The Basic is the unique mannequin and the costliest of the three. The Simplicity was the second launch. It swaps some metallic for plastic for a cheaper and reduced-weight espresso grinder. After a hearth destroyed the Kinu manufacturing unit in 2018, they rebounded by releasing a brand new espresso grinder, the Phoenix – a grinder rising from the ashes, if you’ll (1).

The scarce sources left had been used to create a simpler-to-produce grinder that satisfies the excessive customary of Kinu grinders and extra cheap pricing demanded by our clients.

With that transient abstract in thoughts, let’s get into the main points. 

Grind Consistency – 4/5

Kinu M47 presents wonderful grind consistency, which is true of each mannequin. All three function equivalent inside mechanics and the identical 47-mm conical burr set. 

The burrs are designed to ship very uniform grinding outcomes on the finer finish of the grind spectrum. This espresso grinder is finest fitted to Turkish espresso, espresso, Moka pot, and finer filter brewing strategies – like small pour overs or the AeroPress.

Pour Over Grinding

The M47 grinder handles coarser grinding, however that’s not its specialty. I wouldn’t essentially advocate Kinu M47 for Chemex or comparable preparation strategies.

There are some guide espresso bean grinders which might be higher choices for critical pour over followers. Evaluating Kinu M47 vs Comandante C40 pour over grinding functionality, the latter delivers extra constant grinds at coarser settings. Likewise, when evaluating Kinu M47 vs Baratza Forte BG, the Forte BG performs higher as a result of it was designed for “Brew Grinding” – although it’s an electrical grinder that can value you a reasonably penny.

Simple Grinding Adjustment

Kinu M47 has a stepless high-precision grind adjustment system, which is vital for an excellent espresso grinder. Dialing in an espresso shot requires much more exact grinds than brewing a pour over (2). Discovering the right shot on your espresso beans falls between two settings is endlessly disappointing. Nevertheless, stepless grind changes readily available grinders are sometimes clunky, making it troublesome to make massive changes or return to earlier grind settings. 

The M47 presents a best-of-both-worlds answer for simple dealing with. It has an apparent zero level, so that you’ll by no means lose your body of reference. Every rotation of the adjustment knob is marked with 50 settings, making macro changes simple, and each mark corresponds to exactly 0.01 mm of vertical burr motion. It’s a sublime design that’s much more user-friendly than the generally seen system of counting clicks.

Easy methods to Modify Kinu M47 Phoenix Grind

Adjusting the grind setting is similar on each mannequin and takes little effort. Loosen the nut on the prime that holds the deal with in place, flip the dial to alter the setting (clockwise for a finer grind and counter-clockwise for a coarser grind), then tighten the nut once more. Simple!

Construct High quality – 4.5/5

Construct high quality is the defining function of the Kinu M47s. They’ve a stainless-steel physique and crank arm; any plastic is sturdy food-safe ABS plastic. 

It’s not simply in regards to the premium supplies; the manufacturing high quality can be top-of-the-line.

The whole lot is machined to exacting requirements, making certain a easy, fluid, and quick grinding expertise.

The design of the inner parts promotes stability and auto-centers the axel whereas in use, and two units of metal ball bearings assist with grinding.

Variations Between Fashions

Construct high quality is one space the place the three fashions differ, although not in any approach that impacts grind high quality. 

  • The Kinu M47 Basic has a stainless-steel grinds catch cup that attaches to the physique of the espresso grinder seamlessly utilizing neodymium magnets.
  • The Kinu M47 Simplicity has a food-safe ABS plastic beans funnel and grounds catch cup.
  • The Kinu M47 Phoenix has an ABS plastic beans funnel and grounds catch cup, and the thumb stopper is changed by a silicone ring.

Burr High quality – 4/5

All three fashions have the identical 47-mm Black Fusion-treated hardened conical burrs. Black Fusion remedy is a proprietary burr coating that hardens the Kinu M47 burr set to extend its lifetime and guarantee long-lasting grind consistency.

Espresso grinder burrs are usually conical or flat. With out embarking on a geometry lesson, there are some things to learn about each (3).

Conical burrs, like these within the M47, produce extra fines, resulting in drinks with a heavier physique and fuller mouthfeel – nice for espresso.

Conical burrs have the benefits of much less warmth era and decrease grind retention. Flat burrs are identified for higher grind uniformity, which ends up in a clear cup widespread with pour over lovers. Finally, it comes down to non-public desire when deciding which burr form fits your espresso type.

Portability/Capability – 4/5

The Kinu M47 espresso grinder may be very transportable, even offered with its personal journey case. All three fashions have a 40 to 50-gram hopper capability, sufficient for about 4 pictures of espresso or cups of espresso. The Basic’s metallic grounds catch cup is barely smaller, holding as much as 35 grams versus 40 grams for the opposite two. The all-metal Basic is essentially the most rugged of the three grinders but in addition the bulkiest and heaviest.

Listed here are the detailed specs, with the crank arm in place:

  • Kinu M47 Basic: 8.25″ x 2.75″ x 7.8″ and a pair of.3 kilos
  • Kinu M47 Simplicity: 8.20″ x 2.75″ x 7.8″ and a pair of.1 kilos
  • Kinu M47 Phoenix: 8.20″ x 2.75″ x 7.8″ and 1.6 kilos

Worth – 3.5/5

The Kinu Basic is pricey for a guide espresso grinder, normally priced round $350. That is aggressive with comparable choices just like the Comandante C40 and Mazzer Omega. Nonetheless, it’s getting tougher to justify paying these costs with higher-quality finances choices getting into the market from manufacturers like Timemore and 1Zpresso.

The Kinu M47 Simplicity and Phoenix are rather more inexpensive. The Simplicity is about $100 lower than the Basic, and the Phoenix is round $50 lower than that. Until you’re deadset on a magnetic grounds catch cup, they provide much better worth for cash.

Issues We Preferred:

  • Excessive-quality Black Fusion-treated burrs
  • Simple-to-use stepless adjustment
  • Precision machining makes grinding simple
  • Sturdy espresso grinder with wonderful construct high quality

Issues We Didn’t Like:

  • Comparatively costly price ticket, particularly the Basic
  • Not as nicely fitted to pour over brewing

Don’t Purchase The Kinu M47 If…

  • You don’t make espresso: The burrs of the M47 are designed for espresso and advantageous drip grinding. In case you favor pour over or French press brews, select a espresso hand grinder made for these brewing strategies. The Mazzer Omega and the Comandante C40 are nice choices of comparable high quality.
  • You don’t wish to grind manually: Choose to let a motor do the work of grinding your beans? Try the Baratza Sette 270. It’s a terrific grinder in the identical value bracket and encompasses a set of 40-mm conical burrs.
  • You need one thing cheaper: Our favourite choice for budget-friendly espresso grinding is the 1Zpresso JX Professional. Evaluating the Kinu M47 vs 1Zpresso, the latter has bigger burrs and is lower than half the value of the Basic.

The Verdict

The Kinu M47 Basic is an costly however fantastically engineered espresso grinder. The sturdy construct high quality, precision machining, and revolutionary grind setting system mix to make it top-of-the-line guide burr grinders available on the market for espresso lovers. Whereas the associated fee could be exhausting to swallow, the lower-price Simplicity and Phoenix fashions make Kinu’s M47 grinders enticing to a broader viewers.
