A Comparison of Premium Hand Grinders for Coffee and Espresso
The ascension of the grinder to its status as the most crucial piece of brewing gear is well deserved. More than anything else the grinder has the potential to make, or severely limit the flavor quality of brewed coffee. It’s natural then for this movement to extend across new territory -- the world of mobile brewing. The hand grinder, once considered a compromise for convenience sake, has been reinvented to contend with some of the best electric home grinders on the market. Whether you’re sitting around a campfire, summiting a mountain, riding economy class, recharging in the office break room, or trying to keep it quiet in the kitchen at 6:00 AM, hand grinders have made it possible to brew excellent coffee, anywhere.
Over the last few years, several premium hand grinders have been introduced to the market. These grinders share a few defining characteristics, including precision-cut steel burrs, a secure center shaft riding on bearings, and an overall build quality that promises durability and a long lifetime. These features are considered standard for a quality hand grinder and, in essence, are all that’s needed for a uniform grind. That being said, the rather straight-forward requirements can make it somewhat difficult to determine which grinders stand in front of the rest. But there’s good news -- we’ve done the work for you. We've sourced five of the most popular premium hand grinders on the market and put them to the test, highlighting the strengths and weaknesses of each. Features are what truly distinguish these grinders from one another and this blog is intended to help you find the grinder with features most relevant to your needs.
Orphan Espresso Lido 3 - $195.00
Prices here reflect current listings as of May, 2018.
Possibly the most well-known of all premium hand grinders, the Lido was one of the first to gain the attention of the specialty coffee community. Over time, Orphan Espresso developed a few iterations, evolving the Lido 1 from a very basic looking tool into the highly refined Lido 3.
Fit and Finish
The Lido 3 is comprised of aluminum, stainless steel, silicone, and BPA-free plastics. Unlike previous versions of the Lido, the Lido 3 is made to be very lightweight relative to its size. The slim Aeropress-like hopper, made of a BPA-free medical grade plastic, is easy to hold for long periods of time and is semi transparent, allowing you to see the beans as they fall into the burrs. The grounds container, made of RTP PermaStat ABS plastic, is a highly durable static-resistant BPA-free plastic engineered to be tough, lightweight, and to keep grounds from sticking to the inside. The Lido 3 is the biggest of the hand grinders, at 13.5" in height, about 3" in diameter at the base, and 2" in diameter at the hopper. It weighs about 2.4 lbs, making it the heaviest hand grinder as well.
The Lido features a stepless grind adjustment with dual threaded rings. Loosen the top ring, then twist the bottom ring to select a grind size. Tighten the top ring back down to lock in your setting. Two blue lines serve as reference points for recalling settings. The top line, painted on the body of the grinder, remains stationary. The bottom blue line on the bottom grind adjustment ring indicates the distance from the stationary line.
The Lido E, which is an iteration geared towards espresso grinding, features a finer thread pitch in the adjustment ring. A lateral inch of movement of the Lido 3’s adjustment ring will produce a more substantial change in grind size than the same movement of the Lido E’s adjustment ring. This makes it easier to dial in the grinder for espresso, where tiny changes are sometimes necessary.
- 48mm hardened steel burrs mean quick grinding. Combined with a 70 g capacity hopper the Lido 3 is well fit for those who brew several cups at once.
- The Lido features a folding handle and includes a neoprene carrying case, making it easy to stow and bring along on trips.
- A full grind range, covering everything from Turkish to a 10 cup Chemex, means the Lido 3 can be used for any brew method.
- Although the reference lines are sufficient to recall grind settings with fair precision, the process of unlocking the top ring, adjusting the bottom ring, then tightening the top ring, is a bit difficult and more involved than other grinders.
- The Lido has a relatively short handle and tall body. Especially when grinding for espresso, the grinder can begin to wobble because the bottom half of the grinder is unstabilized by your hand. Sometimes it’s more comfortable to place the grinder between your knees while grinding.
Helor 101 - $259
It looks to be straight out of Cupertino, and sort of is. The Helor is a stunning hand grinder crafted from 6000 Series aluminium -- the same aluminum used for the iPhone 6. As elegant as it is precise, the Helor is comprised of the highest quality materials and offers uniformity of grind on par with the best hand grinders.
Fit and Finish
The Helor features a single-piece body cut out of a block of aluminum. The body, both roller bearing holders, and the outer burr holders are a seamless, solitary chunk of aluminum. Ceramic bearings are used instead of steel or brass bearings because they require no oil and can be washed with water. The wooden handle provides plenty of surface to hold while grinding, and the arm of the handle seems to be the perfect length to provide leverage for even the finest settings. The body and grounds chamber hold about 30-40 g of coffee. The diameter is approximately 2.1", height is 6.6", and weight is 1.28 lbs. Disassembly is extremely straight forward, thanks to the Helor's clean and minimalist design.
