HI y’all. I am getting increasingly frustrated with my espresso journey, now peaking with a serious attempt on getting an acceptable shot.

My SO gifted me DAK beans, so i am trying to make the best out of it. I didn’t want to tell her the roast date has been a little longer than i normally aim for, but 6 weeks beans we still do okay right.

The shots run extremely fast 10 sec prefinsue, and another 10-14 seconds and its done to 1:2 or 1:2.5 ratio. The pressure only builds up to 5 bar. My first shot at 18.1 gr in and the initial grind setting was smooth to some extent, watery, and sweetness didn’t stick for long. Bitter at the end lingered. Hence i figured for the second attempt to extract more ‘mid’-shot by grinder finer and cut output shorter to prevent bitterness.

To my surprise, the second shot ran faster. Immediately hit with acidity, followed by harshness. Is this an underextraction? I couldn’t recognise defects from the bottomless pf as it run so fast. Didn’t see channelling perse.   All the variables I changed for the second shot should have promoted an increase in extraction but it didn’t. I don’t think going coarser is the route, as the pressure build up is at 5 bar low already.

My setup:

  • Lelit Mara X, descaler, relativly good quality dutch tap water, temp mode I 92C-94Cish. OPV set for 8 bar boiler pressure.
  • Pullman Filtration876 precision basket 17-19 gr
  • wdt
  • level tamping, either with normal tamper or normcor
  • DF64 gen 1, SSP HU burs, aligned myself with a couple of shims.

Since I got the Pullman basket, extraction time has drastically decreased, which I understand is expected with precision baskets. Results have been… varying. Also with a simple medium roast blend coffee, i moreover don’t even dare to serve it to my family, who just expect a classic. Shots turn out overly harsh.

I am 5 years into my espresso journey, thought i learned a lot. But realise tasting coffee becomes increasingly difficult and frustrating. I start doubting myself, do I taste floral or sourness, is this over or under extracted? One thing is certain, I have flashy gear, expensive beans, but distasteful coffee.

Hope to tap in the knowledge of some of the espresso gods in this lemmy.
