I have a very basic setup -
Graef Conical Burr Grinder - 25 settings - https://www.amazon.es/Graef-CM702EU-Molinillo-color-negro/dp/B00EO26GGC/
Cecotec Power Espresso - 20 bar - https://www.amazon.es/Cecotec-Power-Espresso-20-Inoxidable/dp/B0763N7WMP/
After trying to dial in my bean, I came to a seemingly unsolvable issue — Between two settings on my burr grinder, either my espresso extraction is too fast (leading to a sour taste), or not at all. I have kept dose, tamp, and brew temp (as much as possible) as constant as I could, but my first thought is that I would have to upgrade to a more expensive grinder, containing micro-settings that I could more effectively dial in the beans.
At the same time, the espresso machine is 50 euro and could easily not apply correct pressure/temp to the bean, causing the taste to be off, or not being able to push through the portafilter.
Has anyone experienced this kind of issue or have any advice on troubleshooting?
