Quick Answer: The Mazzer Philos is a 64 mm flat-burr single-dose grinder that sells for $1,595 at every US dealer we checked on November 11, 2026, up from $995 in September 2024. Published tests support its low-retention claim: Wired measured about 0.1 g of retention on espresso and Tom’s Guide averaged 0.8% over three 20 g doses. Buy it if you mainly make espresso and will choose your burr set up front (I200D for lighter roasts, I189D for classic Italian espresso). Skip it if you mostly brew drip coffee, want adjustable motor speed, or would rather spend $689 on a Niche Zero.

The Philos was Mazzer’s first electric single-dose grinder. It was shown at HostMilano in October 2023, and Daily Coffee News reported that US sales were expected in early 2024. It takes the commercial-grinder maker’s burrs and motor and puts them into a home-sized body. This review is based on Mazzer’s Philos spec sheet and owner’s manual, the Mazzer US store and five other US dealers, and published reviews from Wired, Tom’s Guide and Kaffeemacher. We don’t test grinders ourselves, so every measured figure below names the publication that measured it.

What $1,595 buys, and what it used to cost

Every US dealer we checked lists the Philos at the same $1,595, and neither burr set nor color changes the price. That uniformity points to a minimum advertised price, so don’t expect a discount from shopping around. Clive Coffee was running a Black Friday gift-with-purchase promotion instead of a price cut.

The price has climbed four times since the US launch. Archived snapshots of Mazzer’s US store show this path:

February to March 2026$1,495+50%
October 2026 to today$1,595+60%

That history matters when you read reviews. Wired’s February 2026 review describes a suggested price that “crept up to around $1,500” after “a preorder offer closer to $1,000”, and Tom’s Guide reviewed it at $1,495 the same month. Clive Coffee’s own FAQ still says “At $1,495”. The value verdicts in older reviews were written when the Philos cost $100 to $600 less than it does now.

Mazzer’s US store also sells a growing list of add-ons, most of them added in April 2026: a Flanged Cup ($119), a cup lid ($49), a Burr Centering Jig made for the Philos ($89), a stainless hopper cover ($95), replacement wing screws ($49), a 53 mm canister ($35) and a spare Dose Finisher ($25). Replacement I200D or I189D burrs are $160 a set.

I200D or I189D: the choice you make at checkout

Mazzer offers the Philos with one of two 64 mm burr sets, and both versions cost $1,595. The spec sheet says both work from espresso to batch brew, but it describes them very differently.

I200DI189D
FittedAt the factory, by defaultAt the factory, on request
Mazzer's descriptionVery uniform particle size, low fines, flavor clarity, acidity and fruity notes"Evolution of the iconic Mazzer Mini burrs"; full body, velvety mouthfeel, medium-dark roasts, traditional Italian espresso
Kaffeemacher particle-size peak188 micrometers, narrower and higher206 micrometers, broader
Kaffeemacher's cup notesClearer, more complex cups, sometimes with less body; harder to balance with medium-dark roasts; its choice for filterDense, body-forward but balanced espresso with reduced acidity; lacked clarity with lighter roasts
Spare set$160$160

The practical rule: pick I200D if you buy light to medium roasts from specialty roasters, and I189D if your coffee is medium-dark and you want the thick, chocolatey espresso of an Italian bar. Wired found the Philos’s espresso with the I200D burrs “especially notable for lighter roasts”.

Choosing up front matters because swapping later is more work than the marketing suggests. Mazzer says you can open the grinding chamber “without tools”, but Wired notes you need a Phillips screwdriver to change the burrs. The manual lists burr replacement under jobs for “skilled technical personnel”, and Mazzer now sells an $89 centering jig for the Philos. A second burr set brings the total to $1,755.

Retention: what “zero” looks like in published tests

Mazzer markets the Philos as “zero retention”. There’s no bellows. Instead, Mazzer uses vertically mounted burrs, a short chute, a spring-loaded “duct knocker” you pull after grinding, and a magnetic Dose Finisher tool that clears the last grounds from the chute. Three publications measured how close it gets:

SourceWhat they measuredResult
Wired (Matthew Korfhage, Feb 11, 2026)Grounds left inside after brushing out the grinderUnder 0.1 g on filter grinds, without the Dose Finisher; about 0.1 g on espresso
Tom's Guide (Erin Bashford, Feb 15, 2026)Output from three 20 g doses19.6 g, 19.9 g, then 20.0 g with the Dose Finisher; 0.8% average
Kaffeemacher (Aug 26, 2025)Temporary and permanent retention over six months0.1 g temporary plus 0.5 g permanent; an 18 g dose sometimes came out as 18.5 g, then 17.5 g

For context, Tom’s Guide measured 1.6% for the Baratza Encore ESP, 2.1% for the Breville Dose Control Pro and 2.7% for the Comandante C40 MK4 using the same method, and called the Philos “the lowest-retention grinder I’ve ever tested”. Kaffeemacher’s finding is the caveat: retained coffee that occasionally lets go can swing a single dose by half a gram either way. Kaffeemacher’s advice is to weigh the output, not only the beans you put in, which is easy with an espresso scale you already use for the shot.

