Help a newb out - uneven extraction?

For generic information on making espresso alt.coffee, coffee geek, Sweet Maria's web site and many others excel at this tutorial level of information. However, if you've been there and done that but have specific questions and concerns about getting the best espresso on the S1/VII/Mini-VII/Dream/Dream T, post those topics here.

Help a newb out - uneven extraction?

Post by jtbrasel » Tue Sep 17, 2019 7:26 am

I’ve noticed that my shots are extracting from only about 2/3 of the portafilter screen, so that no espresso is coming out of the front of the screen. This happens consistently. I’ve experimented with my tamping pressure - ranging from a very light tamp to very hard tamp and it makes no difference. What am I doing wrong? What else should I experiment with?

The following experiments night be worthwhile. Do these one at a time and observe the results. Also be sure your machine is level first.

1) Leaving the orientation of the screen pair alone, rotate the diffuser block 180degrees
2) Rotate both screens together by 90 degrees
3) Rotate each screen in relation to the other by 90 degrees.

Thanks! I’ll try those out.
