.
    I discovered this article recently which is well worth a read:--
