I always thought I was grinding finer than most with the beans and 53mm machine. But anyways. On the synchronika. 20g rushed out I had to go finer and finer. I have my saint Anthony industries levy setting so I think is tamping a good amount. I now have it getting about 34oz in 30 seconds. But the pull doesnt look so sharp. The stream kind of flickers or pulses. Also the puck when I take out the filter. It's pretty wet. Water is sitting on the top. Of course when I take it out the water absorbs. But I dont think I can go any more course. Is it normal for e61 to have to be alot finer?
How to correct pulsing? I'm not getting much spraying on my bottomless portafilter. Just the pulse look
Grinder is e37j.
I have the same machine and similar grinder(E37s). I am also using Malabar Gold (MG) this week. I will do my best to try to tell you about my experience, and hopefully it can help you.
When I first used MG, I cranked the grind very fine and I ended up choking my Synchronika. Since you already know the setting for too coarse, I think you should perhaps experiment with MG until you get a really slow/long extraction, and then start dialing in from there. My pucks are slightly wet at the top right after an extraction, but are not wet in the middle. They are certainly not soupy wet. My grind is pretty fine; the Ceado produces a very fluffy grind which is a big mound in my pf, but it tamps easily. Here what it typically looks like:
I am using a VST 18g ridge-less basket and the extraction parameters listed at Josuma for MG. https://www.josuma.com/extraction-parameters/
. 203-204 degrees Fahrenheit (PID setting) is yielding the best flavor. I tried 207 just to taste, and it was bitter. I am guessing that under 200 would be a bit sour.
I am not tamping hard. Maybe 20 pounds? If my grind is too fine, I will get a slow extraction. I have played around with a bottomless pf and I see very thick and even extractions. Lots of crema. With the ECM double spout pf, my drop time is 5-6 seconds, and total extraction time to 30g is 30 seconds.
Bottom line -- go finer on your grind and see how it tastes. I get a very rich double that is nearly perfectly balanced. Neither sour nor bitter.
