Hi guys,
Made my morning cuppa today and had some rather unusual results. The extraction was quite slow, probably didnt start dripping until about 20 seconds after pump on. However I dont remember the grind being finer than usual, or the tamp deeper than usual. What really surprised me was the globules of oil I saw in the cup once it had finished. See below. It looks as though the cups just been used to store the drains of a Sunday roast!
I had no idea what could have caused this so I sinked it and tried again after cleaning the grind chute, the tamper, mug, portafilter, basket, group etc to remove whatever may have been causing it. Second time around was much the same. The photos actually of the second cup which was not as bad as the first.
The beans I used were Espresso Perfetto from Alan Frew, and Ive used half this bag already with never having seen these results. I then cleaned again and made one with Espresso LAC Blend and that was fine, though still a little slower than it should be.
What would be causing this? I could imagine the slow extraction process may have brought more oils out or something but Ive had slow brews before and have never seen even a skerric of this. Ive also used this blend many times before, and the last cup I made with this blend was normal rich crema. The taste wasnt particularly pleasant, but I wouldnt say burnt.
