Helios Grinder: What to Know About This Hand Grinder

The Orphan Espresso Helios is one of those hand grinders that doesn't get talked about as much as the Commandante or 1Zpresso, but the people who own one tend to be fiercely loyal to it. I borrowed one from a friend for a month-long test, and I can see why. It's a surprisingly capable grinder with 47mm Italmill burrs that puts out a grind quality rivaling some electric grinders costing three times as much.

In this piece, I'll cover the build quality, grind performance for both espresso and filter, how it compares to the better-known hand grinders on the market, and who should actually consider buying one. If you're shopping for a premium hand grinder, the Helios deserves to be on your radar.

Build and Design

The Helios has a straightforward design philosophy: function over flash. The body is an aluminum tube with a matte anodized finish. It feels sturdy without being heavy, coming in at about 500 grams (just over a pound). The handle is a fold-out design with a wooden knob that's comfortable during longer grinding sessions.

What sets the Helios apart from cheaper hand grinders is the bearing system. It uses dual bearings on the shaft to keep the burrs aligned under load. Cheap hand grinders wobble during use, which creates inconsistent particle sizes. The Helios stays rock-solid.

The Italmill Burrs

The star of the show is the 47mm Italmill flat burr set. Italmill is an Italian manufacturer that supplies burrs to several commercial grinder brands. These are not the generic conical burrs you find in most hand grinders. Flat burrs produce a more uniform particle distribution, which translates to cleaner, more defined flavors in the cup.

At 47mm, these are also larger than the typical 38mm to 40mm burrs in competitors like the Commandante or 1Zpresso JX. Bigger burrs mean faster grinding and less effort per rotation. I timed myself grinding 18 grams of medium-roasted coffee for espresso, and it took about 45 to 50 seconds. That's fast for a hand grinder.

Capacity and Portability

The bean chamber holds about 30 grams comfortably. The folding handle and compact tube shape make it easy to pack in a travel bag. If you're the type who brings a grinder camping or on business trips, the Helios is more portable than the bigger 1Zpresso K-Max or Kinu M47, though it's slightly larger than travel-focused grinders like the 1Zpresso Q2.

Grind Quality: Espresso

I tested the Helios with my Flair Neo manual lever espresso maker and was genuinely impressed. The stepless adjustment lets you fine-tune the grind with precision that rivals the Kinu M47. I was able to pull 25 to 30 second shots consistently, with good body and a smooth finish.

The flat burrs give espresso shots a different character than what you get from conical burr grinders. There's more clarity and brightness, especially with lighter roasts. A natural Ethiopian processed through the Helios tasted noticeably more complex than the same bean ground on my friend's Commandante C40 (which uses conical burrs).

Dialing In

The adjustment mechanism uses a numbered dial on the bottom of the grinder. Each full rotation moves the burrs a set distance, and you can dial in to fractions of a rotation. For espresso, I found my sweet spot around 3 to 4 full turns from fully closed (zero point). Moving half a turn in either direction made a clear difference in shot time, so the precision is there.

One minor gripe: the numbered markings are small and can be hard to read in dim light. I ended up counting rotations by feel rather than reading the numbers.

Grind Quality: Filter Coffee

For pour-over and drip coffee, the Helios produces a clean, uniform grind that brews beautifully. V60 drawdowns were consistent, and the resulting cups had a transparency that showcased the coffee's origin character. I compared V60 brews from the Helios side-by-side with brews from a Fellow Ode Gen 2, and the difference was smaller than I expected. The Helios held its own against a $300 electric grinder.

French Press

At coarser settings (around 8 to 10 turns from zero), the Helios produces a good French press grind with fewer fines than most hand grinders I've tried. The cup was clean and full-bodied. This is one area where the flat burrs really show their advantage over conical designs, as conical burrs tend to throw more fines at coarser settings.

AeroPress

The AeroPress is the perfect companion for the Helios, especially when traveling. Medium-fine settings (5 to 6 turns) produce a rich, concentrated brew. Since the Helios is already travel-friendly, the pairing makes sense.

Helios vs. Commandante C40 ($250)

The Commandante is the most popular premium hand grinder, and for good reason. It has excellent build quality, a huge aftermarket for accessories, and consistent conical burr performance. The Helios matches it in build quality and beats it in grind uniformity (flat vs. Conical). The Commandante has a slight edge in grinding speed for coarser settings. If you prefer clarity and brightness in your cup, the Helios wins. If you prefer body and sweetness, the Commandante might suit your taste better.

Helios vs. 1Zpresso JX-Pro ($160)

The JX-Pro costs significantly less and delivers good espresso-capable performance with its 48mm conical burrs. The Helios produces a more uniform grind thanks to its flat burrs, but the JX-Pro is the better value if you're on a budget. For daily espresso use, I'd take the Helios. For a general-purpose grinder where cost matters, the JX-Pro is hard to beat.

Helios vs. Kinu M47 ($300)

The Kinu M47 is the Helios's closest competitor. Both are premium hand grinders with large burrs and precision adjustment systems. The Kinu uses 47mm conical burrs from Black Fusion steel, while the Helios has 47mm flat Italmill burrs. Grind quality is excellent from both, but the character differs. The Kinu produces a rounder, more traditional espresso profile. The Helios gives you brighter, more articulated flavors. Build quality is comparable. Pick based on your flavor preference.

Who Should Buy the Helios?

The Helios makes sense if you want flat burr grind quality in a hand grinder format. That's a niche audience, but it's a real one. Specifically, I'd recommend it if:

  • You drink light-roasted single-origin coffees and want to taste every note
  • You want one grinder that handles both espresso and filter with high quality
  • You don't mind hand grinding and actually enjoy the ritual
  • You travel and want to bring your grinder along

It's not the right pick if you grind for a household of three or more people (hand grinding 60+ grams gets tiring), if you want zero effort in the morning, or if you prefer the body-forward flavor profile of conical burrs.

FAQ

Where can I buy the Orphan Espresso Helios?

Orphan Espresso sells the Helios directly through their website. It also occasionally appears on Amazon through authorized sellers. Availability can be limited, so check back regularly if it's out of stock.

How long does it take to grind a dose with the Helios?

For a single espresso dose (18 grams), expect about 45 to 50 seconds of grinding. For a pour-over dose (25 grams at a medium setting), it takes about 30 to 35 seconds. The 47mm flat burrs are efficient and make the process quicker than smaller-burr hand grinders.

Can I adjust the Helios for both espresso and French press?

Yes. The stepless adjustment covers a wide range from very fine (espresso, Turkish) to very coarse (French press, cold brew). Switching between espresso and filter takes about 5 to 10 turns of the adjustment dial.

How do I clean the Helios?

Disassembly is simple. The burr set comes out for cleaning by unscrewing the adjustment dial and removing the inner burr. Brush the burrs with a stiff bristle brush every week or two, and you're good. No special tools needed.

The Takeaway

The Orphan Espresso Helios is a flat burr hand grinder that competes with electric grinders in grind quality while fitting in your travel bag. It's not the cheapest option, and hand grinding isn't for everyone. But if you value cup clarity and want a grinder that does both espresso and filter at a high level, the Helios is one of the best hand grinders you can buy. Try it with a light-roasted Ethiopian or Kenyan coffee and you'll immediately taste what those Italmill burrs can do.