The Helor’s three point grind adjustment knob, located on the underside of the body, is familiar to those who’ve used the Porlex or Hario Mini Mill. 11 circles and one solid dot are etched onto the underside of the center burr. A small hole in one of the adjustment knob’s arms serves as a reference to the solid dot on the burr.
- Perhaps the most unique feature of the Helor is its inclusion of dual 38 mm burr sets. The first set, known as “Conventional burrs” are cut specifically for filter coffee grinding. These burrs, made from Martensitic Steel, shine at coarser grinds -- like what would be necessary for single-cup to full capacity Chemex brews or French Press. The second set included with the Helor are the “Contemporary Burrs”, which are the same burr set found in the Feld2. The contemporary burrs excel with finer grinds -- like espresso or V60 grinds -- and offer a more uniform grind at finer settings than the conventional burr set. The option of installing different burrs for different brewing applications gives the Helor an advantage over other grinders because its optimal range is more broad.
- Excellent materials and construction, promising an extremely long lifetime.
- Elegant, minimalist, and modern aesthetic.
- Compared to most other options, the Helor is very expensive. This is partly due to the dual burr sets.
- Although the grinder is highly durable, the aluminum body is very easily scratched. The outer body will display the grinder’s history of bumps and falls.
- Because it’s so smooth, the outer body can get a bit slippery during longer grinding sessions where sweat may develop on your palms.
Knock Aergrind - $159.99
The Aergrind may just be the ultimate grinder for the frugal traveler. Designed to fit inside an Aeropress plunger, the Aergrind is the smallest grinder in our lineup and makes for the perfect addition to your hiking or camping gear, or even a home brewing setup. This economical grinder offers similar grind quality to other premium models for a fraction of the price.
Fit and Finish
The Aergrind features a 38mm ceramic-coated steel burr set, familiar to those who’ve used the Feldgrind or Feld2. The Aergrind stands only 14.5cm high and has a diameter of 4.7cm. A simple removable steel handle with a plastic knob fits over the center shaft against a thin black plastic lid. The Aergrind also features dual bearing mounts and an anodized unibody milled from aluminum. Like Knock’s other grinders, the diameter of the Aergrind feels perfect for the hand and grinding is smooth.
Like Knock’s other models, stepless adjustments to grind size are made at the top of the grinder. Hold the lid in place and rotate the handle to adjust grind size. A numerical reference from 1-12 is imprinted on the top of lid. Each number has two dots between them, for total of 36 reference points. A small notch near the base of the handle serves as an indicator for the current setting. Because the Aergrind requires no disassembly when adjusting grind size, changes can be made faster than you can say, “Made By Knock”.
- Fits inside the chamber of the Aeropress’s plunger.
- Similar grind quality to the Feld2 at a lower price.
- Super fast grind adjustment.
- The handle and rubber sleeve do not fit inside an Aeropress with the grinder.
- Center burr has a very small amount of lateral play.
- The grounds container can sometimes slide out of place while grinding because your hand must grip part of it.
Knock Feld2 - $239.99
Knock’s newest iteration of the popular Feldgrind is a refined tool that every coffee enthusiast needs to have. The Feld2 is one of the most comfortable and practically designed hand grinders we’ve ever used. Big enough to grind for a full Chemex at home, yet small enough to stow away in any bag. The Feld2 is one of the ultimate gadgets for home brewers and travelers alike.
Fit and Finish
Similar to the Aergrind, the Feld2 features 38mm ceramic coated steel burrs, dual bearings, a rubber sleeve, and a milled aluminum unibody with black anodization. The grinder stands 8.5” high, 1.97” in diameter, and a depth of 6.25” with the handle. The Feld2 incorporates a fixed steel handle with an aluminium knob which is permanently attached to the lid. The two slots in the underside of the lid must be aligned with two separate parts of the grinder’s center shaft in order to lock down. Once in place the handle is extremely stable. The grinder can hold over 30g of beans and has a very large grounds container. The stability of the handle combined with the Feld2’s perfect diameter and handle length make for buttery smooth grinding.
The Feld2 is adjustable via the lid. Hold the lid in one place and rotate the handle to adjust grind size. Like other Knock grinders the Feld2 is stepless and features 12 numerical reference points on the lid. An arrow at the base of the handle serves as a point of reference for the current grind setting. The grinder requires no disassembly to adjust grind size so any desired changes can be made on the fly.
- Very sturdy handle makes for smooth grinding.
