Option-O · Flat burrLagom P64
A 64mm single-dose flat burr grinder from Melbourne's Option-O, built around a CNC-machined unibody, swappable SSP/Mizen burr sets, and a variable-RPM motor. Long considered a benchmark for premium single-dosing, though we hear the price tag every time we recommend it.
The short version
This is a grinder for someone who already knows they want to fuss over burr choice and RPM dial-in, not someone looking for a plug-and-play upgrade from a Rocky.
Accept the price and the sporadic small-batch availability, or buy a DF64V and put the difference toward beans.
Why people buy it
- CNC-machined 6061-T6 aluminum body with tolerances to ±0.02mm, feels like it will outlast several coffee habits
- Genuine near-zero retention single-dose workflow with an integrated 58mm portafilter fork
Why they don’t
- Eye-watering price for a 64mm grinder when 84mm+ alternatives exist near the same money
The full tally
- CNC-machined 6061-T6 aluminum body with tolerances to ±0.02mm, feels like it will outlast several coffee habits
- Genuine near-zero retention single-dose workflow with an integrated 58mm portafilter fork
- Swappable 64mm burr sets (Mizen in-house or SSP) let one grinder cover espresso, filter, and everything between
- Variable RPM (200-1400) is a real tuning lever most grinders in this class don't offer
- Eye-watering price for a 64mm grinder when 84mm+ alternatives exist near the same money
- Small-batch production means frequent sell-outs and long waits between restocks
- RPM dial is numbered 1-9 with no actual RPM readout, so dialing in speed is trial-and-error
- Discontinued by the manufacturer and replaced with the Lagom P80, so stock is now limited to leftover retailer inventory and the secondhand market

Worth knowing before you buy — Most owners wish they had committed to the P64 sooner instead of chasing cheaper steppers—repeatability compounds value over time.
“The grinder feels extremely robust, and it's a pleasure to use.”
“But the P64 is definitely a superior grinder.”
“The unit is well made and very easy to use as well as being the most repeatable grinder I have ever used.”

Living with it
The part spec sheets skip: counter space, upkeep, and what owners learn later.
The honest note — Owners rarely upgrade off the P64 itself; the more common path is adding a second burr set (HU vs Unimodal) rather than a new grinder. With Option-O now pushing buyers to the newer Lagom P80, anyone shopping today should weigh the P80 or a DF64V/Niche Zero against hunting down remaining P64 stock.

Coffee scale with timer — Espresso is a ratio. A 0.1g scale with a built-in timer is the single biggest consistency upgrade for any manual machine.

- Dosing cup — Pairs with single-dose grinding — grind into the cup, swirl, and transfer to the portafilter cleanly.
- Grinder cleaning kit — Brushes and grinder tablets keep retention and stale grounds in check.
Feed it right
Week one is dial-in — and stale beans will lose it.
Coffee more than a few weeks past roast won’t extract predictably, and a new grinder gets blamed for it. These burrs lean bright — washed single-origins with real acidity are where they earn their price.

Common questions
Is the Option-O Lagom P64 still available new?
It has been discontinued by Option-O and replaced with the Lagom P80; remaining new stock is limited to leftover retailer inventory, with the secondhand market otherwise the main source.
Which burr set should I choose for the P64?
SSP High Uniformity or the Mizen 64ES suit traditional espresso with blends and medium/dark roasts, while SSP Unimodal or the Mizen 64OM favor light roasts, filter, and higher-ratio pours.
How much retention does the P64 have?
Option-O and retailers quote under 0.1g with RDT (Ross Droplet Technique) and under 0.2g without it, which is effectively zero for daily single-dosing.
