Precision — Touchscreen Espresso Grinder

Precision GS4 — 64 mm Flat Burrs, Timed Dosing

The largest burr set in the home Precision range at 64 mm, driven through a touchscreen interface with a built-in shot timer. Set a timed dose or take over manually, and adjust the grind with the micrometric wheel on the front.

The GS4 sits above the GS7 in the range on burr size alone — 64 mm flat stainless steel burrs against the GS7's 60 mm. That extra diameter carries more cutting surface per rotation, which generally means a faster, cooler grind and finer control over particle consistency as you approach the fine end of the espresso range. It is the grinder to reach for if you have found the smaller burr sets in this range limiting.

Control runs through a touchscreen rather than a physical dial, with a shot timer built in and a choice of a timed dose or full manual operation. You start the grind by pushing the portafilter against the front button, which is a small detail that speeds up a busy morning — no separate switch to hunt for. The micrometric grinding wheel handles fine adjustment, and a dosing cup is included for measuring what comes out.

What sets the GS4 apart

64 mm flat burrs

The largest burr diameter in the home Precision range. More cutting surface per rotation typically means a faster grind with less heat transfer and finer control at the espresso end.

Shot timer built in

A timer on the touchscreen lets you track extraction time alongside grind and dose, which is genuinely useful for dialling in rather than guessing at three variables independently.

Push-to-start grinding

Push the portafilter against the front button and the grind begins. One less step than reaching for a separate switch, which matters when you are moving quickly in the morning.

Timed dose or manual

Set a dose time on the touchscreen for repeatable results, or switch to manual grind whenever you want direct control — useful when changing beans or dialling in from scratch.

Who it suits

  • Home baristas who want the largest burr set available in this range
  • Anyone who has found 60 mm burrs limiting and wants to step up
  • Buyers who prefer a touchscreen and shot timer over a purely manual grinder
  • Households where repeatable timed dosing matters day to day
  • Serious home setups pairing with a quality espresso machine

Getting the best out of it

Use the shot timer alongside a scale rather than instead of one. Time tells you how the shot is flowing; weight tells you what actually came out. Together they give you a much faster path to dialling in than either alone, particularly when you change beans or roast dates.

Clean the 64 mm burrs on a regular schedule — a larger burr set holds more retained coffee, so a build-up of oils takes slightly longer to show but affects a larger cutting surface once it does. Pair the GS4 with fresh coffee beans, and browse the wider Precision range for tampers and dosing tools. If you are still choosing a machine, see home coffee machines, or compare against the rest of the home grinder collection.

Frequently asked questions

How does the GS4 compare with the GS7?

The GS4 uses larger 64 mm flat burrs against the GS7's 60 mm, and adds a touchscreen with a built-in shot timer in place of the GS7's touchpad. Both offer timed dosing alongside a manual grind option.

What does the shot timer actually do?

It tracks extraction time on the touchscreen while you pull a shot, letting you monitor how long the espresso takes to run alongside your grind and dose settings. Used with a scale, it gives a fuller picture for dialling in than grind or dose alone.

Does pushing the portafilter against the button start the grind automatically?

Yes. The front button is designed to be triggered by pressing the portafilter against it, which starts the grind without needing to reach for a separate switch.

Can I still use it as a purely manual grinder?

Yes. The touchscreen lets you select a manual grind option in addition to the timed dose setting, so you retain full manual control whenever you want it.

How much bench space does it need?

The GS4 measures 130 mm wide, 210 mm deep and 465 mm high. Allow clearance above the 465 mm height so the hopper lid can be lifted and filled without moving the grinder.