The RDT contradiction

RDT means spritzing beans with a drop of water to cut static. Mazzer’s own documents disagree on it. The Philos spec sheet says its stainless steel burrs resist oxidation and moisture damage “even when using RDT”. The owner’s manual says: before filling the hopper, do not wet the coffee beans with water, water spray or any other liquid.

Until Mazzer resolves that, follow the manual, because that’s the document a warranty claim gets judged against. The good news is that you may not need RDT. Wired credits a grounding plate and the short chute with keeping static down, Tom’s Guide reported “minimal static”, and Kaffeemacher found “only minimal static problems” in the grinder itself. Kaffeemacher did see grounds sticking in the corners of the dosing cup. If clumps are your problem, a WDT tool in the portafilter breaks them up without wetting the beans.

The dosing cup and the workflow

The Philos’s stainless dosing cup clicks into place on magnets and fits 58 mm portafilters, which most reviewers liked. Kaffeemacher had a specific problem with it: the cup sinks all the way into the portafilter instead of resting on the rim, which left craters in the coffee bed and led to “massive channeling” in its tests despite WDT. It stopped using the stock cup. Mazzer added a $119 Flanged Cup, which rests on a flange, to its US store in April 2026. Mazzer doesn’t say whether that responds to the complaint. A third-party espresso dosing cup with side wings is the cheaper fix.

The other workflow points from the published reviews:

Espresso first, drip second

Wired scored the Philos 9/10 and called its espresso “best-in-class”, but listed “better with espresso than drip coffee” as a con. At coarser drip and pour-over settings, Wired’s reviewer saw “a few (but not many) coarse boulders”. The 60 g hopper is also a limit for brewers: Wired wanted 10 g more to grind for an eight-cup carafe in one go. Tom’s Guide gave the Philos an Editor’s Choice award and called it “the last grinder you’ll ever buy”. Its main complaint was price.

Not every reviewer agrees on filter. Kaffeemacher, which always used the I200D burrs for filter, called the Philos “an excellent filter coffee grinder” and said some of its best filter coffees of the year came from it. If filter matters to you, that points to the I200D; Mazzer pitches the I189D at Italian-style espresso. If you split your time evenly between espresso and filter and don’t want to spend $1,595, an all-rounder may suit you better. Our Fellow Opus review covers a much cheaper grinder built for that.

Size, noise and the US warranty

The Philos is narrow at 6 inches, but it’s 14 inches deep, 14.25 inches tall and weighs 27.5 lb. That’s three times the 4.1 kg (9 lb) Niche lists for the Niche Zero. The manual asks for at least 15 cm (6 inches) of clearance from walls and other appliances, so measure the depth of your counter under the cabinets before you order.

On noise, Mazzer’s manual gives 74 dB(A) ±2.2, measured as EU workplace exposure for four hours of use in an eight-hour day. Kaffeemacher measured 78.1 dB while grinding and noted its unit was noticeably loud when running empty. Niche lists 72 dB for the Zero.

The US warranty is the weakest part of the package. Mazzer’s US store terms give 365 days from the date the grinder leaves the warehouse. F&O Imports troubleshoots by phone first and then issues a return authorization. Freight is not refundable, returns carry a 20% restocking fee, and you’re asked to keep the original box for the whole warranty period. Tom’s Guide contrasted that 12-month term with Comandante’s lifetime warranty on its hand-grinder burrs. The CPSC recall database lists no Mazzer recalls as of November 11, 2026.

Who should buy the Mazzer Philos

Buy it if espresso is at least most of what you make, you change beans or roasts often enough for low retention to matter, and you have 14 inches of counter depth plus clearance. Choose I200D for light and medium specialty roasts and I189D for medium-dark, Italian-style espresso.

Skip it if you brew drip or pour-over most days, want adjustable motor speed, need a warranty longer than a year, or are buying your first good grinder. A $399 DF64 Gen 2.7 or a $689 Niche Zero covers most of the single-dosing benefit. Our espresso grind size guide helps whichever grinder you choose.

The bottom line

The Mazzer Philos is a 64 mm flat-burr single-dose grinder with a commercial maker’s motor, burrs and metal build. Three publications measured retention from under 0.1 g to 0.6 g, low enough that Tom’s Guide called it the lowest-retention grinder it had tested. It’s also $1,595, 60% more than in 2024, with a one-year US warranty, fixed motor speed and a burr choice you should make at checkout. If that price is fine and espresso is your focus, the published evidence supports buying it. If not, a Niche Zero or DF64 Gen 2.7 gets you most of the way for a fraction of the money.
