Hario Mill: A Complete Guide to Hario's Hand Grinder Lineup

Hario has been making coffee equipment in Japan since 1921, and their hand grinders were some of the first affordable ceramic burr options that specialty coffee drinkers could actually find in stores. The Hario Skerton, Skerton Pro, and Mini Mill (now the Mini Slim Plus) have introduced thousands of people to the world of hand grinding. They're affordable, widely available, and produce decent coffee for the price.

I've owned three different Hario mills over the past five years. They were my entry point into manual grinding, and I have a genuine fondness for the brand. But the hand grinder market has changed a lot since Hario dominated the budget segment. Here's where their current lineup stands and whether they still deserve a spot in your kitchen.

The Hario Skerton Pro

The Skerton Pro is Hario's most popular full-size hand grinder. It sells for about $40 to $50, making it one of the cheapest ceramic burr grinders on the market. The Skerton Pro improved on the original Skerton by adding a stabilization plate that reduces burr wobble during grinding.

Grind consistency at medium and coarse settings is acceptable for the price. French press and cold brew results are perfectly fine. The ceramic burrs run cool and quiet. Capacity is generous at about 100 grams, which is more than most hand grinders offer.

Where the Skerton Pro Falls Short

The stabilization plate helped, but it didn't fully solve the wobble issue. At finer settings, the inner burr still moves slightly, producing a wider particle distribution than competitors like the Timemore C2. Pour-over results are noticeably muddier than what I get from grinders that cost $20 more.

Grinding speed is also slow. Expect about 90 to 100 seconds for 20 grams at a medium setting. The ceramic burrs are small (about 28mm effective cutting diameter), and the ergonomics don't help. The glass catch jar at the bottom is pretty but doesn't give you a good grip while cranking.

The Hario Mini Slim Plus

The Mini Slim Plus (successor to the original Mini Mill) is Hario's compact option. It's about 20cm tall, holds roughly 24 grams, and costs around $30 to $40. For absolute beginners who want to try hand grinding without spending much, it's a functional starting point.

The Mini Slim Plus uses the same ceramic burrs as the Skerton Pro. Grind quality is similar, though the smaller body makes it harder to hold steady during grinding. I've used one for camping trips where I didn't want to risk damaging a more expensive grinder.

Adjustment System

Both the Skerton Pro and Mini Slim Plus use a nut-and-spring adjustment system. There are no clicks, so settings are stepless but hard to reproduce consistently. I've resorted to counting turns from the fully closed position and even marking the nut with a permanent marker for reference.

This is one area where Hario is clearly behind the competition. Timemore, 1Zpresso, and even the Porlex grinders all offer click-based adjustment that's easier to use and more repeatable. The lack of clicks makes it frustrating to switch between brew methods, because finding your exact setting again requires trial and error.

Hario Switch vs. Competitors

Let me be direct about how the Hario mills compare to what else is available at similar prices.

Hario Skerton Pro ($45) vs. Timemore C2 ($65): The C2 is better in every grinding metric. Faster, more consistent, better adjustment system. The $20 difference is money well spent. The Skerton Pro's only advantage is the larger capacity (100g vs. 25g), which matters if you brew large batches of French press or cold brew.

Hario Mini Slim Plus ($35) vs. JavaPresse ($30): These are roughly equivalent. Neither is great, but both get you into burr grinding for minimal money. The Hario has slightly better build quality. The JavaPresse has a more comfortable grip.

Hario Skerton Pro ($45) vs. Porlex Mini ($65): The Porlex has a better build (all stainless steel vs. Plastic and glass), click adjustments, and fits inside an AeroPress. The Hario has larger capacity and a lower price. For daily home use, I'd pick the Porlex. For occasional use or large-batch grinding, the Hario makes sense.

Who Should Buy a Hario Mill

Hario mills make sense in a few specific situations.

True beginners on a tight budget: If you're spending $30 to $40 on a grinder to find out whether you even like hand grinding, the Hario is low risk. If you hate it, you're not out much money. If you like it, you can upgrade with better information about what matters to you.

Large-batch grinders: The Skerton Pro's 100-gram capacity is genuinely useful if you make French press or cold brew for multiple people. Most hand grinders max out at 25 to 30 grams, requiring multiple fills.

Gift buyers: Hario mills are widely available on Amazon, they come in attractive packaging, and they have strong brand recognition. For someone who's shown interest in coffee, a Hario grinder paired with a bag of good beans makes a solid gift.

Who Should Skip Hario Mills

If you already know you're serious about coffee quality, skip the Hario and start with a Timemore C2 or 1Zpresso Q2. The $20 to $30 difference buys you meaningfully better grind quality, faster grinding, and a proper adjustment system. Buying a Hario first and then upgrading within a few months is a common pattern I've seen in coffee communities, and it would have been cheaper to just start with the better grinder.

Maintenance and Longevity

Hario mills are simple to maintain. Disassemble the burr mechanism (usually two parts: the outer ring and inner burr), brush out grounds, and reassemble. Do this every two weeks for the best flavor.

The ceramic burrs last a long time, often 5+ years of daily use. Hario sells replacement burr sets for about $10 to $15, which is one of the cheapest replacement options in the market. The glass jar on the Skerton Pro is the most fragile component. I've seen people crack theirs by setting the grinder down too hard on a granite countertop. A silicone sleeve or mat underneath helps prevent this.

FAQ

Which Hario mill is the best?

The Skerton Pro is the best in Hario's current lineup for home use. It has the largest capacity, the improved stabilization plate, and reasonable grind consistency for the price. The Mini Slim Plus is fine for travel but compromises on ergonomics and capacity.

Can a Hario grinder make espresso?

Not well. The ceramic burrs don't produce fine enough or consistent enough particles for proper espresso extraction. You can get a fine grind, but the distribution will be too wide for even extraction in an espresso machine. For moka pot coffee, it works in a pinch.

Are Hario grinders still good in 2026?

They're still functional and affordable, but they've been surpassed by competitors in the same price range. The Timemore C2, 1Zpresso Q2, and even the Porlex Mini offer better performance for similar or slightly higher prices. Hario mills are no longer the default recommendation they once were.

How do I fix burr wobble on a Hario Skerton?

The Skerton Pro has a built-in stabilization plate that reduces wobble. For the older Skerton (non-Pro), aftermarket stabilization mods are available on Amazon and Etsy. These are metal or 3D-printed shims that sit between the outer burr and the housing to reduce lateral movement. They genuinely help and cost about $10 to $15.

Where Things Stand

Hario mills played an important role in making hand grinding accessible to everyday coffee drinkers. They're still serviceable grinders at fair prices. But the competition has moved forward while Hario's design has stayed relatively static. If you're buying new, spend the extra $20 on a Timemore C2 and get a noticeably better grinding experience. If you already own a Hario and enjoy it, keep using it until the burrs wear out, then upgrade.