- Quick grind adjustment without disassembly.
- In our opinion, the Feld2 has a perfect body diameter and knob at the end of the handle for a comfortable grip.
- The double locking lid can be difficult to put in place. Two slots must line up perfectly with two different parts of the center shaft. This takes some getting used to.
Comandante C40 MKIII - $250
The Comandante Mk.III hails from Germany, where some of the best equipment used in specialty coffee shops is made. So, understandably, the expectations for this grinder were high. Although it’s rumored some of the first production models had performance issues, the latest grinders are well built and offer excellent grind quality. The price of this grinder is higher than others that offer similar performance, but at the core the Comandante is a stylish, versatile grinder that is a pleasure to use.
Fit and Finish
The Comandante sports a stainless steel body wrapped in a thin wood veneer treated with a natural wax oil, high-nitrogen martensitic steel burrs (which are highly resistant to pitting), an oak wood handle sourced from the Black Forest, stainless steel bearings, crank and axle, a BPA-free internal plastic frame, a glass grounds container, and a plastic lid attached to the end of the handle. The Comandante has a diameter of about 2.4", a height of 6.3", and a weight of 1.63 lbs. Its hopper and grounds container can hold about 40-45 g of coffee.
The Comandante is one of the few premium hand grinders with stepped grind adjustment. A plastic knob on the underside of the unit controls grind size in ‘clicks’. Part of the benefit of stepped grinding is that it allows the user to replicate the exact same setting over and over. By zeroing out the burrs then counting clicks, specific settings can be referenced.
- Transparent lid and grounds container shows what’s left and what’s been ground.
- Full range of grind sizes.
- Unique wood veneer styling.
- Stepped adjustment is sufficient for small changes to espresso.
- Great grinder to use for Turkish coffee.
- Glass grounds container.
- Consists of many plastic parts.
- Performance is comparable to grinders that are quite a bit less $.
Kinu M47 - $329
The M47 in early 2019 is one of the most robust portable hand grinders available. Constructed primarily of steel parts, it is solid to hold (and noticeably heavy) with little slop or play in the parts. The grinding action is incredibly smooth and its 47 mm conical steel burrs make short work of your bean dose even at espresso-fine settings. Its weight and its open-top design make it less convenient for travel, but overall this is a superb hand grinder.
Fit and Finish
Kinu has clearly put a great deal of thought and care into the design of the M47, and while none of the other grinders in this comparison feel cheap, it does evoke a greater feeling of durability and stability than some. The M47 is primarily made of stainless steel - only the handle pommel and some other trim parts are made of black ABS plastic. Inside is a set of 47 mm “Black Fusion” coated conical steel burrs, four steel bearings, and internal steel supports. The hopper portion can hold 30-40 grams of whole beans on average, though we have been able to squeeze in 50 with certain denser coffees. On the novel side of things, the catch cup uses a set of magnets to attach directly to the ring burr, so it can be removed with a solid tug but stays fixed in place while grinding. The grinder measures 8.25” high, 2.75” deep, and 7.8” wide with the handle attached (the handle easily unscrews for storage, but no holster is provided with the grinder). At 2.3 lbs, it is a heavy grinder compared to others.
Grind adjustment is micro-stepped: each click on the adjustment wheel corresponds to 0.01 mm of burr travel, which is more than suitable for dialing in espresso. The adjustment wheel is clearly marked with numbers and dashes, each registering a click thanks to the detents, and there are 50 clicks per revolution. The top screw must be loosened slightly for easier grind adjustment, but otherwise it is simple and clear to make adjustments and record your desired settings to return to later.
- Exceptional build quality and smooth grind.
- Great grind performance for espresso and manual brewing.
- Generous manufacturer warranty (5 years).
- Fast, simple grind adjustment with actual reference for burr distance (0.01 mm per click)
- Weight and bulk are less travel friendly.
- Coarse grind settings yield more fines. Our 600 mL Kalita Wave brews tasted somewhat muddy.
- Some users found the brushed steel hard to grip, and the ABS thumb stopper (which prevents the grinder rotating in the hand) to be uncomfortable.
- Some users have reported that magnets in the catch cup may come loose or dislodge completely.
- Quite expensive compared to others with similar grind performance.
From size to style, price and application -- there are several things to consider when buying a hand grinder. Our approach here at Prima is to curate a condensed selection of equipment through first-hand experience and judgement of quality, value, and features, then present the best to you. Although each of these grinders produces largely similar uniformity of grind (so similar we didn’t feel it was worth comparing), there are plenty of distinguishing features. There’s a grinder for everyone, and we hope this comparison guide was useful in choosing a hand grinder most relevant to your brewing needs.
