I did a small experiment today
I did a small experiment today; tried some coffee beans from Bali that my mother-in-law bought. It’s been lying in my fridge for a bit too long perhaps. As you can see the beans are quite large.
I tried it on the 3rd step setting on my Hario grinder and I immediately saw that it was much too coarse – probably the beans were too dry.
As expected, the coffee went through the machine in probably less than 10 seconds. The resulting coffee was almost transparent, no crema at all, and very bitter.
Update: I tried again the day after, with the grinder on setting 1, and this time I got perfect crema and the coffee tasted better!
