What is the best grinder that:
is considered all-purpose (grinds coarse enough for cold brew, French press, through to pour overs & Chemex, and fine and consistent enough for espresso using non-pressurized baskets), and;
has very low or even zero retention to allow single-dosing (eg. 18g beans go in, 18g grounds come out)?
I’ve sort of been in a long search for a grinder that fits that criteria. I recently purchased a Rancilio Rocky, and while it is an excellent grinder that grinds a consistent grind-size, this grinder’s design has a chute that gathers up to 2-3g of coffee when single dosing (18g of beans go in, 16g of grounds come out.)
My needs are to have a multipurpose grinder that allows a multitude of slower immersion and faster brew methods (including a fine espresso grind for non-pressurized baskets) & doesn’t retain too much per grind cycle, which easily adds another 5-8 mins in my brewing routine just trying to tap and brush the grounds out of the grinder.
Any help would be most appreciated 👍
