When it comes to grinding coffee, there is a difficult balance between cost and quality. But maybe you don’t want to spend an arm and a leg to get into the specialty coffee movement. Maybe you’re fine with using a little elbow grease to get a decent cup of coffee.

With the Mini-Slim Pro, Hario has done it again, offering a budget-friendly hand grinder that will help you on your way to great tasting coffee. While the Pro has maintained the same shape, size, and ceramic burrs of the Mini-Slim Plus, there are a number of differences; the most obvious being the upgraded, cast aluminum handle and the body’s material switch from plastic to black-painted, stainless steel. These changes have resulted in a sturdier, more attractive hand grinder.

The grounds bottle, which can hold about 25-30 grams of coffee, attaches to the hopper via a bayonet mount, allowing an easier way to remove and pour your coffee into your brewer. The clear plastic lid with a silicone grip gives you a clear view of how much longer you have to grind without having to worry about the lid falling off. And with ability to grind for both pour over and immersion brewers, the stepped grind size adjustment mechanism is easy to use and easy to duplicate.

If you are coming from a blade grinder or pre-ground coffee, the Hario Mini-Slim Pro will open up a world of flavors and aromas in your morning cup of coffee.

Perfect travel grinder

I do recommend this grinder. Very good build quality. Handle and burr axle feels solid and well supported. Like a peugeot pepper mill. Not the most uniform grind but perfect for an aeropress or a V60. I have not done anything finer because a v60 ground is as much work as I want to do in the morning. Only nitpick is that grounds bin can be a little tricky to attach especially bleary eyed in the morning.

Mini-Slim Pro by Hario

This grinder is smoother than my last Hario. The handle is strong. However, the bass of the grinder tends to strip over the notch it’s meant to be held in. The two areas are weak, but the grind portion is solid.
