Is my Timemore wearing down?
I have a Chestnut C3 ESP pro since almost two years. Super happy with it btw. Use it daily 2x or 3x.
Since I started doing espressos (with my Cafelat), I have noticed that I have go to finer and finer on the setting. I know different coffee beans need different settings, and I know the Espresso recommended range starts at 0.8.0.
This was too coarse from the beginning, so I had to go down at 0.7.2, then 0.7.1, 0.7.0, 0.6.2... long story short, I am now in 0.5.2 and I have tested long enough that I can't blame it on coffee bean varieties. I read somewhere that <=0.6 should probably be avoided.
Are my gears wearing down? Is this cause for concern?
