Espresso vs filter grinders — which Precision GS model is right for you?

Precision Coffee Tools — Grinder Buying Guide

Espresso grinders · Filter grinders · Single dose & on-demand · 60mm & 80mm burrs · Compared by use case

The difference between an espresso grinder and a filter grinder is grind fineness and consistency. Espresso grinders are built to grind fine and dose on demand for a pressurised shot, while filter grinders grind coarser for pour over, drip and other immersion methods. The Precision GS range includes models tuned for each — and a few that do both. This guide compares every Precision GS grinder by burr size, dose style and best use, so you can pick the right one in a couple of minutes.

What is the difference between an espresso grinder and a filter grinder?

An espresso grinder produces a fine, uniform grind and is usually dosed straight into a portafilter, because espresso relies on tightly packed coffee resisting nine bars of pump pressure. A filter grinder produces a coarser grind for brew methods like pour over, plunger and batch brew, where water passes through more slowly under gravity. The burrs, motor and grind-adjustment range are tuned differently for each job, which is why most baristas keep the two roles separate.

The Precision GS range compared

Every Precision GS grinder uses stepped or stepless micrometric adjustment and grinds directly into a portafilter or dosing cup. The main differences are burr size, hopper capacity, dosing style and whether the model is tuned for espresso or filter. The table below compares the range at a glance.

Specifications can change between production runs — always confirm the current spec on each product page before buying.

Which Precision grinder is best for home espresso?

For home espresso, the GS2 suits compact setups, while the GS7 steps up to a larger hopper and programmable single or double dosing for higher volume. If you change beans frequently and want almost no leftover grounds between shots, the GS0 V2 single-dose grinder is the standout, thanks to its zero-retention pump-action hopper. Choose by how often you brew and whether you value dose programming over a smaller footprint.

Which Precision grinder is best for filter coffee?

For filter coffee, the GS1 is a compact entry point, while the GS3 and GS5 use larger 80mm flat burrs for faster, cooler grinding suited to pour over, batch brew and plunger. The GS5 adds a touchscreen with timed dosing if you want repeatable filter doses without weighing each time. Pick the GS1 for a small kitchen, or the GS3 / GS5 if you brew filter daily or for more than one person.

Should you single dose or use a hopper?

Single-dose grinders like the GS0 V2 weigh in only the beans you need for one brew, which keeps coffee fresher and makes switching beans clean and waste-free. Hopper-fed grinders hold a larger volume for back-to-back grinding, which suits cafés and households brewing the same beans all day. If you rotate between several roasts, single dosing wins; if you grind the same coffee repeatedly at speed, a hopper is more convenient.

Frequently asked questions

Can one Precision grinder do both espresso and filter?

Yes. The GS0 V2 is designed for both espresso and filter thanks to its wide stepless adjustment range, making it the most flexible single grinder in the range. Dedicated models like the GS2 (espresso) or GS3 (filter) are tuned more specifically for one role.

What is the difference between the GS3 and GS5?

Both are filter grinders with 80mm flat burrs. The GS3 uses a manual push-to-grind operation, while the GS5 adds a touchscreen interface with a programmable timed dose and shot timer for more repeatable results.

Are flat or conical burrs better?

Neither is universally better. Flat burrs tend to produce a more uniform particle size favoured for clarity, while conical burrs (as in the GS0) are often praised for body and run cooler at lower power. The right choice depends on your taste and brew method.
