Yeah, I'm quite new to these. Btw, what kind of grinder is suitable for expensive beans?
Any recommendation? I'm planning to get a new one because mine is not washable and it's typical "blade grinder".
a "burr grinder" is the best way forward.. of course, by now, you've noticed that there're manual burr and electric burr grinders.
do take note to "pair" your espresso machine with your grinder wisely.
an expensive/good grinder, pairing it with a toy/entry-level espresso machine will not bring much benefit to the end result.
for example, your espresso machine is considered "toy level".. lots of plastic components, thin stainless steel at best.. pressurized for consistencies(albeit lacking quality extraction). so, if you pair it with an expensive grinder or commercial grade grinder, you won't get much benefit from it.. but those grinders will be a good keep should you one day upgrade your espresso machine later.
so when people recommend you a grinder of choice, do take into consideration of this pairing-combo..
some people recommend you something with a hidden agenda, meaning, they have something to fence it off to you.. selling you shit that they don't want to keep anymore.. beware of such salesman tactics.
