(For those who saw my previous post, I misjudged sour as bitter)

I’m still dialing in the coffee beans I have and the shots are sour and watery and I’ve noticed that there is channeling

I’ve already tried grinding finer but that just slows down the shot, makes it even more sour and eventually nearly choking the shot

My puck prep is

  1. Weigh 18g
  2. RDT (which I sometimes exclude)
  3. Grind
  4. Add more ground beans or remove sons ground coffee to make sure I have 18g out of the grinder
  5. WDT Using the technique from Lance Hedrick’s video
  6. Tamp (the same way James Hoffman does in his espresso puck prep video
  7. Manually pulling 1:2.5 shot out of Breville Barista Express via program mode with the use of a scale to weigh the shot

Edit:

I increased the temperature to 95°C from the defualt 93°C and also learned that program mode is different from manual mode on a Breville Barista Express (its on pg 14 in the manual)

And the espresso shot is better now but there’s still sone slight channeling that I need to work on

    How recently was your coffee roasted? Espresso especially needs time to release CO2, and freshly roasted beans can cause inconsistencies and channeling.

    In general rest time corresponds with roast level:

    • Dark roasts - 1 to 1.5 week
    • Medium roasts - 1.5 to 2 weeks
    • Light roasts - 2 weeks +

      I did buy it from a local roaster, I’d say its been more than two weeks at this point

      They are medium roast
